Experimental facility: CVE
Overview
HySafe partner: |
UNIPI |
Name: |
CVE |
Type: |
Vented room |
Scale: |
large scale |
Experiments: |
studies on vented explosions and effects of pressure outside the venting |
Technical details
Dimensions: |
2.8 m * 2.8 m * 3.2 m |
Temperatures: |
up to 120°C |
Pressure: |
up to 250 mbar overpressure |
Media: |
hydrogen-air and methane-air mixtures |
Special Features: |
the size of the chamber allow to simulate real ambient behaviours in case of explosion and to extrapolate the minimum safety value for the vent area as a function of expected hydrogen concentration |
Experiments - Equipment
Experiments: |
EXPERIMENTS: hydrogen-air atmospheres vented explosion with uniform or non uniform initial condition; some test variables are (1) vent area; (2) hydrogen concentration; (3) number and location of ignition points (we have eight different ignition points inside the CVE).
EQUIPMENT: 5 concentration analysers based on the variation of the thermal conductivity of the hydrogen-air mixtures as a function of hydrogen concentration; range: 0-20%vol.
1 Flow meter based on the heat conductivity; range: 0.3-16 l/s.
2 pressure transducer: piezoelectric; range 0-500mbar overpressure.
9 strain gauges for the measurement of the pressure outside the vent area.
3 thermo-resistances. |
