Abstract

In this article influence of velocity partial slip is addressed on transportation of silicon dioxide and silicon carbide suspended in engine oil base fluid in presence of a constant magnetic field. In this investigation to get better lubrication performance, we considering two different lubricants namely SiO2 andSiC in the flow of engine oil as base fluid. Nanofluidic transport is performed owing to the rotational motion of the disk. Additionally, mechanism of heat transfer is reported through temperature jump conditions. The mathematical formulation is performed in cylindrical coordinates and the governing set of equations is simplified by invoking similarity analysis. Precise similarity solutions are established for the full range of slip coefficients by means of shooting algorithm. Also, a collocation based MATLAB routine is used for findings the solutions for Velocity, pressure and temperature distributions Important physical quantities such as skin friction coefficient and Nusselt numbers are calculated and displayed through bar charts. One of the key findings includes that lubrication can be enhanced by using SiO2 and SiC in engine oil. Moreover, sphere-shaped silicon dioxide engine oil-based nanofluid attains minimum temperature whereas maximum is attained by lamina shaped silicon carbide nanoparticles.
