Numerical Model of Electrostatic Field in Electrostatic Charged Spray

摘要: 静电喷雾植保机具使用多种形式的充电电极,不同形式的电极产生不同的充电电场,直接影响通过电场的雾滴或粒子的荷电量及相应的荷电两相流动,从而直接影响静电植保喷雾机的性能。该文建立了环状电极充电电场的数学模型,及其勒让德函数解。

Abstract: Several kinds of electrode shape are used in electrostatic charged spray. They directly affect particle charging and the relevent two phase flow behavior. Numerical model of the electrostatic field of a circular electrode is established. Its Legendre function solution and calculated results are obtained.
