摘要
The electric field enhancement of natural convection and pool boiling heat transfer on a plate surface immersed in ether was investigated.The experimental data indicated that electric field could enhance natural convection and pool boiling heat transfer.The enhancement effect of electric field on natural convection heat transfer was larger than the effect on pool boiling heat transfer.For natural convection heat transfer on plate surface immersed in ether,the enhancement effect of electric field gradually increased as voltage rose and decreased with increasing heat flux.For pool boiling heat transfer on plate surface immersed in ether, the enhancement effect of electric field gradually increased as voltage rose at heat flux q=5—9 kW·m-2.At the other testing heat flux(q≥10 kW·m-2), the increase of pool boiling heat transfer coefficient by applying electric field was much less.In the experimental condition, the enhancement effect of electric field on pool boiling heat transfer decreased with increasing heat flux.
The electric field enhancement of natural convection and pool boiling heat transfer on a plate surface immersed in ether was investigated. The experimental data indicated that electric field could enhance natural convection and pool boiling heat transfer. The enhancement effect of electric field on natural convection heat transfer was larger than the effect on pool boiling heat transfer. For natural convection heat transfer on plate surface immersed in ether, the enhancement effect of electric field gradually increased as voltage rose and decreased with increasing heat flux. For pool boiling heat transfer on plate surface immersed in ether, the enhancement effect of electric field gradually increased as voltage rose at heat flux q=5-9 kW · m^-2. At the other testing heat flux （q≥10 kW · m^-2 ）, the increase of pool boiling heat transfer coefficient by applying electric field was much less. In the experimental condition, the enhancement effect of electric field on pool boiling heat transfer decreased with increasing heat flux.
