Entropy production in the swirling flow of viscous nanofluid over a stretching cylinder embedded in a porous medium

This article's major goal is to examine the steady, incompressible flow of viscous nanofluid above a swirling, stretchy cylinder immersed in a porous media when there is a fixed temperature at the boundary, and a uniform magnetic field operating in the radial direction. The similarity transformations are used to produce the ordinary differential equations. The MATLAB's function bvp4c is used to solve the resulting equations. Expressions for the Bejan, Nusselt, Sherwood, and entropy generation numbers are obtained, and the results are reported together with graphs for a few physical parameters. It is discovered that as the magnetic and permeability parameters N and K increase the due to resistance velocity diminishes.
