An overshoot phenomenon of bearing temperature in hydrodynamic journal bearings may be observed during a sudden start-up experiment. This implies that the maximum acceleration operation exceed predicted one which can accurately by applying state-of-the-art steady state thermohydrodynamic lubrication (THL) model. paper presents including using simplified THL model is newly proposed for transient...

Considering thermohydrodynamic instabilities in the design of cooling systems has become a trend, which led to evolution thermal management. However, such instabilities, cause flow perturbations, are difficult explain by using physical theories. The aim this study was use parameter-based modeling technique, namely response surface methodology (RSM), characterize dynamics multiloop heat pipes (M...

Couple stresses because of magnetic particles additives on the lubrication performance a journal bearing system was embraced and scrutinized in current examinations theoretically. The governing equations Reynolds (pressure field), energy (temperature heat conduction field through solids) are coupled solved instantaneously term temperature viscosity. After these set equation pressure is obtained...
