The phenomenon of peristaltic transport has increased interest from researchers / investigators in several disciplines of engineering science. From a mechanical point of view peristalsis offers, constructing pumps in which the transported medium does not come in direct contact with any moving part (valves, rotors and plungers). This can be of great beneficial when medium is decomposable or highly abrasive under stress. Peristaltic flow problems are unsteady moving boundary value problems where the shape of the wave on flexible tube or channel is not known in priori and it deals with a...
