Three-dimensional numerical and asymptotic solutions for the peristaltic transport of a heat-conducting fluid (Q1341936)

Using Oberbeck-Boussinesq equations as a mathematical model, asymptotic solutions in closed form and numerical solutions are obtained for the peristaltic transport of a heat-conducting fluid in a three-dimensional flexible tube. The results show that the relation between mass flux and pressure drop remains almost linear and the efficiency of the transport depends mainly on the ratio of the wave amplitude to the average radius of the tube. However, the three-dimensional flow is much different from the two-dimensional flow.
