Abstract

This investigation focuses on flow and corresponding heat transfer behavior of viscoplastic Bingham- Papanastasiou fluid over a static radiated wedge. The modeled boundary layer flow governing equations are simplified by using similarity transformations. Numerical results are obtained for the economized equations by employing Runge-Kutta and Newton’s method. The impact of the associated parameters concerned with the fluid properties, friction factor and local Nusselt number are determined. It is found that the thermal radiation parameter improves the heat transfer rate. Bingham number boosts the friction at the wall and reduces the heat transfer rate. Improvement in Bingham number reduces the free surface movement and velocity of the fluid increases.
