Experimental Study on the Gas-Liquid Heat Transfer Enhancement under the Influence of Magnetic Field

摘要

A series of experiments of pool boiling are carried out and many groups of experimental data are obtained at different heat flux and magnetic strength. The results show that the greater magnetic strength is, the temperature rising rate of the sample increase appreciably with the magnetic field, and the longer the magnetization time is, that of the sample increases faster. The specific heat capacity of the water and oil and the viscosity of oil are decreased greatly. It is important for the area of energy engineering that magnetic field can intensify boiling. In order to analysis the thermal conduction disciplinarian of oil and water under the effect of magnetic field, the thermal conduction characteristics of oil and water without magnetic field is also contrasted. The research lays a foundation on exploring the mechanism of magnetic field enhancing boiling heat transfer and its practical application in engineering.
