As a part of this research, a bluff-body type flame holder with fuel injection was tested at atmospheric conditions and prospective results were obtained for the engine. However, the capability of the experimental facility was limited, and it was difficult to investigate the engine performance over a wide operating range. So a two-dimensional CFD (Computational Fluid Dynamics) code was developed to simulate engine performance over a wide operating range. The code is based on the SIMPLER algorithm, and the power law scheme is used for the discretization of the governing equations. Turbulence is simulated by Myong-Kasagi's low Reynolds number type kappa-epsilon model. Magnussen's eddy dissipation concept is used to simulate the combustion. In this report, details of the CFD code and some typical results of the numerical simulation are described., 資料番号: AA0004246000, レポート番号: NAL TR-1233}, title = {燃料噴出型保炎器周りの流れに関する数値シミュレーションコードの開発}, year = {1994} }
