Abstract
The aim of this study is to investigate the influence of the change in the intake manifold geometry on the flow behavior and air-fuel mixing formation within a fuel injector port in a single-cylinder engine with a dual-fuel model engine. In an optimization study supported by the commercial computational code ANSYS-FLUENT, various injector angles and entry angles of an intake manifold are established to analyze their effects on the mixing behavior that causes mixture formation. The injector angles (α) are being changed from 20° to 30° to 40° for an intake manifold with entry angle (β) levels of 20°, 25°, 30°, 35°. The total pressure recovery, pressure loss, mean of velocity distribution, turbulent kinetic energy, helicity, and mass fraction of methane (CH4) are analyzed to evaluate the performance of flow behavior for mixing enhancement. Based on the validated results, the numerical results provide a highly accurate solution for geometry problems.
