Exponential space-dependent heat generation impact on MHD convective flow of Casson fluid over a curved stretching sheet with chemical reaction

The present article focuses on the effect of exponential space-dependent heat source on magneto-hydrodynamic Casson fluid flow over a curved stretching sheet along with chemical reaction and convective heat and mass flux boundary conditions. The equations that govern the flow are reduced from system of partial differential equations to system of ordinary differential equations with the assistance of similarity transformations, and after that, they are solved using the numerical technique Runge-Kutta-Fehlberg fourth-fifth-order method. The obtained numerical values are plotted through graphs for velocity, temperature and concentration profiles with various parameters, and the variations based on these plots are discussed. Here, it is incurred that the velocity and concentration fields increase with increasing curvature parameter, whereas temperature profile shows inverse relation. Also, increment of Casson parameter shows the significant change in all flow profiles. Both thermal Biot number and concentration Biot number have increasing impact on temperature and concentration profiles, respectively.
