Abstract:
Natural gas based engines have significant contribution in different sectors and hence a very large no of studies have addressed this issue. In the current research we described the simulation process of non-premixed combustion
in a direct injection natural gas engine. Direct injection natural gas engines are used in many heavy duty vehicles. Similar
to diesel engines, high thermal efficiency and power density is maintained in such direct injection natural gas engines. Due
to the non-premixed nature of the combustion occurring in such engines, non-premixed combustion model of ANSYS FLUENT
13 can be used to simulate the combustion process. The CFD modeling of fuel injection and, combustion were performed to
simulate these phenomena and processes in a compressed natural gas direct injection engine. The details of the engine geometry chosen for the calculations were given along with and explanation for the modeling choice. The simulation we have
introduced has potential applications in the forth-coming studies as combustion chamber geometry, injection timing and
duration, compression ratios and piston geometry in order to increase the efficiency of the combustion process. We have described the work with good amount of experimental data.
