Abstract:

A study was made of the flow which results when an initially uniform gas expands into a vacuum through a complete one-dimensional rarefaction wave and then strikes a solid wall or similar opposite facing rarefaction. Calculation of the asymptotic temperature at the wall or line of symmetry involves a molecular analysis of the initial stages of reflection. A direct simulation Monte Carlo method was supported by continuum calculations and experiment. A combined numerical analytical and experimental study was also carried out for the thermal forces on very small particles suspended in the atmosphere. Modified author abstract
