Abstract: This paper systematically analyzes the cyclone gas flow field in the separating column of a circumfluent circulation cyclone separator based on the Navier-Stokese equation and the continuity equation of ideal flow under columnar coordinates. The Adomian decomposition-inverse operator method was used to solve the flow field. The basic representations of radial velocity, tangential velocity and axial velocity of the ideal flow in the separating column were derived, and computation values were compared with experimental values The mathematical model and computation equations were proved to be reasonable.

摘要： 由柱坐标系下的Navier-Stokes方程出发，建立了环流循环除尘系统分离柱内旋风流场的数学模型，利用对求解非线性微分方程非常有效的Adomian分解法——逆算符方法对流场进行求解，给出了三维流速(径向、切向和轴向)的解析表达式。
