MOLECULAR MIXING LENGTHS FOR TURBULENT WAKES
Abstract
A simplified analysis is performed of the turbulent mixing of a trace chemical species with the bulk chemical species. The general relationship between the mixing on a molecular scale and the concentration fluctuation intensity of the trace species is given. This is then applied to a turbulent wake, to determine the axial length that it takes for ingested gas to become mixed. The results are sensitive to the assumed turbulent dissipation rate; giving values of the mixing length from the order of the wake radius to two orders of magnitude larger.
