Hi, I have built a simple solar chimney model with a passive vortex generator with reference to https://www.sciencedirect.com/science/article/pii/S096014812100032X and https://www.comsol.com/forum/thread/attachment/62739/models.mems.fluid_structure_interaction-10017.pdf
Questions: 1. Is there a document guide to using the Turbulence flow k-E with a simple example? 2. How can I add a constant heat flux to one wall of my structure? 3. Can someone please guide on what is the suitable range of values for Thermal Conductivity k_iso and Heat Capacity at constant pressure Cp for (i) an elastic winglet (Vortex Generator) with below values
- Property Variable Value Unit Property group
- Young’s modulus E 2e5 Pa Basic
- Poisson’s ratio nu 0.33 1 Basic
- Density rho 7850 kg/m³ Basic
(ii) Rectangular Chimey
- Property Variable Value Unit Property group
- Density rho 1e3 kg/m³ Basic
- Dynamic viscosity mu 1e-3 Pa·s Basic
I am trying to generate Temperature variation along the absorber surface for different time instances
Thanks in advance!
