MHD Carreau hybrid nanoliquid flow over a stagnation region of poignant needle: An enhanced heat transmission model

Abstract

An unsteady 2D MHD enhanced Carreau hybrid nanoliquid over a stagnation region of poignant needle with chemical reaction is studied numerically. The governing PDEs are condensed into system of nonlinear ODEs and attained equations are tackled by using bvp5c MATLAB scheme. Moreover, the impacts of numerous physical factors over the flow fields are confer and expressed through plots. Numerical results of Nusselt and Sherwood number, wall friction are inspected and displayed thru tables. The main motive of this investigation is to examine the thermal and mass transmission mechanism of Carreau hybrid nanoliquid under the action of magnetic effect and in the absence of magnetic effect. Results obtained reveals thatthe needle thickness factor is capable of diminishing fluid flow, heat transfer and enriching concentration description. The Weissenberg number diminishes the rate of flow whereas the reverse trend isobserved for thermal distribution. Evidently, heat transport mechanism is highly influential in magnetic effects rather in the absence of magnetic effect.
