Large-scale Generation of Patterned Bubble Arrays on Printed Bi-functional Boiling Surfaces

Creator:

Choi, Chang-Ho, David, Michele, Gao, Zhongwei, Chang, Alvin, Allen, Marshall, Wang, Hailei, and Chang, Chih-hung

Abstract:

Bubble nucleation control, growth and departure dynamics is important in understanding boiling phenomena and enhancing nucleate boiling heat transfer performance. We report a novel bi-functional heterogeneous surface structure that is capable of tuning bubble nucleation, growth and departure dynamics. For the fabrication of the surface, hydrophobic polymer dot arrays are...

Experimental Study of Nucleate Boiling Bubble Dynamics and Heat Transfer Enhancement on Printed Bi-functional Surfaces

Creator:

David, Michele

Abstract:

Boiling heat transfer is studied for its ability to dissipate high fluxes and achieve heat transfer coefficients two orders of magnitude greater than single-phase heat transfer systems. Heater surface enhancement with increased surface area, varied geometry, wettability contrast and micro/nano-structures can further enhance boiling heat transfer performance through bubble nucleation...
