Abstract

Computational Fluid Dynamics (CFD) techniques were used to simulate one of the branches of fluid mechanics that uses numerical methods and algorithms to solve and analyze problems that involve fluid flows. This project is prepared to run CFD simulation using FLUENT 6.1.22 software on existing direct fuel injector using Compress Natural Gas (CNG) and the designed is based on 2D axisymmetric. The medium used during this simulation is considered as methane, CH4 since CNG consist more than 90% mol of the methane gas. The gas penetration result from simulation will be compared with the actual value of experiment. The results for early readings give the validation data but in the middle till final, there are not very accurate. This is due to the setting during simulation which can give some effect to the result obtained.
