Description
Summary:	This study deals with the mechanism of transfer of heat and mass in the magnetohydrodynamic flow of Casson nanofluid past an extended sheet and the examination of how the motion gets affected due to Joule heating and thermal radiation which is nonlinear, under the influence of entropy generation. The solution to the non-dimensional form of ODEs is achieved using the spectral quasi-linearization method (SQLM). The error analysis has been performed through which we show that the proposed method SQLM, proves to be quite a good fit to the considered mathematical model. The influence of various parameters on the velocity, temperature, and concentration profiles, the entropy generation, and the Bejan number will be presented with graphs and analysis performed. The entropy generation gets increased as the values of Reynolds number (Re), magnetic parameter (M), Brinkman number (Br) and dimensionless constant parameter are improved, whereas it gets decreased on the improvement of Casson parameter and temperature ratio parameter. The value Bejan number gets reduced on increasing the values of Brinkman number (Br), temperature ratio parameter ( ), and dimensionless constant parameter while gets increased on increasing the value of Casson parameter.
