Abstract:
Fire induced flows are of importance in a variety of
fire phenomena including entrainment, pollutant
formation, fire size and fire spread. A receipe
pioneered by Baum and McCaffrey at NIST utilizes the
distributions of heat release rates and vorticity in the
fire in the evaluation of the fire induced flow field.
In this work, we utilize mean mixture fraction
measurements and mean velocity measurements in the fire
to deduce these distributions. Using these
distributions in conjunction with the methodology, we
have calculated the flow field of a 7.1 cm natural gas
fueled buoyant flame. The results are in excellent
agreement with experimental data.
