Abstract

Abstract

The peristaltic flow of Jeffrey fluid through a tube of finite length was studied.The fluid was electrically conducting in the presence of an applied magnetic field.Analysis was carried out under the assumption of long wavelength and low Reynolds number approximations.Expressions of pressure gradient,volume flow rate,average volume flow rate and local wall shear stress were obtained.The effects of relaxation time,retardation time and Hartman number on pressure,local wall shear stress and mechanical efficiency of peristaltic pump were studied.Reflux phenomenon was also investigated.Here the case of propagation of a non-integral number of waves along the tube walls was also examined,which were inherent characteristics of finite length vessels.
