At hypersonic speeds, the deceleration of the fluid by the viscous processes in a boundary layer generally produces very high temperatures. One result of these high temperatures is an increase in the thickness encountered at the same freestream Reynolds number at lower speeds. Viscous interaction is one of a number of important high speed phenomena that require proper evaluation prior to making any realistic aerodynamic performance estimate for a high speed vehicle. It is the purpose of the report to experimentally investigate several interaction theories.
