PARAMETERS Explosion simulations in a 1.2 m3-vessel using the CFD-software

FLUENT 6.1 have been performed Initially vessel is filled with propane (4.2% vol) in a quiescent

environment Ignition source is located on the vessel center line in a height of

0.74m (below vessel half-height) Vessel is filled with 0%, 50% & 100% AXS

Comparison Between Measurement Data & Simulation Results

Page 24: AXS Presentration number 2

Agreement between simulation results and experimental data concerning explosion pressure seems to be excellent Simulation serves as good indication for the behaviour of the gas mixture under different circumstances and allows

reasonable prediction of pressure, pressure rise and temperature

AXS Has Been Extensively Tested, Validated & Is Ready For ImplementationAXS Can Eliminate Any Tank Explosion Associated With:

The Use of Domestic & Commercial LPG Bottles
