Theoretical Investigation over the Effects of EGR, Fuel Reforming and Compression Ratio on the HCCI Engine Operation Fuelled with Ethanol
Published In: GJRE Part: A: Mechanical & Mechanics Volume: 12 Issue: 2 HCCI engines have great potentials in high efficiency with ultra-low NO and particulates emissions and high flexibility in using various fuels. They operate on the basis of auto-ignition and therefore the fuel chemical kinetic is the main ignition controller. Thus initiation of combustion is a determining parameter in the prediction of combustion behavior. The main focus of the present s...

Two-phase Gas/Liquid-Solid Flow Modelling
Published In: GJRE Part: A: Mechanical & Mechanics Volume: 12 Issue: 1 Sand particles present in the fluid flows extracted from oil wells causes many problems for oil and gas production companies. Collision of sand particles to the wall of oil transfer pipes and process equipment reduces wall thickness which is considered as a cause of erosion. One of the consequences of this problem is frequent failures and loss of valuable production time. Bends installed...
