当2D space设置为Axisymmetric Swirl时,求解器的坐标系依然为柱坐标系,但允许模型存在周向速度。 此时,求解器会自动对动量守恒方程进行周向补充,即 \frac{\partial}{\partial t}\left( \rho v_{w}\right)+\frac{1}{r}\frac{\partial}{\partial x}\left( r\rho v_{x}v_{w}\right)+\frac{1}{r}\...
圆柱坐标下轴对称问题选axisymmetric swirl,容易理解.对平面轴对称问题,Tutorial 4选择2D,而Tutorial 11选择axisymmetric,不知何故 相关知识点: 试题来源: 解析 真实问题都是三维的 如果某一维的变化可以忽略不计,则可以选用二维 直角坐标下,简化为二维,如果存在对称,可以设定对称边界条件 圆柱坐标下,如果可以忽略周向...
区别如下：General/2DSpace下有Planer、axisymmetric、axisymmetricswirl三种选项。在二维几何模拟中，某几何轴线可以设置成axis或者symmetry边界，则可以组成6种选项。以前，本人认为若几何是镜像对称时，如书本摊开，则会将轴选择成symmetry，2DSpace下选择axisymmetric；若是轴对称，如一个圆柱，则将几何轴线设置...
一个是平面对称，一个是旋转对称，上下对称的方形的通风口属于前者，拉瓦尔喷管属于后者，

New solutions for compact vortex rings and vortices in the presence of swirl and toroidal magnetic field are presented. Steady solutions are found for thin-core vortex rings, generalizing the classical results of Kelvin and Hicks. An exact family of steady spherical solutions is found in the case...
个人认为axisymmetric是二维的轴对称，而且在用这个的时候对称轴必须是X轴，而axisymmetric swirl是表示二维...
Laminar boundary layer in axisymmetric swirling ducted gas flowSeveral studies have been published [1–3] in which the authors solve the problem of the laminar boundary layer in an incompressible fluid on the walls of an axisymmetric duct in the presence of swirl in the outer flow. In [3],...
but what is c_u(), c_v(), c_w() in axisymmetric swirl 2d. how can I get the angular velocity in rad/sec (or tangential velocity). thanks cheers TS Can you please share the answer to this question. As u might hav already got it ...
Axisymmetric Swirl My boundary condition at the inlet is a Mass Flow Inlet. My problem is that I'm not able to find the place to set the swirl component at my inlet boundary condition. When I set the Flow direction, only the axial and radial component are used by starccm+ and the tan...
