CFD Analysis ofPetrol Internal Combustion Engine

Abstract

Optimizing operation for internal combustion engines requires the application of advanced essential technique. Moreover,an experimentalinvestigation, numerical 3DCFD simulation, is needed in order to obtain and investigate avision into the complex phenomena’swithin cylinder. In this paper, fluid flow inside a single cylinder of spark ignition engine (SI)Hyundai type was modeled dependingon the numerical simulation using ANSYS V15.0/ICE CODE, with dynamic mesh technique to study and estimatethecharacteristics flow under normal operation of octane fuel with respect to crank angle at a constant r.p.m. The engine modelwas done by SolidWorks environment. This work focused on the simulation of the intake, compression, expansion and exhaust stroke, including cold and combustion simulation, solving the governing equations (continuity, Renolds Average Navier Stoke, and energy equation). The code was validated against published data for present case, and the comparison showeda close agreement between the results and the maximum discrepancy was 17 %.
