This report describes the results of calculations that were performed using the Fire Dynamics Simulator (FDS) to examine the effect of wind on the thermal and fire conditions in a single-story residential structure and to provide a visualization of fire behavior representative of what members of the Houston Fire Department (HFD) experienced during the course of their interior operations, to provide insight on the thermal conditions that claimed the lives of two fire fighters during a wind-driven fire in a one-story ranch house on April 12, 2009, in Houston, Texas.
