SUMMARY:Computational fluid-membrane interaction with application to super
 sonic decelerators - Dr Fehmi Cirak\, CUED

DESCRIPTION:Supersonic membrane decelerators\, like parachutes or inflatab
 le aero-shells\, are presently used for planetary re-entry in robotic miss
 ions. It is known from flight tests and experiments that such membrane dec
 elerators are susceptible to aeroelastic instabilities in certain flight r
 egimes. To study this\, we developed a numerical solution strategy by comb
 ining several novel developments in membranes\, fluid-membrane interaction
 \, fluid dynamics and block-structured adaptive mesh refinement. In this p
 resentation\, I will introduce the developed overall computational framewo
 rk and discuss\, in particular\, the challenges in modelling the structura
 l components of the membrane decelerators.
