Steadiness of dilute, particle-laden density currents

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).
