Abstract:
Turbulence models are often used to analyze practical
fires due to the computational intractability of fully
resolved three-dimensional time-dependent simulations of
practical buoyant turbulent flows. Developing reliable
turbulence models, however, has been inhibited due to
the absence of measurements; therefore, the objective of
the present investigation is to complete measurements
within round buoyant turbulent plumes, emphasizing
self-preserving conditions far from the source. Present
considerations include classical similarity concepts and
turbulence models of varying complexity.
