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.
