The purpose of this study is to examine the magneto-hydrodynamic (MHD) and slip velocity effect on secant curved annular circular plates lubricated with couple stress fluid and to derive the modified Reynolds’s equation for non-Newtonian fluid under various operating conditions to obtain the optimum bearing parameters. Based upon the MHD theory and Stokes theory for couple stress fluid, the governing equations relevant to the problem under consideration are derived. This paper analyses the effect of slip velocity on secant curved annular circular plates with an electrically conducting fluid in the presence of a transverse magnetic field. It is found that there is an increase in squeeze film pressure, load carrying capacity and squeeze film time in secant curved annular circular plates due to the presence of magnetic effects with couple stress fluid and slip velocity.

This research takes into consideration heat assimilation and heat generation, as well as the dissimilar characteristics of the two fluids, to analyze the convective flow of the fluids in a vertical channel. Magnetoconvection in a vertical container with two electrically conducting regions is analyzed using a two-zone model. Both fluids are assumed to retain their transport properties. The channel walls are maintained at differing temperatures. The resultant coupled non-linear equations for momentum and energy are solved analytically by using the standard perturbation technique. When B_r=P_r E_c (heat conduction from a wall) is small, this technique may be used. Various elements affecting the velocity field, temperature field, and concentration field in connection to heat assimilation and heat production are discussed, and their effects are graphically shown. The effects of magnetohydrodynamics (MHD) on the observed velocities, temperatures, and concentrations were shown.
