TRANSITION PREDICTION ON TURBINE BLADE PROFILE WITH INTERMITTENCY TRANSPORT EQUATION

摘要

The paper presents the results of tests and validations of γ-Re{sub}θ model proposed by Menter at al [10], which was extended by in-house correlations on onset location and transition length. The tests performed were based on experimental data on the flat plate Test Cases available at ERCOFTAC Data Base as well as on experimental data of turbine blade profile investigated at Czestochowa University of Technology. Further on, the model was applied for unsteady calculations of the blade profile test case, where chosen inlet conditions (turbulent intensity, wake parameters) were applied. For the selected case numerical results were compared not only with the experimental data, but also with the results obtained with other transition models.
