Abstract

FLUID MECHANICAL OR CFD SIMULATION IS PLAYING AN INCREASINGLY IMPORTANT ROLE IN THE SIMULATION OF ENGINE PROCESSES, AS IT MAKES POSSIBLE THE MOST DETAILED PHYSICAL DESCRIPTION OF THE RELEVANT PROCESSES. THE OBJECTIVE OF THIS WORK IS TO SIMULATE SPRAY FLOW WITH DIFFERENT BREAK-UP MODELS AND INVESTIGATE THE EFFECT OF THESE MODELS ON DI DIESEL ENGINE COMBUSTION AND PERFORMANCE. IN THIS SIMULATION, THE 3 -DIMENSIONAL NAIVER-STOKES EQUATION IS SOLVED WITH SIMPLEC ALGORITHM. AN EDDY BREAK-UP COMBUSTION MODEL AND A DIESEL AUTO-IGNITION MODEL WERE IMPLEMENTED TO SIMULATE THE IGNITION AND COMBUSTION PROCESS IN A DIESEL ENGINE. ALL THE SIMULATIONS WERE CARRIED OUT BY THE USE OF FIRE CFD TOOL. RESULTS WERE VALIDATED WITH AVAILABLE EXPERIMENTAL DATA FOR OM_355 DI DIESEL ENGINE FOR MEAN CYLINDER PRESSURE. THE RESULTS SHOW THAT THERE HAVE BEEN GOOD AGREEMENTS BETWEEN EXPERIMENTS AND THE CFD CALCULATIONS. THE RESEARCH DEMONSTRATED THAT MULTIDIMENSIONAL MODELING IS USEFUL FOR DIESEL ENGINE SPRAY MODELING AND OPTIMIZATION.
