Abstract

The development of a new generation of high performance gas turbine engines requires gas turbines to be operated at very high inlet temperatures, which are much higher than the allowable metal temperatures. Consequently, this necessitates the need for advanced cooling techniques. Among the numerous cooling technologies, the inward flow cooling technology has superior advantages and relatively favorable application prospect. The recent research progress of the inward flow cooling of turbine blade in rotating is reviewed. Influence of passage section on heat transfer in rotating and the effect of rotating smooth passage on turbulent flow and heat transfer are discussed. The influence of rotating on impinging cooling and heat transfer of rotating cooling duct with staggered pin fins is also generalized. In the last, it is noted that major problems due for further research include: optimizing of inward passage configuration and synthesis study of rotation effect on flow and heat transfer in pin-fins duct. In addition, the interactional mechanism of inward flow and film cooling will be also investigated thorough.
