Heat exchangers with annular finned-tube type and partially wetted condition are utilized widely in engineering systems, such as air-conditioning systems refrigeration systems. In addition, the physical properties of fin materials should be considered functions temperature reality thus become a non-linear problem. Based on above two conditions, an optimal wet design problem, temperature-depende...

We dlscujs polymer adsorption in a poor solvent. For a single chain we find a wetting transition on an attractive wall when the thermal correlation length f is of the order of the adsorption length D If D is larger than f, for weak adsorption, the polymer chain partially wets the solid surface in the same way as a small liquid drop if D is smaller than f, strong adsorption, the chain forms a fl...

The Atmospheric Integrated Research and Monitoring Network (AIRMoN) of NOAA is a research program aimed at developing and implementing improved dry and wet deposition monitoring methodologies. For dry deposition, the array is built on the basis of air-surface exchange research stations, originally set up as the `CORE/Satellite Dry Deposition Inferential Methoda array under the National Acid Pre...

2014 Partially compatible binary mixtures of linear flexible polymers are considered in the presence of a wall which preferentially adsorbs one component. Using a Flory-Huggins type mean field approach, it is shown that in typical cases at two-phase coexistence the wall is always « wet », i.e. coated with a macroscopically thick layer of the preferred phase, and the transition to the non wet st...
