Abstract

Due to the complexity of the flow and the difficulty of measuring heat transfer directly in gas turbines or even in turbine cascade, heat transfer coefficients have been extracted from data obtained in mass transfer measurements using the heat/mass transfer analogy. The present paper shows the validity of the heat/mass transfer analogy from separate heat transfer and mass transfer measurements on simulated turbine blades with equivalent experimental and geometric conditions. The Nusselt numbers from heat transfer experiments employing a constant temperature boundary condition are compared to the Sherwood number from mass transfer experiments employing a constant concentration boundary condition.
