Predefined sprinklerheads

[Emiel van Rossum]

Hi all,

I regualy have to simulate with sprinklers, but i am not a sprinkler
expert.

Do you guy's have a set of predefined sprinklerheads or something like
that?

Best regards,

Emiel

Well, it's not so simple. You should know what you want your sprinkler
system to achieve, and how it is actiavated. Just putting in some
random sprinkler head is going to give unusable results.

garbage in, garbage out.

It should also be noted that there is currently little to no
validation basis for the suppression effects of water in FDS.
Sprinkler activation has some validation, large drop movement (i.e.
bucket test like simulations) has some validation provided one has
measured that flow pattern for the specific nozzle being simulated.

The best information on the sprinklers can be found on the internet
sites of the manufacturers. Here in Germany: Minimax and Total.
I looked into the application of FDS to real world problems but this
issue seems to be closed: Sprinklers are pretty standardized and the
design is made by special programs here in Germany: Input is geometry
and thermal loads and output is the complete design including ordering
list and installation plans.
