DISCHARGE OF SATURATED WATER THROUGH PIPES AND ORIFICES
Аннотация
Saturated or subcooled water up-to 8 kg/cm2
pressure was discharged to atmosphere from a pressure
vessel through pipes of 4 mm ID by 0 - 2500mm
long. Flow rates, flow patterns and pressure profiles
along both long and short pipes were measured.
Flow patterns of flashing water in a glass tube were
observed by high speed camera. Results were as following.
The pressure gradient at the exit of long
pipe was finite and the pressure along the short
pipe was constant. The flow pattern upstream of the
pipe exit was "froth flow".
