Returns the advective flux of a fluid phase across the given sub-control volume face (corresponding to a pore throat).

Note: The flux is given in N*m, and can be converted into a volume flux (m^3/s) or mass flux (kg/s) by applying an upwind scheme for the mobility (1/viscosity) or the product of density and mobility, respectively.

El-Zehairy et al.(2019): Eq.(14): A0Q^2 + B0Q + C0 = 0 where Q is volumetric flowrate, A0 = [Kc + Ke] * rho /[2aij^2], Kc and Ke are contraction and expansion coefficient respectively, aij is cross sectional area of the throat, B0 = 1/K0 (K0 is trnasmissibility used in paper) and C0 = -deltaP In our implementation viscosity of fluid will be included using upwinding later. Thus, creepingFlowTransmissibility = mu * K0 and the volumetric flowrate calculated here q = mu * Q. Substitution of new variables into El-Zehairy et al.(2019), Eq.(14) gives: Aq^2 + Bq + C = 0 where A = A0 / mu^2, B = B0/mu = 1/creepingFlowTransmissibility and C = C0 attention: the q, volumetric flowrate, calculated here is always positive and its sign needs to be determined based on flow direction this approach is taken to prevent the term under the square root (discriminant) becoming negative

give the volume flowrate proper sign based on flow direction.
