Hi all,
I'm modelling a tidal turbine using the porous jump boundary condition. Does anyone know how to relate input parameters of the porous jump boundary condition (Face Permeability, Porous medium thickness and Pressure-jump Coeff.) with thrust coefficient? The next figure shows centerline Ux velocities along the domain for different Pressure-jump coeff. As the coeff. increases, velocity at disk decreases as expected, but downstream velocity recovers faster. Is this what I should expect?

You should find the formulas special for your problem in your references related to this process.
