Experimental study of two-phase gas-liquid flow in a microscale fractal-like branching flow network

Creator:

Kwak, Younghoon

Abstract:

Two-phase gas-liquid flows in microscale fractal-like branching channel flow networks were experimentally studied to assess the validity of existing void fraction correlations and flow regimes based on superficial gas and liquid velocities. Void fractions were assessed using two different methods. First, void fraction data were acquired using a High-Speed-High-Resolution (HSHR)...

Dissertation
Microscale thermal management utilizing vapor extraction from a fractal-like branching heat sink

Creator:

Apreotesi, Mario A.

Abstract:

It is hypothesized that increases in pressure drop due to vapor generation during boiling in microchannels can be reduced by extraction of vapor at its point of inception. Ultimately, this local vapor extraction decreases the pressure drop required to drive the flow through a fractal-like branching, microchannel flow network within...

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...

Microscale thermal management using membrane vapor extraction

Creator:

Apreotesi, Mario A.

Abstract:

With the miniaturization of microelectronics and increase of processor speeds in the last few decades, thermal management is drastically affecting overall packaging and system capabilities. Due to the special needs introduced, research focusing on microscale cooling has increased. This study combines the positive characteristics of single- and two-phase flows in...
