Abstract

FLow generated in the expansion tube was numerically simulated to evaluate the test flow conditions including the test flow period. For this purpose, the chemically equilibrium flow is assumed and the boundary layer effect is considered. To identify the start of the test flow period, the contact surface is intentionally detected. The boundary layer generated from the foot of the propagating shock wave was found to significantly modify the flow structure and thus the test flow conditions. The modification of the flow structure due to the tapered nozzle was clarified. Some of the numerical results are validated with the respective experimental measurement. In summary, the test flow conditions and the test flow period were estimated.
