Numerical simulational study on convective heat transfer process in tube-Side of Water Jacket-tube enhanced by Electrohydrodynamics

摘要: Aiming at the characteristics of Electrohydrodynamics(EHD)enhancement boiling heat transfer, based on fluid mechanics theory and mass transfer theory, electromagnetism, heat-mass electromagnetic, model tube-Side Water Jacket-tube was established with water as working fluid, numerical method employed to simulate EHD-enhanced coefficient in different DC high voltage under same conditions, then results compared experiment. The result shows that convective can be enhanced by applying electric field. growth not obvious when applied 0 – 10kV. But changes remarkably continues rise. error strengthen between simulation experimental is 43%.
