Predicting fire behavior in nonuniform fuel arrays is a problem re- 

 quiring: (1) a method of assessing fuel nonuniformity , (2] a method 

 of simulating fuel nonuniformity, and (3) an algorithm governing fire 

 spread through a simulated array. The bulk fuel properties (load, 

 depth, average particle size, etc.) are partitioned into a honeycomb 

 array. An algorithm simulates fire spread through the array by 

 coupling predictions of heat flowing from a burning cell to predic- 

 tions of the heat required for ignition of its adjacent cells. 

 Multiple results of fire behavior are displayed as distributions 

 in contrast to previotisly generated singular values. Methodology is 

 emphasized. 



KEY WORDS: fire behavior, nonuniform fuel, nonuniform fire, fire 

 spread, fire intensity.
