## Peristaltic transport in a tapered tube.(English)Zbl 0840.76099

The peristaltic flow of spermatic fluid along the VAR deferents is modelled as the axisymmetric flow of a Newtonian viscous incompressible fluid along a tapered flexible tube. There is a small perturbation $$\varepsilon$$ to the tube radius which varies with time and distance along the tube. The basic differential equations are established, and an expansion is obtained in powers of $$\varepsilon$$. The two special cases of small Reynolds number and long waves are considered by making further expansions. Numerical results are presented in graphical forms. The flux-rate appears to vary linearly with the pressure rise but this is not discussed.
