The School of Physical Sciences under the College of Agriculture and Natural Sciences (CANS) has held its third seminar for the semester. The third seminar, held at the Faculty of Arts Conference Room, was on the theme " Reiterated聽Homogenisation聽Applied in Hydrodynamic Lubrication." Speaking at the seminar, a lecturer at the Department of Mathematics, Prof. Emmanuel K.聽Essel, noted that聽Homogenisation聽is a branch within mathematics that involves the study of Partial Differential Equations (PDE's) with rapidly oscillating coefficients. He said the main purpose of聽Homogenisation聽is to Approximate聽PDE's聽that easily lend themselves to numerical treatment in a computer. Prof.聽Essel聽stressed that Reynolds type of equation were widely used in the field of聽Tribology. According to him,聽Tribology聽deals with lubrication, wear prevention and friction control in machines, adding that "聽Tribological聽studies enables lubrication engineers to minimize cost of moving parts thereby producing more efficient, more reliable and more effective machine." He explained that, in the field of Hydrodynamic lubrication, the flow of fluid through machine elements such as bearings, gear boxes and hydraulic systems may be governed by the Reynolds equation. The mathematics don pointed out that equations were often used in聽analysing聽the influence of texture and surface roughness on the Hydrodynamic performance of different machine elements when a lubricant was flowing through it.ag
