Dr Andrew Aspden

Lecturer in Thermofluid Dynamics


Andy joined Newcastle University in January 2017 as a Lecturer of Thermofluid Dynamics.  He obtained an MMath from the University of Oxford in 2002, followed by a PhD in Applied Mathematics from the University of Cambridge in 2006. He was awarded a Glenn T Seaborg Fellowship at the Lawrence Berkeley National Laboratory, where he was a member of the Center for Computational Sciences and Engineering for five years. Before joining Newcastle University, he was a Lecturer of Applied Mathematics at the University of Southampton, a Lecturer of Computational Fluid Dynamics at Cranfield University, and before that a Lecturer of Engineering Sciences at the University of Portsmouth.

Andy's research involves mathematical analysis and high-fidelity three-dimensional numerical simulation to study the fundamentals of turbulence and combustion to enable the development and validation of engineering models that can be used to design efficient low-emission combustor technology for transport and power generation.

Andy's research interests include analysis and simulation of fluid mechanics, turbulence, combustion, and type Ia supernovae.

Direct Numerical Simulation of Turbulent Combustion

Combustion research focusses on the use of Direct Numerical Simulation of turbulent combustion for development and validation of turbulent flame models.

Transition to the Distributed Burning Regime

When turbulent premixed flames are exposed to sufficiently high levels of turbulence, a transition to distributed burning can be observed. 

Implicit Large Eddy Simulation

Implicit Large Eddy Simulation (ILES) exploits properties of non-oscillatory finite-volume numerical schemes to simulate turbulent flows without explicitly modelling small-scale dissipation of kinetic energy.

Monotone Integrated Large Eddy Simulations of Buoyant Turbulent Jets with Off-Source Heating

Andy's PhD thesis considered a laboratory analogue of the modified entrainment behaviour observed in cumulus clouds.
