Equation Type

Formulation

Continuity (Incompressible Fluid)

\(\nabla \cdot {\text{u }} = {\text{ }}0\)

Momentum (Navier-Stokes)

\(\rho {\text{ }}(\partial u/\partial t{\text{ }} + {\text{ }}u \cdot \nabla u){\text{ }} = {\text{ }} - \nabla p{\text{ }} + \mu \nabla ^{2} u{\text{ }} + {\text{ }}f\)

Species Transport

\(\partial C/\partial t{\text{ }} + \nabla \cdot \left( {u.C} \right){\text{ }} = \nabla \cdot (D\nabla C){\text{ }} + {\text{ }}S\)
