Abstract

This paper aims to analyze the behavior of the stagnation-point flow and heat transfer over a convective and permeable shrinking sheet. The governing partial differential equations are converted into ordinary differential equations by similarity transformations before being solved numerically using the bvp4c function built-in MATLAB software. Results found that dual solutions exist for the shrinking parameter. Effect of suction/injection parameter on the skin friction and heat transfer coefficients as well as the velocity and temperature profiles are presented in tables and graphs. The analysis indicates that the skin friction coefficient and the local Nusselt number as well as the velocity and temperature were influenced by suction/injection parameter.
