摘要：

An induction electrohydrodynamic (EHD) pump in an axisymmetric configuration was designed and built to examine the heat transfer enhancement which accompanies fluid pumping under laminar flow conditions. The apparatus was operated at several tilt angles between 0 (horizontal) and 90-degrees while the augmentation of heat transfer was measured and compared to typical forced pumping and natural circulation. The increase in the overall conductance value for EHD pumping compared to typical forced pumping and natural circulation was as high as 105 and 122%, respectively. This corresponded to a much higher increase in the inside convection coefficient, which was the only resistance to heat transfer being affected by induction pumping. The operating frequency had an effect on the peak overall conductance value.
