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
