Steadiness of dilute, particle-laden density currents

Steadiness of dilute, particle-laden density currents

Author:

We conducted experiments to examine how steadiness-unsteadiness of source parameters is reflected in density currents in air. We ran experiments with other wise steady supply broken by two intervals (e.g. 30-10-30-10-30, or 30-5-30-5-30, where currents were supplied for 3 intervals of 30 s separated by 10 or 5 second pauses). 

Experiments were monitored using orthgonal laser sheets, with video data recorded in the streamwise vertical and horizontal planes; data have been orthorectified and processed for turbulent timescales and Feature-tracking-velocimetry velocity fields. Temeprature data were recorded at 3 Hz using 0.001" K-type thermocouples.
