Exact analytical solutions for the piston effect in supercritical fluids under post-acoustic approximation — Short-time asymptotics, thermal penetration depth and comparison with the Spacelab D-2 experiments

Near the liquid–vapor critical point, fluids become highly compressible, giving rise to a special, strongly coupled thermo-mechanical process: the piston effect. In this phenomenon, a thin thermal boundary layer develops near a heated wall; owing to strong thermal expansion, this...
