What this dataset shows

This dataset observes condensation with acoustic and thermofluid sensors. Its visualizations show what the sensors measured inside the experiment.

Watch the recorded signal unfold

Condensation · inlet AE hit 60 · vapor quality 0.60 · 7.168 milliseconds from one acoustic-emission hit.

Measured channel 1
Condensation · inlet AE hit 60 · vapor quality 0.60. Waveform, frequency map and playback cursor use the same recorded channel. View original source

Time →

Read from left to right. The moving cursor connects the waveform and frequency map at the same moment.

Frequency ↑

Lower frequencies appear near the bottom of the map; higher frequencies appear above. A narrow bright band means power is concentrated in a small frequency range.

Color = relative power

Brighter colors show more power relative to the strongest part of this clip. Colors are not an absolute measure of loudness and should not be compared across datasets.

Listen to normalized sensor playback · 1,000× slower

Unmute the player to listen. The signal is centered and its volume is normalized for playback. This ultrasonic hit is slowed so that its changing pattern can be heard; the plots still show the original time and frequency. Playback volume is not calibrated sound pressure.

The published files contain sensor recordings rather than an optical movie of the condensing flow.

How this view was made

7,168 measured samples · 1,000,000 samples per second · channel 1 · original units: V.

The spectrogram uses a Hann window of 256 samples with 75% overlap. Colors show spectral power in dB relative to this clip’s peak, not calibrated sound pressure level.

Acoustic waveform, spectrogram and sonification share one clock. Optical-to-acoustic frame alignment is not established by the published preview metadata.

Acoustic video, spectrogram and waveform use the same measured samples. Optical recordings are shown separately; frame alignment with the acoustic clip is not established.

Acoustic data: replay, spectrograms and charts

Computed from this dataset's acoustic emission (AE) recordings at the condenser inlet, for three tests at an nPFH flow of 10.0 g/s, cooling water 25 g/s, vertical downflow and 18.9 psia. Nothing is simulated.
