For the incompressible flows, the Navier-Stokes equation could be written in the form:
There are two important issues regarding Navier-Stokes equations:
- Non linearity of momentum equations
- Pressure-velocity coupling
Segregated Solver
The solution scheme
- Solve Momentum equations (u,v,w)
- Solve pressure correction equation
- Correct fluxes and velocities
- Solve transport equations for other scalars
Coupled Solver
- Solve the Momentum equations- Pressure equation system in one go (u,v,w,p)
- Solve transport equations for other scalars
