On the effective viscosity for the Darcy–Brinkman equation

Darcy's law can be expressed very generally as: where q is the volume flux vector of the fluid at a particular point in the medium, h is the total hydraulic head, and K is the hydraulic conductivity tensor, at that point. The hydraulic conductivity can often be approximated as a scalar. (Note the analogy to Ohm's law in electrostatics. The flux vector is analogous to the current density, head is analogous to voltage, and hydraulic conducti… WebThe City of Fawn Creek is located in the State of Kansas.
