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

\( p_p \)	=	incompressible pressure at patch [m2/s2]
\( p_0 \)	=	incompressible total pressure [m2/s2]
\( U \)	=	velocity

2. compressible subsonic:

\[ p_p = p_0 - 0.5 \rho |U|^2 \]

where

\( p_p \)	=	pressure at patch [Pa]
\( p_0 \)	=	total pressure [Pa]
\( \rho \)	=	density [kg/m3]
\( U \)	=	velocity

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

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

where

\( p_p \)	=	pressure at patch [Pa]
\( p_0 \)	=	total pressure [Pa]
\( G \)	=	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

\( p_p \)	=	pressure at patch [Pa]
\( p_0 \)	=	total pressure [Pa]
\( \gamma \)	=	ratio of specific heats (Cp/Cv)
\( \psi \)	=	compressibility [m2/s2]
\( G \)	=	coefficient given by \(\frac{\gamma}{1-\gamma}\)

The modes of operation are set by the dimensions of the pressure field to which this boundary condition is applied, the psi entry and the value of gamma:

Mode	dimensions	psi	gamma
`incompressible` subsonic	p/rho
`compressible` subsonic	p	none
`compressible` transonic	p	psi	1
`compressible` supersonic	p	psi	> 1

Usage

Property	Description	Required	Default value
`U`	Velocity field name	no	U
`phi`	Flux field name	no	phi
`rho`	Density field name	no	rho
`psi`	Compressibility field name	no	none
`gamma`	(Cp/Cv)	no	1
`p0`	Total pressure	yes

Example of the boundary condition specification:

    <patchName>
    {
        type            totalPressure;
        p0              uniform 1e5;
    }
