Selecting the appropriate piston rod bearing is crucial for ensuring reliable engine operation. These bearings transmit the pressures between the piston and the cylinder wall, reducing friction and wear. Factors to consider when selecting a bearing encompass engine dimensions, operating conditions, load requirements, and lubrication system. Differe

Extruded finned tubes play a vital role in heat exchanger designs due to their high surface area to volume ratio. Recent research have focused on improving the efficiency of these tubes through various methods such as fin geometry optimization, material selection and flow regime manipulation. This article provides a comprehensive analysis of the op
