Fluid Structure Interaction

Fluid structure interaction is a class of simulations when fluid flow changes the shape or orientation of a body, which in turn changes the fluid flow. Vorticity has applied this type of simulation to a range of problems including modelling:

•       A microprobe hitting solid water ice at high velocity
•       An ejection seat emerging into high-speed flow
•       Airbag inflation
•       Aerodynamic stability of flexible structures
•       Water impact
•       Parachute dynamics and inflation in subsonic and supersonic flow
•       Entry probe dynamic stability
