Does heat travel differently in tight spaces?
Green-tinted image showing thermal plumes in a Hele-Shaw cell, illustrating heat transfer in confined spaces.

Hugo Ulloa and Daisuke Noto of the School of Arts & Sciences have unearthed findings that address long-standing mysteries in the mechanics of fluids in confined, tight spaces: how their boundaries affect heat as it emanates from one place and dissipates throughout the space. The image above is a lab-scale hydrothermal system modeled utilizing a Hele-Shaw cell of 10 cm tall, 20 cm long and 4 mm gap. The interior of the Hele-Shaw cell is filled with degassed, deionized water heated from the bottom and cooled from above. A green laser sheet crosses the middle plane of the cell to visualize the motions of micro-scale particles seeded on the water, allowing researchers to estimate the fluid velocity and temperature.
