Pyrosim file - car fire

[Dominika Vandlickova]

Hello everyone, 

I do a simulation of an open car park and I need the fire to spread from one car to another. but it burns  only one car with low temperature and a very long time. Can anyone advise me how to set the parameters for a gasoline fire? I set up 1000 HRRPUA.

Thanks for help.

Hi,

Your model is set up so that combustion is governed by the material properties, yet your materials only have thermophysical properties. A simpler way would be to have the combustion governed manually (by the surface properties). All you need to do is set an ignition temperature and HRRPUA for the different surfaces.
