Convective heat transfer in magnetized flow of nanofluids between two rotating parallel disks

Inspired by several implementations (metal mining, turbine disc, spinning disk, mechanical engineering and drawing of plastic film) of nanoliquid flow between rotating disks, we have reported a theoretical analysis on magnetohydrodynamic flow of kerosene base liquid containing three different nanoparticles namely manganese-zinc ferrite, cobalt ferrite and nickel-zinc ferrite between two parallel rotating-disks. Thermal radiation and convection thermal-conditions are considered. Furthermore, the significant properties of induced magnetic field are accounted to control the flow and thermal transport phenomenon. Furthermore, the temperature distribution is improved by employing Cattaneo-Christov heat flux. This communication is critical in the engineering sector due to different implementations including power technology, cooling reactors, fuel cells etc. The system of nonlinear higher order dimensionless equations is found by applying appropriate similarities-transformations. The exact solution of such strong nonlinear equations is not possible therefore we construct the numerical solution by employing bvp4c (shooting approach) in the MATLAB. Physical trends of velocities, pressure and thermal fields are discussed in detail. The outcomes indicate that stretching parameter of lower disk causes improvement in axial and radial fluid velocity. Fluid radial velocity near the lower disk is improved for growing Reynolds number. Moreover, the thermal field is enhanced for growing thermal Biot parameter at lower disk.

Automated summary

This study presents a theoretical analysis of magnetohydrodynamic flow of kerosene base liquid containing three different nanoparticles between two parallel rotating disks, considering thermal radiation and convection thermal-conditions. By controlling the induced magnetic field properties, the temperature distribution is improved using Cattaneo-Christov heat flux. Numerical solutions are constructed due to the nonlinear nature of the equations, showing that the lower disk stretching parameter improves fluid velocities and thermal fields.
