Summary on Grant Application Form |
The vertical landing phase of aircraft such as Harrier or F-35 Joint Strike Fighter is a highly unsteady, complex aerodynamic problem. In particular, when the aircraft is in ground effect, the hot impinging jet flows can result in hot gas entering the engine with a potential loss of the airframe. Previous work in this area has computed Reynolds Averaged solutions on complex geometries or LES on simplified flows. This project will compute a large eddy simulation of a realistic aircraft geometry whilst descending towards the ground.Cambridge University are developing a basic LES capabity in the Hydra unstructred CFD code. The project will use this a starting point and validate its capability for LES of impinging jet flows by comparing with existing structured code predictions. The fidelity of the simulation will be increased by improved flitering techniques and investigation of spatial discretization issues associated with high speed jets. Calculations will be carried out for Harrier type model in the experimental hot gas ingestion facilty.
