Rarefied Flow Simulations of Heat Transfer Across Evacuated Cryogenic Tank Insulation Structures

What is it about?

Cryogenic tanks containing cryogenic liquid propellants can be made of carbon fiber-reinforced polymers using a sandwhich structure between the environment and the inner lining of the tank. When this sandwich structure is evacuated the insulation of such a tank is improved. A rarefied gas remains and the heat transfer across this gas is simulated using a particle-based flow solver.
