Correlation of Laminar and Transitional Heat Transfer Rates Measured in Base Type Separated Flows in a Shock Tube

摘要

Laminar heat transfer rate distributions were measured in the separated regions of a two-dimensional backward facing step, an axially symmetric backward facing step, a blunt two-dimensional base, a sharp protruding two-dimensional leading edge and in the leading edge bubble over the surface of a flat nosed two-dimensional model. The first three configurations had an initial boundary layer ahead of separation, while in the last two configurations separation occurred at the leading edge with approximately zero boundary layer thickness. All measurements were performed in the straight section of a shock tube. Maximum and average heat transfer rates were measured in the reattachment zone and over the separated region. (Author)
