In the combustor and turbine of hot components of advanced high-performance gas turbine, there exists complex ilow and heat transfer phenomenon. As the turbine inlet temperature increases, components interaction directly affects the combustion chamber and blade temperature level. The combustor/turbine interactions research progress, especially typical theoretical and experimental research, numerical simulation results, is summarized. The interaction issue includes hot streak, turbulence, radiation, swirl and wake. The fundamental research has made much progress, however, the verification and application under realistic engine condition need more efforts. Experimental facility and computational capability are important to design the system construction.
