Detailed Description

This boundary condition provides a pressure condition, obtained from a zero-D model of the cylinder of a syringe.

The syringe cylinder is defined by its initial volume, piston area and velocity profile specified by regions of constant acceleration, speed and deceleration. The gas in the cylinder is described by its initial pressure and compressibility which is assumed constant, i.e. isothermal expansion/compression.

Usage
Property Description Required Default value
Ap syringe piston area [m2] yes
Sp syringe piston speed [m/s] yes
VsI initial syringe volume [m3] yes
tas start of piston acceleration [s] yes
tae end of piston acceleration [s] yes
tds start of piston deceleration [s] yes
tde end of piston deceleration [s] yes
psI initial syringe pressure [Pa] yes
psi gas compressibility [m2/s2] yes
ams added (or removed) gas mass [kg] yes

Example of the BC specification: 

    <patchName>
    {
        type            syringePressure;
        Ap              1.388e-6;
