摘要/Abstract

摘要： 为了探讨电水动力学强化沸腾传热机理,以水为实验工质,通过数值计算和实验观察相结合的方法,系统研究了冷态氮气泡在电场作用下的行为特性;并计算了直流电压10 kV工况下,气泡周围电场强度分布、气泡脱离周期和气泡脱离时刻瞬时速度场。结果表明:场强越大,气泡伸长变形越明显,脱离周期越短;电场强度沿着气泡轮廓方向逐步对称减小;气泡脱离时刻的速度随着电场强度的增大而增大且速度极大值处在气泡的底部。

Abstract: In order to discuss the mechanism of electrohydrodynamics enhanced boiling heat transfer,with water serving as the working medium the method combining numerical simulation with experimental study was used to research the behavior of cold nitrogen bubble under electric field.Numerical simulation was made for calculating the distribution of electric field intensity around the bubble,the cycle and instantaneous velocity when the bubble broke away under DC voltage 10 kV.The result showed that with increasing electric field intensity,the deformation of cold nitrogen bubble,i.e.,elongation was more obvious.The cycle got shorter when the bubble broke away.The electric field intensity gradually symmetrically decreased along the direction of the bubble outline.The velocity with which the bubble broke away increased with increasing electric field intensity and the velocity reached a maximum at the bottom of the bubble.

Key words: electrohydrodynamics, bubble, shape
