Abstract
This study has been conducted to utilize the open source code in analyzing the performance of a gas turbine engine. The turbine nozzle vanes, which are relatively simple to analyze among the gas turbine engine components, were selected for analysis, and the analysis was carried out by OpenFOAM which is the most well-known tool as an open source CFD code. Among the solvers provided by OpenFOAM, rhoSimpleFoam and rhoPimpleFoam were used to analyze the compressible flow, and the JANAF option enabled to apply the function of temperature to the thermal properties. rhoSimpleFoam was able to calculate quickly and correctly in the region below the Ma = 1, but not affordable for the transonic region with shock wave, which was compensated with rhoPimpleFoam with the transonic option resulting in converged solution. The calculated results by OpenFOAM were compared to those by ANSYS – CFX and showed good agreement.
