why do we need Cp for actuationDiskSource?

Hi All,
The actuationDiskSource model in OpenFoam requires both a thrust (Ct) and power (Cp) coefficient to calculate the velocity induction factor a=1-Cp/Ct to calculate the thrust resisting the flow. I am interested in simply applying resistance to the flow (Ct) and calculating the resultant Cp. Is there a good reason as to why the thrust force cannot be found through T=1/2 rho U^2 A Ct ? Why do we need Cp in the actuationDiskSource source? Is it possible to simply apply a Ct to the flow and calculate Cp? Many thanks, Tom Waits |
