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.
Keywords: Pulsatile flow, Oldroyd fluid, Hartmann number and heat transfer
