Flow Visualization with CorVue

Boundary Interaction in Stratified Crossflow
Ambient density stratification can cause boundary interaction as shown here by a buoyant jet trapping and density current formation in density stratified crossflow.

Boundary Interaction in Stratified Ambients with Upstream Density Currents
This experiment shows ambient density stratification causes near-field flow trapping and subsequent density current formation for a single port discharge in a stagnant ambient.
CorVue S5 flow classification visualization shows a near-field flow trapped by stratified crossflow, buoyant density current upstream spreading, and subsequent far-field mixing (enhanced image).
