INVESTIGATION THE PERFORMANCE OF 0-D AND 3-D COMBUSTION SIMULATION SOFTWARES FOR MODELLING HCCI ENGINE WITH HIGH AIR EXCESS RATIOS

Investigation the performance of 0-D and 3-d combustion simulation softwares for modelling HCCI engine with high air excess ratios

In this study, performance of zero and three dimensional simulations codes Ball - Glove Baseball Fielding - Senior that used for simulate a homogenous charge compression ignition (HCCI) engine fueled with Primary Reference Fuel PRF (85% iso-octane and 15% n-heptane) were investigated.0-D code, called as SRM Suite (Stochastic Reactor Model) which ca

Sensitivity of Numerical Predictions to the Permeability Coefficient in Simulations of Melting and Solidification Using the Enthalpy-Porosity Method

The high degree of uncertainty and conflicting literature data on the value of the permeability coefficient (also known as the mushy zone constant), which aims to dampen fluid velocities in the mushy zone and suppress them in solid regions, is a critical drawback when using the fixed-grid enthalpy-porosity technique for modelling non-isothermal pha
