Simulation of Water Turbine with CFX
Hello everyone,
I am working on simulation of a water turbine with CFX. This is my first work in CFD. Type of turbine: Francis (radial runner). I have all the measured data in real turbine (net head, flow and output power). My doubt is: What are the best boundary conditions for inlet and outlet ? Example: Inlet Conditions: flow Outlet Conditions: pressure or Inlet Conditions: pressure Outlet Conditions: pressure I do not know with is the boundary conditions that ensures better results in simulation for efficiency and cavitation. Please, help me, every reply would be appreciated. Thank you very much. |
