Abstract

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.
