中文摘要	Aimed at the problem of isolator being seriously heated by aeroheating at a long time fly, effects of wall temperature on flow characteristics and performance of isolator are experimentally and numerically investigated in detail under the different entrance conditions including total temperature and total pressure. The results show that shock train is affected by the dual mechanism of isolator wall temperature and airflow total temperature. With an increase of wall temperature and a reduction of total temperature, the length of shock train increases. This tendency can be characterized by the variation of shock train length with ratio of wall temperature to total temperature, viz., shock train length increases with ratio of wall temperature to total temperature. Based on the present data, both the ratio of wall temperature to total temperature and specific heat ratio are introduced to modify the correlation of Waltrup and Billig [5] for predicting shock train length of practical design with the coverage of more physical influencing factors. © 2016, American Institute of Aeronautics and Astronautics Inc, AIAA.
