Quasilinearization numerical technique for dual slip MHD Newtonian fluid flow with entropy generation in thermally dissipating flow above a thin needle

In the present article, we investigate the dual slip effect namely the velocity slip and thermal slip conditions on MHD flow past a thin needle. The entropy generation for the incompressible fluids that's water and acetone that flowing above the thin needle is discussed. The energy dissipating term and the magnetic effect is included in the axial direction. The leading partial differential equations are transformed to ODE by an appropriate similarity transformation and solved using a numerical technique that is the Quasilinearization method. The terms for the rate of entropy generation, the Bejan number, and the irreversibility distribution ratio are discussed. Each dimensionless number is shown with velocity slip and also with the magnetic parameter is presented in graphical form. In the result, we conclude that the entropy generation rate is increasing with the increase in thermal slip parameter also some increasing effect is found as the size of the needle increases

Automated summary

This article investigates the dual slip effect in MHD flow past a thin needle, discussing the entropy generation in incompressible fluids like water and acetone. By transforming partial differential equations to ODE and using the Quasilinearization method, the study shows how velocity slip and magnetic parameter impact the rate of entropy generation. The results suggest that an increase in thermal slip parameter and needle size lead to an increase in entropy generation rate.
