Comparison between the performance characteristics of porous plane and parabolic sliders in the presence of transverse magnetic field lubricated with conducting lubricant additives

A comparative study on the performance characteristics of wide porous plane and parabolic slider is investigated in this paper. The modified Reynolds equation is derived subject to Darcy’s condition for porous media. The closed form expressions for pressure, load carrying capacity and frictional force, and coefficient of friction is obtained. It is found that the effect of MHD and lubricant additives in conducting fluid is to increases the load carrying capacity and frictional force in porous media for both the sliders. But as the value of porous parameter increases load carrying capacity and frictional force decreases and coefficient of friction increases. Also the effect of porosity is prominent for plane slider than in parabolic slider.
