METHODS FOR MEASURING LARGE HEAT FLUXES,
Abstract
A number of methods are used for measuring heat fluxes in high-temperature jets and shock tubes: the exponential, i.e., calorimetric method (according to the heat quantity stored in a sample); according to the surface temperature of a sample; the method of surface points (according to temperature change at the ends of a sample); according to the time interval before commencement of melting; the method of a cooled calorimeter (according to heating and consumption of cooled water). With the aid of the exponential method and a cooled calorimeter, distributions of heat fluxes in the cross-section of a high-temperature gas jet are measured. The results obtained by the two methods agree quite well. (Author)
