• PERISTALTIC FUID FLOW THROUGH MAGNETIC FIELD AT LOW REYNOLDS NUMBER IN A FLEXIBLE CHANNEL UNDER AN OSCILATORY FLUX

S. Ravi Kumar*

Abstract


The present paper investigates the peristaltic fluid flow through magnetic field at low Reynolds number in a flexible channel under an oscilatory flux. A perturbation method of solution is obtained in terms of wall slope parameter and closed form of expressions has been derived for axial velocity and transverse velocity and also Shere stress. The effects of various physical parameters on axial velocity, transverse velocity, shere stress and fluid flux have been computed numerically. It is noted axial velocity increases with increase in Reynolds number ‘R’ and transverse velocity remains positive for all constrictions and increases towards the boundary with increase in Reynolds number ‘R’ and negative and towards axis at dilation.


Keywords


Peristaltic fluid flow, the time average flux, Reynolds number, Magnetic field.
