Numerical study of heat and mass transfer analogy for a simulated turbine endwall

In the present work, numerical investigation of heat and mass transfer analogy on a simulated turbine blade endwall is conducted. For similar geometrical configurations, the experimental boundary conditions of heat and mass transfer are equivalent from the physical point of view, i.e. constant wall temperature in heat transfer and constant wall concentration in mass transfer, but they are numerically modeled in different ways in this study. The three-dimensional Reynolds averaged Navier-Stokes equations (RANS) are solved using a commercial CFD-tool within the blade passage in an attempt to predict the flow physics. The main purpose of this paper is the validation of heat and mass transfer numerical simulation with respect to experimental data and the analysis of the analogy factor between heat and mass transfer using only computed results.
