Predictions of Transient Flame Lift off Length With Comparison to Single Cylinder Optical Engine Experiments
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A stateoftheart, gridconvergent simulation methodology was applied to threedimensional calculations of a singlecylinder optical engine. A mesh resolution study on a sectorbased version of the engine geometry further verified ...
Validation of a Three Dimensional Internal Nozzle Flow Model Including Automatic Mesh Generation and Cavitation Effects
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Fuel injectors often experience cavitation due to regions of extremely low pressure. In this work, a cavitation modeling method is implemented in the CONVERGE computational fluid dynamics (CFD) code in order to model the ...
A Computational Study of the Mixture Preparation in a Direct–Injection Hydrogen Engine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper reports the validation of a threedimensional numerical simulation of the mixture preparation in a directinjection (DI) hydrogenfueled engine. Computational results from the commercial code CONVERGE are compared ...
