Submerged jet impingement boiling thermal management

Creator:

Cardenas, Ruander

Abstract:

Technologies such as avionics and power electronics are driving the demand for thermal management schemes towards high heat fluxes and low surface temperatures. Typically, these applications require the dissipation of heat fluxes in the rage of 100-1000 W/cm² while maintaining surface temperatures lower than about 85 °C. Phase-change heat transfer...

Dissertation
The weather pattern and trends associated with Gulf Stream turbulent heat loss events

Creator:

Loyd, Nicholas

Abstract:

The weather pattern and trends associated with heat flux events (HFEs) over the Gulf Stream (GS) are examined as part of the CLIMODE project. A large portion of GS turbulent heat loss occurs during distinct synoptic scale events with a duration of one to two days. Forty percent (40%) of...

Experimental study of subcooled water spray cooling using flow symmetric micro-structured surfaces

Creator:

Tulchinsky, Alex M.

Abstract:

Spray impingement cooling has been shown to be a leading candidate for future high heat flux cooling applications. In general, spray cooling curves consist of three heat flux regimes; single-phase, two-phase and critical heat flux (CHF). CHF is considered the design limit for almost all two-phase cooling applications, as a...

Thermal hydraulic analysis of the Oregon State TRIGA Reactor using RELAP5-3D

Creator:

Marcum, Wade R.

Abstract:

Oregon State University has recently conducted a complete core conversion analysis as part of the Reduced Enrichment for Research and Test Reactors Pprogram. The goals of the thermal hydraulic analyses were to calculate natural circulation flow rates, coolant temperatures and fuel temperatures as a function of core power for both...
