Thermal Response of Multi-Microchannel Evaporators During Flow Boiling of Refrigerants Under Transient Heat Loads With Flow Visualization

John Richard Thome, Navid Borhani, Houxue Huang

Multi-microchannel evaporators with flow boiling, used for cooling high heat flux devices, usually experience transient heat loads in practical applications. These transient processes may cause failure of devices due to a thermal excursion or poor local co ...

High variability in cross-shore thermally driven exchange

Hugo Nicolás Ulloa Sánchez

The variability of cross-shore thermally driven exchange was examined using ensemble averages of observations from the Kilo Nalu Observatory on the south shore of Oahu Hawaii. The cross-shore vertical shear, top-bottom temperature difference, and cross-sho ...

Experimental flow boiling heat transfer in a small polyimide channel

John Richard Thome, Manuel Gómez Marzoa

New experimental flow boiling heat transfer results averaged along a very low thermal conductivity polyimide channel are presented. The experimental setup consists of a horizontal, 285 mm-long, 2.689 mm inner diameter polyimide tube, heated by a counter-cu ...

Observation of extreme phase transition temperatures of water confined inside isolated carbon nanotubes

Kumar Varoon Agrawal

Fluid phase transitions inside single, isolated carbon nanotubes are predicted to deviate substantially from classical thermodynamics. This behaviour enables the study of ice nanotubes and the exploration of their potential applications. Here we report mea ...

Commissioning of HTS Adapter and Heat Exchanger for Testing of High Current HTS Conductors

Pierluigi Bruzzone, Kamil Sedlák, Davide Uglietti, Boris Stepanov, Rainer Wesche

In the EDIPO test facility, superconducting cables with a current carrying capacity up to 100 kA can be tested in a background field of 12.5 T. A NbTi transformer, operated at ???4.5 K, provides the sample current of up to 100 kA. The high-temperature supe ...

Distributed Sensible Heat Flux Measurement for Wireless Sensor Networks

Michael Lehning, Wolf Hendrik Huwald, Chad Higgins, Tristan Jonas Brauchli

The sensible heat flux component of the surface energy balance is typically computed using eddy covariance or two point profile measurements while alternative approaches such as the flux variance method based on convective scaling has been much less explor ...

The influence of water table depth and the free atmospheric state on convective rainfall predisposition

Gabriele Manoli, Sara Bonetti, Gabriel George Katul

A mechanistic model for the soil-plant system is coupled to a conventional slab representation of the atmospheric boundary layer (ABL) to explore the role of groundwater table (WT) variations and free atmospheric (FA) states on convective rainfall predispo ...

Seasonal Spatial Patterns of Surface Water Temperature, Surface Heat Fluxes and Meteorological Forcing Over Lake Geneva

David Andrew Barry, Ulrich Lemmin, Damien Bouffard, Abolfazl Irani Rahaghi

In many lakes, surface heat flux (SHF) is the most important component controlling the lake’s energy content. Accurate methods for the determination of SHF are valuable for water management, and for use in hydrological and meteorological models. Large lake ...
