3.23 Recommended discretisation schemes

The following figures provide a summary and recommendations of discretisation schemes for different equations. We start with momentum conservation Eq. (2.49 ), described in Sec. 2.13 and Sec. 2.14 , for which accuracy is the main consideration in scheme selection.


Equation for a bounded property

The discretisation of an equation for a bounded scalar field is illustrated using the eqn equation from the k turbulence model (assuming constant eqn). Schemes are selected with an emphasis on boundedness.
