In this paper by applying the poloidal-toroidal decomposition of a velocity field, Oberbeck-Boussinesq equations are transformed into a new equivalent system.

本文利用速度场poloidal-toroidal分解，把Oberbeck-Boussinesq方程组转化为一个方程组。

Firstly, there are two types of winding patterns for toroidal vessel: spiral winding along toroidal vessel geodesics and analogous sine placement along the external surface of toroidal vessel.

首，环形容器型主要有两种类型：沿稳定测地螺旋和类似正弦外包罗铺放。
