Abstract
This article deals with the peristaltic flow of biviscosity fluid in an endoscope. This study concentrates on the MHD characteristics and endoscope effects for peristaltic flow of a biviscosity fluid. Exact solutions are computed. The importance of pertinent flow parameters entering into the flow modeling is discussed. It is observed that increases in viscosity coefficient β, Hartmann number M and value of radius ratio ɛ cause increase in all the pumping regions.
