Scalar dissipation in a turbulent round jet
Abstract eng: Scalar dissipation is obtained in the self-preserving region of a free round turbulent air jet at high Reynolds number. Air is slightly heated and temperature is considered passive. Simultaneous laser Doppler velocimetryicold- wire thermometry measurements were used to balance the temperature variance equation budget. Special care was paid to the statistical convergence of third-order moments. Temperature dissipation was deduced from the budget and directly measured with parallel cold wire probes. The validity and limitation of two point scalar measurements are presented.
