Influence of swirl and ingress on windage losses in a low-pressure turbine stator-well cavity (2023)
Journal Article

As part of the drive towards achieving net-zero flight by 2050, the development of ultra-high bypass ratio engines will place greater importance on the efficiency of the low-pressure turbine. Stator-well cavities can be a significant source of loss w... Read More about Influence of swirl and ingress on windage losses in a low-pressure turbine stator-well cavity.

High-fidelity CFD-trained machine learning to inform RANS-modelled interfacial turbulence (2023)
Journal Article

In aero-engine bearing chambers, two-phase shearing flows are difficult to predict as Computational Fluid Dynamics (CFD) RANS models tend to overestimate interfacial turbulence levels, leading to inaccuracies in the modelling of the flow. Turbulence... Read More about High-fidelity CFD-trained machine learning to inform RANS-modelled interfacial turbulence.

A New Thermal Elasto-Hydrodynamic Lubrication Solver Implementation in OpenFOAM (2023)
Journal Article

Designing effective thermal management systems within transmission systems requires simulations to consider the contributions from phenomena such as hydrodynamic lubrication regions. Computational fluid dynamics (CFD) remains computationally expensiv... Read More about A New Thermal Elasto-Hydrodynamic Lubrication Solver Implementation in OpenFOAM.
