The purpose of this report is to document a series of
numerical experiments performed to analyze strategies
for eliminating flame blow-down occurring in the Navy's
19F4 fire fighting training. The first strategy
involves the use of a fence in the way fences are used
as tennis court wind breaks. The second strategy
involves the use of fans to pressurize the space below
the propane burners. Numerical simulations were
performed for various fence heights, fence distances
from the platform and fan volume flow rates. These tests
confirmed that flame blow-down occurs when no action is
taken to prevent it and predicted that blow-down will be
reduced with the use of a fence and a fan.
