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

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