Dimitris Drikakis, PhD, FRAeS, CEng, is a Greek-British applied scientist, engineer and university professor. His research is multidisciplinary. It covers fluid dynamics, computational fluid dynamics, acoustics, heat transfer, computational science from molecular to macro scale, materials, machine learning, and emerging technologies. He has applied his research to diverse fields such as Aerospace & Defence, Biomedical, and Energy and Environment Sectors. He received The William Penney Fellowship Award by the Atomic Weapons Establishment (AWE Plc) to recognise his contributions to compressible fluid dynamics. He was also the winner of NEF's Innovator of the Year Award [1] by the UK's Institute of Innovation and Knowledge Exchange for a new generation carbon capture nanotechnology that uses carbon nanotubes for filtering out carbon dioxide and other gases.
Drikakis obtained his mechanical engineering degree (1982–1987) from the National Technical University of Athens in Greece. His diploma dissertation was in biofluid mechanics and concerned pulsating blood flow in an anisotropic elastic tube.
He carried out his PhD (1988–1991) at the National Technical University of Athens (NTUA) in the Laboratory of Aerodynamics, Fluids Section. His PhD concerned the development of computational fluid dynamics methods for high-speed compressible flows and co-supervised by the Flight Physics Division of Messerschmitt-Bölkow-Blohm (MBB), a German aerospace manufacturer formed later on the Airbus Group.
In 1992, Drikakis joined as research scientist and later on as a team leader at the Institute of Fluid Mechanics (Lehrstuhl für Strömungsmechanik – LSTM) of the University of Erlangen–Nuremberg (Friedrich-Alexander-Universität Erlangen-Nürnberg) under the direction of Professor Franz Durst. He researched in fluid dynamics and high-performance parallel computing at the early stages of developing parallel computers during that period.
In 1995, he joined as a lecturer the University of Manchester Institute of Science and Technology (UMIST), merged later with the University of Manchester. He worked in the Fluid Mechanics Division under Professor Brian Launder and Professor Michael Leschziner. [2]
In 1999, he was offered a readership (associate professor position) at Queen Mary, University of London and became a full professor (professor of fluid dynamics) at the same university in 2001. He was 36 years of age.
In 2003 he joined Cranfield University as a professor and head of the Fluid Mechanics and Computational Science Centre. He was appointed head of the Aerospace Science Departments (2005–2010). In 2012, he established the department of engineering physics in the same university, which later evolved to the Institute of Aerospace Sciences. He left Cranfield in 2015. During his tenure at Cranfield University, he held various management and leadership posts, including the director of research in the School of Aerospace, Transport & Manufacturing.
In 2011, he was the founding director of the regional high-performance scientific computing centre at The Cyprus Institute in close partnership with the University of Illinois at Urbana-Champaign, US.
In July 2015, he was appointed as the executive dean of the Faculty of Engineering and professor of sngineering science at the University of Strathclyde, Glasgow, one of the UK's largest engineering schools. He worked with principal and vice-chancellor, Professor Sir Jim McDonald (electrical engineer). From 2015 to 2018, he held various executive posts as associate principal and executive director of Global Partnerships.
He left the University of Strathclyde in October 2018 to join the University of Nicosia in Cyprus as the vice president of global partnerships, [3] executive director of research and innovation, with a full professor (cross-appointment) in the medical school [4] and the School of Sciences and Engineering. [5] The University of Nicosia is a private, English-speaking university, the largest in Cyprus.

A discrete element method (DEM), also called a distinct element method, is any of a family of numerical methods for computing the motion and effect of a large number of small particles. Though DEM is very closely related to molecular dynamics, the method is generally distinguished by its inclusion of rotational degrees-of-freedom as well as stateful contact, particle deformation and often complicated geometries. With advances in computing power and numerical algorithms for nearest neighbor sorting, it has become possible to numerically simulate millions of particles on a single processor. Today DEM is becoming widely accepted as an effective method of addressing engineering problems in granular and discontinuous materials, especially in granular flows, powder mechanics, ice and rock mechanics. DEM has been extended into the Extended Discrete Element Method taking heat transfer, chemical reaction and coupling to CFD and FEM into account.
In computational chemistry, molecular physics, and physical chemistry, the Lennard-Jones potential is an intermolecular pair potential. Out of all the intermolecular potentials, the Lennard-Jones potential is probably the one that has been the most extensively studied. It is considered an archetype model for simple yet realistic intermolecular interactions. The Lennard-Jones potential is often used as a building block in molecular models for more complex substances. Many studies of the idealized "Lennard-Jones substance" use the potential to understand the physical nature of matter.
Computational fluid dynamics (CFD) is a branch of fluid mechanics that uses numerical analysis and data structures to analyze and solve problems that involve fluid flows. Computers are used to perform the calculations required to simulate the free-stream flow of the fluid, and the interaction of the fluid with surfaces defined by boundary conditions. With high-speed supercomputers, better solutions can be achieved, and are often required to solve the largest and most complex problems. Ongoing research yields software that improves the accuracy and speed of complex simulation scenarios such as transonic or turbulent flows. Initial validation of such software is typically performed using experimental apparatus such as wind tunnels. In addition, previously performed analytical or empirical analysis of a particular problem can be used for comparison. A final validation is often performed using full-scale testing, such as flight tests.
Smoothed-particle hydrodynamics (SPH) is a computational method used for simulating the mechanics of continuum media, such as solid mechanics and fluid flows. It was developed by Gingold and Monaghan and Lucy in 1977, initially for astrophysical problems. It has been used in many fields of research, including astrophysics, ballistics, volcanology, and oceanography. It is a meshfree Lagrangian method, and the resolution of the method can easily be adjusted with respect to variables such as density.
Fluid–structure interaction (FSI) is the interaction of some movable or deformable structure with an internal or surrounding fluid flow. Fluid–structure interactions can be stable or oscillatory. In oscillatory interactions, the strain induced in the solid structure causes it to move such that the source of strain is reduced, and the structure returns to its former state only for the process to repeat.

Physics of Fluids is a monthly peer-reviewed scientific journal covering fluid dynamics, established by the American Institute of Physics in 1958, and is published by AIP Publishing. The journal focus is the dynamics of gases, liquids, and complex or multiphase fluids—and the journal contains original research resulting from theoretical, computational, and experimental studies.
The material point method (MPM) is a numerical technique used to simulate the behavior of solids, liquids, gases, and any other continuum material. Especially, it is a robust spatial discretization method for simulating multi-phase (solid-fluid-gas) interactions. In the MPM, a continuum body is described by a number of small Lagrangian elements referred to as 'material points'. These material points are surrounded by a background mesh/grid that is used to calculate terms such as the deformation gradient. Unlike other mesh-based methods like the finite element method, finite volume method or finite difference method, the MPM is not a mesh based method and is instead categorized as a meshless/meshfree or continuum-based particle method, examples of which are smoothed particle hydrodynamics and peridynamics. Despite the presence of a background mesh, the MPM does not encounter the drawbacks of mesh-based methods which makes it a promising and powerful tool in computational mechanics.
In computational fluid dynamics, the immersed boundary method originally referred to an approach developed by Charles Peskin in 1972 to simulate fluid-structure (fiber) interactions. Treating the coupling of the structure deformations and the fluid flow poses a number of challenging problems for numerical simulations. In the immersed boundary method the fluid is represented in an Eulerian coordinate system and the structure is represented in Lagrangian coordinates. For Newtonian fluids governed by the Navier–Stokes equations, the fluid equations are
Joel Henry Ferziger was a Professor Emeritus of mechanical engineering at the Stanford University, Palo Alto, California, United States. Ferziger was an internationally recognized authority in fluid mechanics. His main area of research was computational fluid dynamics. He was known for developing computer simulations to model complex turbulent flows.
In applied mathematics, the finite pointset method (FPM) is a general approach for the numerical solution of problems in continuum mechanics, such as the simulation of fluid flows. In this approach the medium is represented by a finite set of points, each endowed with the relevant local properties of the medium such as density, velocity, pressure, and temperature.

Non ideal compressible fluid dynamics (NICFD), or non ideal gas dynamics, is a branch of fluid mechanics studying the dynamic behavior of fluids not obeying ideal-gas thermodynamics. It is for example the case of dense vapors, supercritical flows and compressible two-phase flows. With the term dense vapors, we indicate all fluids in the gaseous state characterized by thermodynamic conditions close to saturation and the critical point. Supercritical fluids feature instead values of pressure and temperature larger than their critical values, whereas two-phase flows are characterized by the simultaneous presence of both liquid and gas phases.
