I need to find the circulation for a flow in a pipe. I'm using the velocity in the angular direction (cylindrical coordinate system).
Am I right in thinking that an ideal vortex is one where there is no vorticity? That would mean there is no circulation. It's strange, because the velocity is...
Hello,
I'm thinking about a natural convection problem where you have turbulent flow on a vertical wall. It's compressible flow, and it's a two-phase problem. You have two boundary layers, one for the air-vapor mixture, and one for the condensate.
The question I'm pondering is this...
I think I may have figured it out. I'll use it and see how the results go.
I'm trying to have 3 separate PDE models, and activating each one in one of the subdomains.
Hello,
This is the first time I'm using COMSOL on a problem where I have multiple subdomains within the domain. Previously, I have only been using one domain/one set of equations/Two global sets of BC's.
I've been having a hard time thinking of a solution to my problem.
I have 3...
