Convective Heat Transfer on An Inlet Guide Vane

Abstract

The flow and temperature fields around an inlet guide vane are determined numerically by a CFD method. Outer surface temperatures, heat transfer coefficient distributions, and static pressure distributions are presented. Three different thermal boundary conditions on the vane are analysed. The computed results are compared with experimental data. The governing equations are solved by a finite‐volume method with the low Reynolds number version of the k‐ω turbulence model by Wilcox implemented. It is found that the calculated results agree best with measurements if a conjugate heat transfer approach is applied and thus this wall condition is recommended for future investigations of film cooling of guide vanes and turbine blades.

Conjugate heat transfer with Large Eddy Simulation for gas turbine components

“…This example is typical of one of the main problems encountered during the design of combustion chambers [2,21]: the hot flow leaving the combustor must not burn the turbine blades or the vanes of the high pressure stator. Predicting the vanes temperature field (which are cooled from the inside by cold air) is a major research area [22,23,4]. Here an experimental set-up (T120D blade) developed within the AITEB2 European project was used to evaluate the precision of the coupled simulations (Fig.…”
