Application Of Computational Fluid Dynamics Code On Flow Process Through Inlet Port Of Internal Combustion Engines
This paper aims at emerging steps to design more efficient Internal Combustion Engine (ICE) compared with what exists presently. To accomplish this aims, simulation with Computational Fluid Dynamics (CFD) code integrated with ANSYS to obtain very useful results using a modelled engine. The effectiveness of the tools cannot be over emphasized because they understood the fluid dynamics of most engines and is capable of evaluating the engine geometry and its mechanism both graphically and numerically. Also, the simulated results for the model under study was examine with comparative analytical test showing graphically display of swirl ratio and flow coefficient against lift values. Dynamic pressure difference of 0.031783Pa across the model after 63 iterations was evaluated. This attests fluid flow from one region of the inlet port to another. Also vector plot of velocity for high lift was simulated and results confirms the reliability of the tools because the CFD calculations verifies that swirl ratio and flow coefficient are good enough for the testing of fluid dynamics fundamental equations. Also results attests that the used application is capable to identify the region of the IC engine port with more flow. Therefore, test conducted with the codes were visible and reliable hence study was realistic.
