Numerical Investigation of Bumps and Oscillation in the Cylindrical Membrane Inflation

Abstract:

Numerical investigation on the fluid structure interaction in the cylindrical membrane inflation is performed by the Euler-Largrangian method. In membrane inflation, the vortex flow and wave system induced by the interaction between compressible jet flow and membrane appeared inside membrane. This phenomenon concentrates the stresses and generates a pair of bumps. The influences of oscillation and bumps on membrane working performance and safety are also investigated.
