Detailed Description

This boundary condition provides a total pressure condition. Four variants are possible:

1. incompressible subsonic:

$p_p = p_0 - 0.5 |U|^2$

where

	=	incompressible pressure at patch [m2/s2]
	=	incompressible total pressure [m2/s2]
	=	velocity

2. compressible subsonic:

$p_p = p_0 - 0.5 \rho |U|^2$

where

	=	pressure at patch [Pa]
	=	total pressure [Pa]
$\rho$	=	density [kg/m3]
	=	velocity

3. compressible transonic (\gamma <= 1):

$p_p = \frac{p_0}{1 + 0.5 \psi |U|^2}$

where

	=	pressure at patch [Pa]
	=	total pressure [Pa]
	=	coefficient given by $\frac{\gamma}{1-\gamma}$

4. compressible supersonic (\gamma > 1):

$p_p = \frac{p_0}{(1 + 0.5 \psi G |U|^2)^{\frac{1}{G}}}$

where

	=	pressure at patch [Pa]
	=	total pressure [Pa]
$\gamma$	=	ratio of specific heats (Cp/Cv)
$\psi$	=	compressibility [m2/s2]
	=	coefficient given by $\frac{\gamma}{1-\gamma}$

The modes of operation are set via the combination of phi, rho, and psi entries:

Mode	phi	rho	psi
`incompressible` subsonic	phi	none	none
`compressible` subsonic	phi	rho	none
`compressible` transonic	phi	none	psi
`compressible` supersonic	phi	none	psi

Patch usage

Property	Description	Required	Default value
`U`	velocity field name	no	U
`phi`	flux field name	no	phi
`rho`	density field name	no	none
`psi`	compressibility field name	no	none
`gamma`	ratio of specific heats (Cp/Cv)	yes
`p0`	total pressure	yes

Example of the boundary condition specification:

    myPatch
    {
        type            totalPressure;
        U               U;
        phi             phi;
        rho             none;
        psi             none;
        gamma           1.4;
        p0              uniform 1e5;
    }

Note: The default boundary behaviour is for subsonic, incompressible flow.
