Contribution
It introduces a novel application of Schlieren imaging to capture the dynamic heat transfer processes in a confined liquid system.
Findings
Identification of different heat transport mechanisms
Time-resolved temperature field measurements
Insights into heat transfer dynamics in confined geometries
Abstract
This fluid dynamics video images the different heat transport mechanisms at play when a liquid confined in a vertical Hele-Shaw cell is heated from below. The two-dimensional time resolved temperature field inside the cell is measured by a quantitative Schlieren technique which is detailed in the video.
