Heat flow coupling analysis of high pressure turbine blade based on FINE/Turbo

To verify the accuracy of solving flow heat coupling of high pressure turbine using FINE/Turbo software, Mark II gas turbine blade is taken as the analysis object, different turbulence models and transition models are selected to perform numerical simulation, and the blade surface pressure distribution, distribution of B2B surface pressure, temperature, Mach number and turbulence kinetic energy, temperature distribution inside blade, and blade surface heat transfer coefficient are obtained and compared with test data. The results indicate that accurate results of flow heat coupling can be obtained by FINE/Turbo software, transition has great effect on calculation precision of blade surface temperature and heat conductivity, and the selection of turbulence models has little effect on blade surface pressure, but has great effect on distribution of temperature and heat conductivity.
