This research article deals with numerical study of micropolar lubrication in constant flow valve compensated hole entry hybrid journal bearing by considering the thermal effects. The bearing performance characteristics are computed by the solution of modified Reynolds, three-dimensional energy, and three-dimensional conduction equations. The results obtained numerically indicate that bearing performance is significantly affected by increase in temperature. Hence it is imperative to consider the thermal effects for bearing operating with micropolar lubrication to generate realistic bearing characteristic data.
