Adaptation of a Three-Dimensional Numerical Simulation to Represent Gas Turbine Engine Compression Systems
Abstract
A new three-dimensional compression system simulation was constructed by coupling the three-dimensional Navier Stokes flow solver, NPARC, with source terms that model the effects of turbomachinery components. A stage by stage characteristic technique adapted from the one-dimensional compressor code, DYNTECC, was used to calculate the turbomachinery source terms. This report discusses the development, adaptation, and implementation of the stage characteristic approach for calculating sources used in NPARC. The distribution of the source terms from the one-dimensional domain to the three-dimensional domain is presented, and an investigation of the radial distribution of the sources during pre-stall compressor performance was conducted. A simple compressor, consisting of a single transonic rotor, was modeled because experimental data were available for comparison.
