摘要:
A computational fluid dynamics (CFD) based dimensional analysis of the flow in the base region of a planetary re-entry configuration is presented. Reynolds number and free stream Mach number are found to have the dominant influence on the Mach number of the trapped recirculating flow in the wake. Prandtl number is found have the strongest influence on the temperature of the wake recirculating flow. Two associated flow phenomena, wake reverse flow shock (WRFS) and wake flow thermal inversion (WFTI) are introduced. The governing role of the Prandtl number on the wake flow energy budget and thus the base region heating is discussed.
