Computational fluid dynamics

Full Text:

This graphic depicts the turbulent instability dynamics of large fire plumes, which have been modeled by Professor Paul DesJardin, Department of Mechanical and Aerospace Engineering, on the University at Buffalo’s Center for Computational Research’s computers using Large Eddy Simulation techniques. Instability dynamics are responsible for the unsteady heat transfer in fire environments, which have been observed experimentally. The mesh superimposed on the bottom of the plume is the underlying computational grid utilized to carry out the calculation. An improved understanding of instability dynamics will result in more accurate predictions of fire intensity and growth.
