Rotating machinery heat and mass transfer research in the People's Republic of China

A survey of research on rotating machinery heat and mass transfer in the People's Republic of China has been made. Since the later part of 1950's, considerable research and development work has been conducted in this field in China in order to improve the performance and prolong the life of rotating machinery. The emphasis of gas turbine heat transfer has been made in this survey. The water cooling of generator and the heat transfer of rotary piston engine are also included. Researches on the measuring technique of rotating machinery such as the temperature measurement, heat flux gauge, turbulence measurement, optical measurement and flow field visualization are discussed. The following topics of gas turbine heat and mass transfer are included: numerical analysis of air cooling of turbine blades, internal cooling passage heat transfer, impingment cooling, film cooling, transpiration cooling of turbine blades, cooling of blade root tenon, cooling of rotor disc, film cooling of flame tube and cooling of afterburner.
