On pulsatile hydromagnetic flow of an oldroyd fluid with heat transfer

Srinivas S., Malathy T., Sachdev P. L.

Engineering Transactions

2007

Vol. 55, iss. 1

79-94

The problem of heat transfer to pulsatile flow of hydromagnetic viscoelastic fluid has been studied. Expressions for the velocity, temperature distribution and mass flow rate are obtained. The rate of heat transfer at the plates has also been calculated. These expressions are evaluated numerically for various values of the parameters. The influence of pertinent parameters on temperature, heat transfer coefficient and mass flux has been studied and numerical results obtained are presented graphically.

On the viscoelastic core of a line vortex embedded in a stagnation point flow

Erdogan M. E.

International Journal of Applied Mechanics and Engineering

2003

Vol. 8, no 4

577-588

The viscoelastic core of a line vortex embedded in a radially inward axisymmetric stagnation point flow for a Maxwell fluid and an Oldroyd B fluid is considered. Velocity, vorticity and stress distributions are calculated and compared with those of the Newtonian fluid. It is found that there are pronounced effects of viscoelastic properties on these distributions with respect to those of the Newtonian fluid.
