Hello everyone, hope you're doing well. I'm trying to simulate a Solar Chimney Power Plant in Comsol, and I'm a beginner in Comsol. If you can anyone send me an example to simulation of Solar Chimney Power Plant in Comsol
What fluids are you considering in your model? If it's air (I think), COMSOL has air in it's built-in materials. You just have to add it into your model when setting up your model. I suggest you visit COMSOL's website to learn more about model set up. Start with this tutorial https://www.comsol.com/model/flow-past-a-cylinder-97
If you know the properties of the fluid at a certain temperatures (such as water or air at 300K), you can either directly set the fluid from the material library or manually input the values of density, heat capacity etc on the material tab. Make sure you select the domain where the fluid flows.
