Simultaneous Visualization of Density and Velocity Variations in a Stratified Shear Flow, Experiments in Fluids, 9, pp.107-109.


ABSTRACT
Two flow visualization techniques, the shadowgraph and the hydrogen bubbles, are combined to facilitate simultaneous observation of the vertical velocity profile and the density interfaces in a stratified mixed layer in an annulus. The experimental setup is described and some examples of the resulting photographs are presented and discussed.
