Numerical and experimental investigationg of a turbine guide vane with conjugate heat transfer method

Abstract

Three-dimensional steady-state conjugate heat transfer numerical method was utilized to study the flow and heat transfer characteristics of a turbine guide vane. In experiment, a real-sized turbine vane model and corresponding test section were designed. We verified the simulation accuracy of different turbulence models, coupling with transition model and limiter factor in conjugate heat transfer method. Compared with the experimental results, the results indicated that the SST model shows better accuracy and economy than other models studied in this paper.
