Thermal-EHL tribodynamic analysis of a spur-gear pair, using correction factors

A thermal-tribodynamic model was developed to study the produced vibrations in a pair of spur gears, considering rough anisotropic tooth surfaces, the use of Newtonian and non-Newtonian lubricants, and friction induced temperature effects. It consists of two sub-models, the contact model and the dynamic model. Outputs...

Modeling of air-fuel mixture flow in a marine four-stroke diesel engine to optimize performance and minimize pollutant emissions

This study proposes a computational framework that utilizes advanced Computational Fluid Dynamics (CFD)-based modeling and diesel-cycle analysis to analyze the emissions and performance of a high-speed marine four-stroke diesel engine. A three-dimensional sector model is created with an emphasis on a Perkins 404D-22 en...
