Resistance Loss Coefficient
Hello,
can someone tell me how to calculate the "Resistance Loss Coefficient" and/or the "Linear Resistance Coefficient" for use in the CFX Porosity Settings Tab? Found nothing on the web unfortunately, so thanks a lot in advance! 
You use the coefficients to match a porous medium to experimental results. Do youy have experimental results?

make use of you experiment data of pressures and velocities. you can refer the equation 1.146 in ANSYS CFXSolver Theory Guide, at page 33. then you can obtain Kperm and Kloss via your experimental data. you can contact me if you like, because i just studied that days ago.

what i have are the laminar and turbulent permeabilities k1 and k2 which correspond to this equation:
dP/L = mu/k1 * U + rho/k2 * U^2 Looks similar to the equation in Solver Theory Guide, but are these the values I need? Thank you so far! 
Hi Gentlemen,
I am on the process of calculating the Linear & Quadratic loss coeff. Via experimental Data (V vs P) but the equation im getting from the graph is giving a negative () Value for permeability. Please Help me remedy this problem. Thank you very Much. will
