The objective is to know the distribution of explosive cloud formed from leaking propane through a pressurized cylinder. & to determine maximum flammable cloud formed from it.
Study will be done in two phases:
1) Transient CFD simulation of propane leak and formation of flammable cloud.
2) Transient FSI simulation of explosion of the flammable cloud coupled with the response of the partition plate.
A transient CFD simulation of the is performed and the flammable cloud tracked in time. The inside of the propane cylinder itself is not modeled, but the cylinder pressure adjusted to the quantity of leak.
Due to high density of propane, it is coming down from leak location and is distributed over the ground.
Over time, the leaked propane sustains sufficient momentum coming out, and therefore spreads slightly away from the OXCE unit.
With this propane distribution, the maximum explosive cloud volume is observed is 6.4 m3 within the flammable limits of propane
This maximum explosive cloud volume of propane attained in duration of 17.5 seconds after commencing of leak.
