Conditionally-sampled Estimates Of Turbulent Scalar Flux In A Simulated Fire

Crauford, N.L., Bray, K.N.C. and Moss, J.B., 1986. Conditionally-sampled Estimates Of Turbulent Scalar Flux In A Simulated Fire. Fire Safety Science 1: 185-196. doi:10.3801/IAFSS.FSS.1-185


ABSTRACT

A conditional sampling strategy is described in which temperature, measured by fine wire thermocouple, is used to trigger the acquisition of velocity data by LDA. The technique permits the determination of a range of scalar-velocity correlations, important to the development of flow field models, throughout a simulated buoyant fire. The experimental data is incorporated into flux estimates which permit the assessment of mass, energy and momentum balances in two distinctive, intermittently burning regimes in the buoyant flame.
