Heat generation due to interference of hypersonic flow by a protuberance on the surface of a hypersonic craft is an important topic of study. Generally, designers try to keep the surface smooth, but protrusions with size of the order of the local boundary layer thickness have to be expected. They interfere with the flow and make it locally three-dimensional. Increased heat transfer rates will be felt on the protrusion as well as regions in the close vicinity. It is essential that these rates are properly quantified and documented since if design adjustments are not made to accommodate them, the performance of the aircraft might fall, the worst case holding disastrous results for the vehicle itself [1].
