Abstract

The combined effect of surface roughness and magnetic field on the performance characteristic of the circular plates lubricated with conducting couplestress fluid (CCSF) has been studied. On the basis of the Christensen Stochastic model, the generalized stochastic Reynold’s equation is derived. Modified equations for the nondimensional pressure, load load-carrying capacity, and squeeze film time are derived. The results are presented both numerically and graphically and compared with conducting smooth surface case. It is observed that the surface roughness effects are more pronounced for couplestresses as compared to nonconducting Newtonian fluid (NCNF) in the presence of magnetic field.
导电耦合应力流体和横向磁场作用下,表面粗糙度对圆板挤压膜特性的影响
研究了表面粗糙度和磁场对导电耦合应力流体润滑圆板性能特性的综合影响。在克里斯滕森随机模型的基础上,导出了广义随机雷诺方程。导出了无因次压力、载荷承载能力和挤压膜时间的修正方程。给出了结果的数值和图形,并与导电光滑表面情况进行了比较。观察到,与非导电牛顿流体(NCNF)相比,在磁场存在下,耦合应力对表面粗糙度的影响更为明显。
