摘要

Investigation of the study is carried to analyse the mixed convective stagnation point flow of Casson nanofluid over an inclined stretching sheet. In this paper, we develop the Bernoulli wavelet integration operational matrix method to understand the entropy generation effect on MHD boundary layer flow of Casson nanofluid over an inclined stretching sheet, including the effects of mixed convection, viscous dissipation, thermal radiation, chemical reaction, thermophoresis and Brownian motion. The modelled equations are governed by a set of partial differential equations. With proper similarity transformation boundary layer governing equations are transformed into nonlinear ordinary differential equations. To validate the proposed method, a nonlinear system of differential equations with an exact solution is solved and compared with the Runge–Kutta–Fehlberg fourth-fifth order method and the Haar wavelet method. Also, we provide a comparison table with existing results exhibiting the correctness of the numerical findings. Further, we discuss different parameters on velocity profile, temperature profile, concentration profile, skin friction, Nusselt number, Sherwood number, entropy generation and Bejan number. The present study explores the increase of entropy generation for rising values of Brinkmann number and mixed convection parameter and effect reverse for Bejan number. Furthermore, there is a noticeable increase in Bejan number and entropy generation with rising thermal radiation values.
