| The problem of time-dependent enhanced heat transfer in an incompressible viscous laminar fluid subjected to sinusoidal oscillations in circular pipes which are connected to a hot reservoir at one end and a cold reservoir at the other end has been examined numerically in detail. Three models were designed for the investigation of such an enhanced thermal pumping process and a computer code (ETP) was developed to implement all the numerical calculations.;To increase the understanding of the mechanism of thermal pumping, the periodic velocity profiles and Lagrangian displacements as well as tidal displacements at various Wormersley numbers (from ;This study has shown that the enhanced thermal pump is indeed a very effective tool for those problems where large amounts of heat must be transported without an accompanying convective mass exchange. The investigation also indicates that turbulent flow in the reservoirs is preferable to laminar conditions and should receive more attention in future studies. |
