In Solidworks Flow Simulation we can select a Friction Coefficient to be seen, where can I find information on how is calculated?
It is Darcy or Fanning coefficient or non of them?
all I can find in the knowledge base:
The solver uses the friction law based on the uniform sand roughness (Nikuradse roughness). For this type of roughness, the friction loss coefficient does not depend on the relative roughness height for low Reynolds numbers.
Mike Pogue also produced simplified expressions in relation between roughness and friction coefficient
