Recent attempts to model the flow in very hot fire plumes where radiative transport of heat may significantly modify both the dynamics of the flow and the processes of combustion have met with only partial success. This paper gives an account of a model for the flow in a…

To trully allow fires to play their natural role in wilderness ecosystems, it is sometimes necessary to have large fires of long duration. Large fires are ecologically significant events that drive many other ecosystem processes. However, these fires pose significant management…
