DEVELOPING A COMPUTATIONAL MODEL OF AXIAL OIL FLOW FROM A POROUS ROUGH HOLE

This study aims to present a new computational model for assessing how surface longitudinal roughness affects axial flow emerging from a hole. Christensen and Tonder's stochastic averaging model have been employed to develop a mathematical calculation that captures the impact of roughness. A closed–form solution for axial flow, including different physical parameters has been obtained. Graphical and tabular diagrams suggest that the effect of longitudinal roughness on the performance is higher as compare to the transverse roughness pattern. Additionally, it is observed that the eccentricity ratio plays a crucial role in improving bearing system.
