Three-dimensional mixed convection flow, heat and mass transfer of Eyring-powell fluid over a convectively heated stretched sheet is inspected in this paper. The encouragement of Brownian motion, Thermophoresis and thermal radiations are accounted. Appropriate transformations are used to reduce the principal PDE’s into set of coupled highly non-linear ODE’s which are then solved numerically using RKF fourth-fifth order method. The consequence of several parameters on flow, heat and mass transfer characteristics are deliberated with the help of graphs and tables. It is observed that, the temperature and concentration profiles diminish for higher values mixed convection parameter.

Horizontal Circular Cylinder

Convective heat transfer occurs when heat is transferred from one level to another upon  the motion of fluid.  Understanding on the characteristics of fluid flow is essential since it will produce the desired output of the product.  therefore, this paper examines the mixed convection flow at lower stagnation point of horizontal circular cylinder on Brinkman fluid saturated in porous region with convective boundary condition. The influence of Brinkman, mixed convection and conjugate parameter on the flow field are studied.  To reduce the complexity of the equations, a suitable similarity transformation is used. The numerical results of governing equations are obtained via bvp4c tools in Matlab. The effect of  mixed convection, Brinkman and conjugate parameter on the temperature and velocity profile, skin friction coefficient together with Nusselt number are analysed and portrayed in graph and table form.  The velocity profile increased with improving mixed convection and conjugate value, but decreased with increasing Brinkman factor.  It is also discovered that the temperature decrease when the mixed convection parameter increase.  This theoretical results will benefit the researchers, particularly in the manufacturing industry, in validating experimental study data.
