Project description
The declaration of a climate emergency has led to initiatives to achieve a net zero target. To contribute to this target, transport must move towards electrification. Hybrid engines need to become smaller and more efficient, with stricter control of exhaust composition. This poses significant challenges to existing numerical simulation codes. They are often inadequate for the design industry.
This project will improve and solve these issues. We are using Direct Numerical Simulation (DNS) for the high fidelity simulation of turbulent combustion. This will improve fundamental understanding of the behaviour of turbulent combustion.
We will improve the simulation accuracy of low cost Reynolds-averaged Navier-Stokes (RANS) simulations.
This research will allow designers to improve efficiency and reduce emissions of spark ignition internal combustion engines. It offers the opportunity to do this at lower computational costs. At the same time, it maintains accuracy of predictions.
ESPRC (Engineering and Physical Sciences Research Council) and Ricardo UK are funding the research.
