| Abstract: | Comparison for the mathematical models of two external heat transfer (EHT) codes, STAN5 and S1ICH, was done. Both codes were employed to calculate the EHT coefficients (EHTC) of two turbine blades, calling Von Karman Institute(VKI) high-pressure turbine guide vane and blade, and the results were compared with experimental data, which shows that S1ICH has higher precision on capturing onset of transition, and higher precision on predicting EHTC of turbine blades than STAN5. S1ICH can meet the requirement of engineering applications, which has the character of extensive applicability, good convergence and simple input. |
