ABSTRACT

The evolution of the flow field inside a homogenous charge compression ignition (HCCI) diesel engine during the intake stroke is studied using a computational fluid dynamics (CFD) model. The conditions of air and fuel at different inlet pressures and temperatures are modified to study the suitability in an HCCI engine. These sets of conditions correspond to the simulation of turbocharging and preheating systems involved in the development of a homogeneously charged compression ignition engine. Two-phase flow is assumed between air and fuel. The fuel used here is diesel. The Reynolds stress model is used to close the Navier-Stokes equations due to turbulent flow field. The SIMPLE algorithm is used in the solution convergence in which the residuals of the governing equations are reduced with second-order convection schemes. Mesh scales are changed to arrive at grid-independent results of velocity in the intake stroke. Time steps are reduced to less than a degree of crank angle in obtaining a time-independent solution. The inlet pressure of air is varied from 0 to 1 bar (gauge) for modeling the turbocharging operation. Fuel injection at different flow rates is attempted to maintain the identical air-fuel ratio. Fuel at elevated temperatures (less than flash point) is employed for better mixing with air. The condition of preheated air with fuel at room temperature is also explored. The effect of air-fuel mixing due to different inlet pressures and temperatures is studied in this work.
