| Abstract: | The paper describes the simulation of spray and combustion in cylinder for a HD diesel by using AVL FIRE software. The images of spray and combustion are captured based on the endoscope system. The quality analysis is compared between the CFD simulation and optical test result in injection,combustion flame and soot concentration distribution. The CFD simulation model of spray and combustion in cylinder is validated to accurate. |
