PyroSim / Simulation of evaporation LNG
« on: January 29, 2010, 05:00:38 am »
Hi everyone,

I'm trying to use this GUI of FDS.

I'm trying to simulate an evaporation of a mass of LNG (Liquefied Natural Gas). It's temperature is about -161°C.

I create a impound where the LNG could stay after the release from an ipotethic vessel.

I create, after, a vent surface with the characteristics of evaporaztion of the LNG (and obstruction relative to the impounding area).

The LNG, in real condition, when it reach the -85°C became gas with density below that of air.

So, how can I simulate this behaviour in Pyrosim? Why I can't see this behaviuor in SmokeView?

Every advice you could give make me very happy!!  ;D ;D

Thanks!!!
