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.
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 |
