The rapid development of micro-thermal technologies has conveyed an increasing interest on convective boiling in micro-channels. Although there is general agreement that these systems may be able to dissipate potentially very high heat fluxes per unit volu ...
Some basic ideas of the heat transfer of ice slurries are discussed. The equations des-cribing a flow of a Bingham fluid through a tube with a heat flux over the boundary are presented. The theory shows that familiar Relations known in the field of heat ex ...

[1] CO2 exchange between lake water and the atmosphere was investigated at Toolik Lake (Alaska) and Soppensee (Switzerland) employing the eddy covariance (EC) method. The results obtained from three field campaigns at the two sites indicate the importance ...
This article presents experimental results of heat transfer from two different studies [1, 2] for horizontal flow boiling inside smooth copper tubes with different refrigerants. The main goal of this study was to verify the influence of the saturation temp ...
Heat flux measurements are very important in the study of the atmospheric boundary layer (ABL) dynamics; heat flux controls ABL stability and is therefore crucial to various topics such as air quality and hydrometeorology. Accurate heat flux measurements c ...
The current industrial need for compact high heat density cooling devices has conveyed an increasing interest on convective boiling in micro-channels. Although there is general agreement that these systems may be able to dissipate potentially very high hea ...
Local flow boiling heat transfer coefficients were measured for R-134a and R- 123 evaporating inside a microfin tube for horizontal flow and vertical upflow over a wide range of mass velocities, vapor qualities and heat flux. The objective was to study the ...
The flux of sensible heat from the land surface is related to the average rate of dissipation of temperature fluctuations in the atmospheric surface layer through the temperature variance budget equation. In many cases it is desirable to estimate the heat ...
As part of a comprehensive study on factors affecting flow boiling in horizontal tubes, local boiling heat transfer coefficients were measured for R- 134a evaporating inside the same 12.00 mm bore, plain tube for horizontal flow, vertical upflow and vertic ...
The conditional sampling formulation typically used in eddy accumulation flux measurements was tested at two sites using velocity, temperature, and specific humidity time series measurements. The first site was at Owen's Lake in southern California, and th ...
