Gradient Microstructures for Flow-Boiling Enhancement

International Journal of Heat and Mass Transfer, 2023
Herein, we apply grayscale lithography to produce novel gradient microstructures, demonstrating the enhancement of flow boiling through the manipulation of drag forces upon the forming bubbles. The use of engineered 3D anisotropy allowed directional control of boiling enhancement, with respective critical heat flux and peak heat transfer coefficient ...
