是否可以使用 OpenModelica 标准库对浸入流体腔中的管道进行建模?
我想对浸入流体腔中的管道进行建模,以研究两种流体之间的传热。我通过使用连接到同一 WallConstProp
的两个 DynamicPipe
对此进行建模,但我不确定这是否是正确的建模方法。我的问题是:MSL 中是否有可用的特定组件来对此类配置进行建模,或者我应该查看其他库吗?
此致, 马克西姆
I would like to model a pipe immersed in a fluid cavity to study the heat transfer between the two fluids. I modeled this by using two DynamicPipe
connected to the same WallConstProp
but I'm not sure it is a correct way to model it. My question is : is there a specific component available in the MSL to model such a configuration or should I look in other libraries ?
Best regards,
Maxime

据我所知,Modelica 标准库中没有这样的用于将管道传热到周围流体的组件。如果您只需要与壁内流动正交的传热,那么最好的假设是使用通过传热连接的管道对两种流体进行建模。您可以基于努塞尔相关性等创建自己的传热模型,以便对第二根管道到周围流体的传热进行建模。
MSL 提供基本组件,为所有 Modelica 用户提供共同基础,并作为起点。特定的商业或开源库可以覆盖特定的应用程序。
There is no such component for the heat transfer of a pipe to a surrounding fluid in the Modelica Standard Library as far as I know. If you only need heat transfer orthogonal to the flow in the wall then it is a good assumption to model both fluids with a pipe connected via a heat transfer. You can create your own heat transfer model based e.g. on a Nusselt correlation in order to model the heat transfer to a surrounding fluid for the second pipe.
The MSL offers basic components to provide a common basis for all Modelica users and works as a starting point. Specific applications can be covered by specific commercial or open source libraries.
