概要

論文の詳細を見る
Conjugate heat transfer simulation method was implemented in the unstructured-mesh CFD solver to predict the thermal loads of cooled turbine vanes, Mark II and C3X. In this simulation, the fluid domain and solid domain are solved simultaneously satisfying the continuity of the heat flux and temperature on the boundary of the fluid and solid. In addition, γ-Re_θ transition model is applied to predict the boundary layer transition which often occurs in the flow around turbine blades and affects the material thermal load seriously. The predicted thermal load results from the two-dimensional computations are in close agreement with the measurement data capturing the transition on the suction side of the vanes.
