For this BC the User specifies:

  • The Pressure drop vs volumetric flow rate table (fan curve) as a CSV file upload.

The sample CSV file for a FanPressure is shown by the figure below: The fan curve is a table which links the pressure change to the averaged velocity through the fan. In the sample shown, ‘column 1’ is the ‘flow-rate‘ and ‘column 2’ is the ‘pressure values‘.
