Cooling effect of sidewall-sprinklers
« on: December 14, 2010, 08:37:49 am »

Hi, back again :)

I wonder if anyone have sucessfully got "(sidewall) sprinklers to cool off heat flux on a wall? If I have heat-radiation from a fire in one building to another.
Is there a way to simulate this, or will there be (in later updates)?

In the FDS Technical Reference Guide, section 9.5.1 (Droplet Transport on a Surface) mentions the following:

"While attached to a surface, the ''droplet'' is assumed to form a thin film of liquid that transfers heat to the solid, and heat and mass to the gas."

From that I gather that it should work, as long as your wall isn''t a boundary condition (like a heater). But I''ve never made a model that uses that feature.
