AB - We present simultaneous two-dimensional velocity and scalar concentrations measuredon a central vertical plane in a turbulent plume. We use an edge-detection algorithm todetermine the scalar plume edge, and compare the data obtained in both a fixed Eulerianframe and relative to local plume coordinates defined in terms of the instantaneous plumeedge. We observe that the time-averaged distributions of vertical and horizontal velocityare self-similar. Measurements in the plume coordinate show that there is significantvertical flow outside the edge of the plume, contrary to the classical notion of purelyhorizontal velocities at the plume edge. We observe large variations in the plume widthand reason these to be due to the passage of large coherent eddies. The flow within theplume and in the nearby ambient fluid depends on whether an eddy is present or absent.When an eddy is present and the plume is wide, the vertical velocities near the plume edgeare small, but in regions where the plume is narrow and there is no eddy, large verticalvelocities are observed outside the plume.
