|Mitigating the effects of under-vehicle airflow|
|Supervisor: Dr Adam Beagles|
|A major source of damage to rail vehicles is impacts from pieces of ballast and similar material. Rapid airflow associated with train movement is responsible for lifting the material from the track: the material then strikes the underside of the train, damaging equipment, and maybe leading to axle-failure and derailment.
This project will develop computational fluid dynamics models of flow between a rail vehicle and track and use these to determine trajectories of material experiencing these flows. It will then consider design changes to the underside of train carriages (e.g. placing baffles or filters) to reduce the severity and incidence of damage. It is expected that the simulation work will be supported by testing: using a wind tunnel, or another test rig developed by the student.
