Numerical simulation for Homann flow of a micropolar fluid on a spiraling disk

In this article the Hamann stagnation-point flow of a micropolar fluid over a spiraling disk is considered. A spiraling motion is produced due to uniform rotation and linear radial stretching of the disk. The coupled ordinary differential equations are obtained through the similarity reduction of the governing flow equations of micropolar fluid. A numerical technique known as the shooting method is implemented for obtaining the numerical results. Important features of the flow are investigated for various values of the spiral angle, spiraling parameter and material parameters. (C) 2018 Elsevier Masson SAS. All rights reserved.
