CFD Analysis of I.C. Engine Processes

<p><em>Modeling is a process of developing and using the appropriate combination of assumptions and equations that permit the critical features of the process to be analyzed. In case of spark ignition engine, fuel and oxidizer are mixed at the molecular level prior to ignition. Combustion occurs as a flame front; propagating into the unburnt reactants called as premixed combustion. Premixed combustion is usually occurs as a thin, propagating flame that is stretched and contorted by turbulence. The effect of turbulence is to wrinkle and stretch the propagating laminar flame sheet, increasing the sheet area and, in turn, the effective flame speed. The objective of project work is to do combustion modeling of single cylinder spark ignition engine of 124.7 cc ignitor bike by using computational fluid dynamics for predicting the turbulent flame speed at different equivalence ratio.</em></p&gt
