Boundary layer flow and heat transfer over a permeable shrinking cylinder with surface mass transfer

Bhattacharyya K., Gorla R. S. R.

International Journal of Applied Mechanics and Engineering

2013

Vol. 18, no. 4

1003--1012

In the present paper, the axisymmetric boundary layer flow and heat transfer past a permeable shrinking cylinder subject to surface mass transfer is studied. The similarity transformations are adopted to convert the governing partial differential equations for the flow and heat transfer into the nonlinear self-similar ordinary differential equations and then solved by a finite difference method using the quasilinearization technique. From the current investigation, it is found that the velocity in the boundary layer region decreases with the curvature parameter and increases with suction mass transfer. Moreover, with the increase of the curvature parameter, the suction parameter and Prandtl number, the heat transfer is enhanced.

Flow analysis of viscoelastic fluid due to a shrinking sheet

Nandeppanavar M. M., Siddalingappa M. N., Kemparaju M. C.

International Journal of Applied Mechanics and Engineering

2012

Vol. 17, no. 1

249-257

This work is concerned with the analysis of a two dimensional flow of a viscoelastic fluid (Walters' liquid B) induced by a shrinking sheet. The governing partial differential equations are first reduced to ordinary nonlinear differential equations by using the appropriate similarity transformation. An exponential solution is assumed to solve the considered boundary value problem. The effects of governing pertinent physical parameters on the flow characteristics are presented graphically and discussed.
