Fluid Structure Interaction

Fluid structure interaction is a class of simulations when fluid flow changes the shape or orientation of 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;
  •       and entry probe dynamic stability.
