Dr Benjamin Goddard

Lecturer

My research combines mathematical modelling, numerics and rigorous analysis to tackle a range of interdisciplinary problems. These problems are generally complex (with phenomena that emerge from a collection of interacting objects) and multiscale (with important features at multiple scales, e.g. in time or space).

My current research focuses on three main areas:

  • Complex fluids and soft matter
  • Quantum molecular dynamics
  • Electronic structure theory

Prof Vasileios Koutsos

Professor

Research interests focus around Soft Nanostructures, Surfaces and Interfaces, and main research interests include the following themes: Self-assembly and self-organisation of polymers and nanoparticles on surfaces and interfaces, mechanics of materials with emphasis on nanostructures, adhesion, tribology and contact mechanics. Particular emphasis is laid on using the atomic force microscope (AFM) as an advanced multipurpose tool to probe not only the nanometer-scale morphology but also the nanomechanical, physicochemical, adhesive and frictional properties of surfaces, ultra-thin films, nanostructures and nanomaterials for both fundamental studies and applications (chemical industry, manufacturing, biotechnology & biomedicine, micro/nanoelectronics).

Professor Mark Linne

Chair in Combustion Engines

My research covers development of advanced laser diagnostics and their application to important flow fields, in order to develop better understanding and to support the development of predictive models. Recently I have focused mostly on fuel sprays and their “near field” dynamics (e.g. “spray formation”, also called “primary breakup” of the liquid jet). This research spans from very basic jets that intentionally isolate one breakup mechanism at a time (i.e. turbulence, shear, cavitation etc., to support the development of predictive models) to more applied jets (i.e. correlation of interior flows observed with optical tips with breakup). We sometimes study more realistic sprays in high pressure and temperature spray chambers and we include the effects of physical and chemical properties of fuels (i.e. alternative fuels). Our laser diagnostics work has recently focused on short-pulse (pico-and femto-second) lasers and the techniques we are working on include ballistic imaging, time gated optical sectioning, and most recently short pulse coherent anti-Stokes Raman spectroscopy (short pulse CARS).

Professor Davide Marenduzzo

Personal Chair in Computational Biophysics

Research interests centre on the areas of biological physics and soft condensed matter physics. In biological physics, I am interested in modelling DNA at several levels of complexity, either within bacteria or in eukaryotes, where it is associated with histones to form chromatin, and, at a larger scale, chromosomes. In soft matter, I am interested in liquid crystals and related materials, and the development of large scale simulation methods to study emulsions (droplets of water in liquid crystals, or of liquid crystals in water), as well as colloid-liquid crystal composites.  Projects of interest address the phase beheviour, hydrodynamics, rheology and electric-field switching of these liquid crystal based materials.

Dr Brian Peterson

Lecturer

My research is in laser and other optical based diagnostics to study the physics of reacting and non-reacting flows. The majority of my work is studying the turbulence transport, mixing, and combustion within internal combustion (IC) engines. The internal flow in engines are often amongst the most-complicated flows in technical applications today; they are non-stationary, yet periodic, turbulent flows that undergo rapid compression, expansion and gas exchange, which includes combustion and, in the case of direct-injection, two-phase flows with phase change. I am particular interested in advancing diagnostics that provide quantitative multi-parameter and multi-dimensional measurements to study the flow physics. I am an experimentalist, but enjoy working together with numerical partners to form strong teams that jointly address the challenges in turbulent flows and combustion science.

Professor Jason Reese

Regius Chair of Engineering

My research activities focus on multiscale fluids engineering systems: nano- and microfluidics, interfacial and other non-continuum flows, high-speed (rarefied) aerodynamics, and rapid granular/gas flows. Multiscale and multiphysics dynamics is characteristic of these areas of emerging technological importance, but affect the overall behaviour of the fluid flows in poorly-understood ways. This makes their simulation, design and control extremely difficult. The dynamics of the constituent fluid particles or molecules is key to understanding the overall flow behaviour. I am investigating new ways of modelling and simulating these flows from both molecular and hydrodynamic viewpoints. In particular, developing theoretical insight into the underlying non-continuum physics, and numerical simulation tools ranging from compressible fluid codes for extended hydrodynamic models through to highly-parallel molecular dynamics and DSMC codes. All of these numerical tools are released open-source in the OpenFOAM software.

Dr Dong-Hyuk Shin

Lecturer

My research interests lie in the high fidelity simulation of reacting flows and the development of combustion models.  More specifically, I am interested in developing robust, highly parallel CFD codes which can handle complex geometries with detailed chemical/fluid-dynamic processes.  These codes can be used to simulate combustion processes inside real engines such as gas turbines or internal combustion engines to help design  clean and efficient combustion systems.  In addition, I am also interested in developing models for various combustion processes such as combustion instability, turbulent flame speeds, mixing of fuel and oxidizer, droplet breakout.

Dr Jin Sun

Senior Lecturer

Research interests centre on granular materials and multiphase flow.

Our research focuses on mechanics and transport of granular materials and multiphase media. The main thrust is to understand the macroscopic behaviour of such materials from interactions at different spatial/temporal scales and to devise mathematical models for the rheology and dynamics. Multiscale modelling and computation is utilised as a paradigm, under which new methodology and tools are developed to solve the research problems.

  • DEM-CFD modelling of gas-solid flow dynamics in fluidised beds
  • Algorithms and computing code are being developed for a hybrid simulation approach coupling discrete element (DEM) and computation fluid dynamics (CFD).
  • Constitutive modelling of dense granular materials.
  • Constitutive models are being developed to link microstructure and particle properties to macroscopic behaviour of dense granular flow.
