3 lambdas
PO.VFP.PoettmannCarpenter.dPdL.SI(Ql, Qg, P, Rho_l, Ul, Bl, Rho_g, Ug, Bg, IFT_gl, Rs, pipe_ID, pipe_roughness)
Calculates pressure gradient using Poettmann-Carpenter (1952), [kPa/m]. Historical no-slip method for high-rate dispersed bubble flow (SI units).
PO.VFP.PoettmannCarpenter.Pout.SI(Ql, Qg, P_in, T, Rho_l, Ul, SG_gas, IFT_gl, pipe_ID, pipe_length, pipe_roughness)
Calculates outlet pipe pressure using Poettmann-Carpenter (1952), [kPa]. No-slip method. Gas properties (ρg, μg, Bg) use DAK (Z-factor) and LGE (viscosity) (SI units).
PO.VFP.PoettmannCarpenter.Pin.SI(Ql, Qg, P_out, T, Rho_l, Ul, SG_gas, IFT_gl, pipe_ID, pipe_length, pipe_roughness)
Calculates inlet pipe pressure using Poettmann-Carpenter (1952), [kPa]. No-slip method. Gas properties (ρg, μg, Bg) use DAK (Z-factor) and LGE (viscosity) (SI units).
