Impact of Convective Condition on Marangoni Convection Flow and Heat Transfer in Casson Nanofluid with Uniform Heat Source Sink

The work deals with the Marangoni boundary layer flow in a Casson nanofluid. The present phenomenon also included the interaction of chemical reaction, uniform heat source/sink effect and convective condition. The governing equations reduced to a set of non-linear ordinary differential equations with the suitable similarity transformations. The obtained ordinary differential equations are solved numerically by Runge Kutta Fehlberg-45 order method. The effect of important parameters on velocity, temperature and concentration distributions are analyzed and discussed through graphs. Investigation reveals that, the Marangoni number plays a connecting role between the velocity and temperature gradients on the boundary surface. Further, the larger values of heat source parameter can adds more heat to the fluid, which increases its temperature.
