static calculate_dp(us_g, us_l, rho_g, rho_l, theta, eta_g, eta_l, sigma, d_tube, eps_g, l_cel)[source]

Calculate the pressure drop due friction and gravity based on various parameters.

Parameters:

  • us_g (float) – superficial gas flow velocity (m/s)

  • us_l (float) – superficial liquid flow velocity (m/s)

  • rho_g (float) – gas density (kg/m3)

  • rho_l (float) – liquid density (kg/m3)

  • theta (float) – Inclination of 1 cell (rad)

  • eta_g (float) – gas viscosity (Pa s)

  • eta_l (float) – liquid vicosity (Pa s)

  • sigma (float) – surface tension (N/m)

  • d_tube (float) – well diamater of 1 cell (m)

  • eps_g (float) – roughness of 1 cell (m)

  • l_cel (float) – length of 1 cell (m)

Returns:

  • dp_fric (float) – pressure drop due to friction (Pa)

  • dp_grav (float) – pressure drop due to gravity (Pa)
