Design and preliminary characterization of thermally-actuated pumps utilizing Marangoni and Leidenfrost effects

Creator:

Sedler, Stephen Joseph

Abstract:

Design and preliminarily characterization of two thermally-actuated pumps is presented in this thesis. The unique feature of both pumps is the presence of periodic asymmetrical structures on the channel walls. Two heat transfer effects are used with surface asymmetry to generate forces that drive the fluid in a preferential direction...

Passive pumping in pool and open channel configurations via meso-scale asymmetric surface patterning

Creator:

Strid, Logan

Abstract:

The research presented in this thesis is a continuation of collaboration between Oregon State University and Auburn University studying the feasibility of passively pumping liquid during boiling in a preferential direction using meso-scaled asymmetric surface patterns. Such a passive phase-change mechanism has great potential for thermal management in spacecraft and...
