Интенсификация теплообмена в миниканалах под воздействием электрического поля

Abstract

The influence of the heat flux density and electric field on heat transfer during pumping of a dielectric liquid in mini-channels is studied. It is established that with an increase in the heat flux, the heat transfer coefficient increases in the entire studied range of voltages on the electrodes. The strongest influence of the field on heat transfer is observed at low heat flux densities. The electric field acts both on the vapor bubbles and on the dielectric liquid, thus changing the hydrodynamics of the liquid motion and, consequently, the intensity of heat transfer. Generalization of experimental data is carried out, good agreement between experimental data and those calculated from analytical dependences is shown. The results of the study can be used in the design of cooling systems for various purposes.
