A Renewed Approach for Large Eddy Simulation of Complex Geometries, Phase II

Completed Technology Project

Project Introduction

A Renewed Approach for Large Eddy Simulation of Complex Geometries, Phase II
The potential benefits of Large Eddy Simulation (LES) for aerodynamics and combustion simulation hvae largely been missed, due to the complexity of generating grids for complex topologies, and the requirement for boundary fitted grids which reduce the accuracy of the method. The Phase 2 Program builds on the Cartesian grid LES flow solver developed under Phase 1, and includes new techologies such as immersed boundary conditions, multigrid code acceleration, compressibility, and advanced subgrid scale models for turbulence and combustion. Experimental validation cases using NASA-sponsored experiments, and using actual aeroengine combustor hardware will be performed, comparing the LES flow solver results with experimental combustor exit temperatures, and with other code predictions, providing a unique opportunity for validation of the flow solver.
