Analysis of Boundary Layer Flow Second-Grade Hybrid Nanofluid Subject to Lorentz Force

Abstract

The suspension of nanoparticles in a fluid has been a sure way of steadily improving fluid behaviour. A further improvement in the fluid behaviour is achieved by the suspension of two dissimilar nanoparticles in a base fluid. This study analyses the boundary layer flow of second-grade hybrid nanofluid subject to Lorentz force. By considering Titanium Oxide and Molybdenum disulfide nanoparticles, due to their great lubricating and efficient heat transfer properties, the governing non-linear equations are formulated and rendered dimensionless with the help of similarity variables. The resulting boundary condition equations are transformed to initial condition equations by use of shooting technique and numerically solved by 4th-order Runge Kutta method in MATLAB bvp4c. It is noted that the fluid’s velocity profile increases with the increase in volume fraction and fluctuates with increasing fluid parameters and magnetic strength. The temperature profile grows with the Prandtl number and magnetic field and decreases with the increase in volume fraction and the second-grade fluid parameter.
