RISDamköhler Number Analysis on The Effect of Ozone on Autoignition and Flame Propagation in Internal Combustion Engines
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: Ozone-assisted combustion has shown promise in stabilizing combustion and extending operating range of internal combustion engines. However, it has been reported that sensitivity of ozone quantity on combustion varies ...
Effect of Valve Opening/Closing Setup on Computational Fluid Dynamics Prediction of Engine Flows
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In computational fluid dynamics (CFD) simulations of internal combustion engines, one of the critical modeling parameters is the valve setup. A standard workaround is to keep the valve opens at a certain clearance (minimum ...
Comparison of Near-Wall Flow and Heat Transfer of an Internal Combustion Engine Using Particle Image Velocimetry and Computational Fluid Dynamics
Publisher: American Society of Mechanical Engineers (ASME)
Abstract: In this study, computational fluid dynamics (CFD) modeling capability of near-wall flow and heat transfer was evaluated against experimental data. Industry-standard wall models for RANS and large-eddy simulation (LES) (law ...
