Abstract
ABSTRACT
This investigation is carried out to simulate the in-cylinder non-reacting flow of a two stroke spark ignition internal combustion engine (SIE) with gasoline direct injection (GDI). Computer Aided Design (CAD) model was built based on the LUPOE-2D two stroke SIE geometries that had been used in experimental previous work. The computational fluid dynamics (CFD) analysis technique is used to predict in-cylinder flow turbulence levels, including root-mean square (RMS) turbulent velocity. The three dimensional domain is created using FLUENT-ANSYS 14.0. The mathematical model is validated against previous experimental data. The intake manifold inclination angles of 0, 10, 20, 30 and 40o are investigated of double intake manifold at engine speed of 1500 rpm. The results indicate that the highest RMS turbulent velocities are achieved at 30o inclination angle of the inlet manifold at the crank angles of 24, 17, 10o before top dead center BTDC and 0o at top dead center TDC. Also, it is found that, the maximum RMSs occur at 0.18 of the radius of the cylinder at crank angle of 24o BTDC but at 0.25 of the radius at crank angles of 17, 10o BTDC and 0o at TDC.
