Experimental investigation of the interaction between high-temperature flows and materials
Abstract
The work described was carried out as part of a unified program aimed at studying the influence of hypersonic flows on materials and blowing on heat transfer. The experiments were limited to two problem areas: investigation of heat transfer in ionized and dissociated gas under conditions of intense boundary-layer blowing, and investigation of the shape of bodies subjected to the flows as a function of the flow rate and temperature. Sequential photographs of the disintegration of a fiberglass textolite in supersonic flow at Reynolds numbers of 70,000 and 340,000 are presented, along with shadow photographs of a paraffin model disintegrating in a M = 5 air flow at Re = 6,000,000. It is found that after a certain initial period of time, the frontal shape of the test object remains stable and that it depends on the material and on the Mach and Reynolds numbers.
