Description🔗
The prghTotalHydrostaticPressure
is a boundary condition that provides
static pressure condition for p_rgh
, calculated as:
where:
Property | Description |
---|---|
\(p_{rgh}\) | Pressure: \(\rho g (h - h_{ref})\) [Pa] |
\(p\) | Hydrostatic pressure: \(\rho g (h - h_{ref})\) [Pa] |
\(h\) | Height in the opposite direction to gravity |
\(h_{ref}\) | Reference height in the opposite direction to gravity |
\(\rho\) | Density |
\(g\) | Acceleration due to gravity [m/s^2] |
Usage🔗
The condition requires entries in both the boundary and field files.
