The demonstration of heat - transfer measuring techniques and prospect of infrared thermal mapping techniques , main parts and performance indexes of a infrared camera , functional blocks and implementation of infrared processing software , experimental facility and measuring system of the wind tunnel has been made . the model emittance was experimentally determined and the three methods correcting directional emittance were compared . those problems of the infinite - slab model thickness and constant wall heat rates hypothesis , the determination of adiabatic wall temperature were discussed in a 1 - d heat conduction analysis
