Simulation for Gas-Membrane Interaction of Folded Membrane Tubes during Inflation

Abstract:

It is very important for gas-membrane interaction between compressible ideal gas and elastic membrane structure of space folded tubes during inflation deployment. This paper analyses gas flow field of the folded tube by the finite volume method, and simulates inflation process of the membrane tube with different height of the baffle. A finite volume model of gas flow field is established in the folded membrane tube, and variations of the pressure inside the membrane tube are obtained with height of the baffle and inlet flow rate. And then, the gas-membrane interaction is calculated by couple the CFD and CSD solver. The results show that the pressure on the membrane wall increases with the inflation velocity, and inlet velocity of inflation gives rise to the vibration of the membrane.
