Modeling Evaporative Cooling: A Coffee Cup Example Before setting up the COMSOL Multiphysics model, let’s consider the effects causing the cooling of the coffee as it evaporates. We assume a slight air draft around the cup (or beaker, since there is no handle in this case) that accelerates ...
Calculation of the oil-film water permeability from Eqs. (14)–(18) requires knowledge of the evaporative flux and the concentration driving force. Accordingly, the evaporation rate, water surface temperature, ambient temperature, and relative humidity must all be measured. Thus, to establish Dk, ...
Comparison of the calculation with the testing result is also provided. We have also drawn several conclusions, indicating the accuracy of the calculation. 展开 关键词: temperature field turbine generator evaporative cooling boiling heat transfer stator windings ...

For example, water may get blown off the evaporative media and escape the air system. The value entered here is a simple fraction of the water consumed by the cooler for normal process evaporation. The amount of drift is this fraction times the water evaporated for the normal cooling process...
To ensure the reliability of the optimization calculation program, we have validated the simulation program for this indirect evaporative cooling system by the Conclusions In this paper, after explicitly analyzing the irreversible heat and mass transfer processes in evaporative cooling systems, we ...

give us a moment to explain to you why we like this product. This product is not only portable and capable of cooling a large area, which we’ve already covered, but it’s also got some other features that we liked. For example, unlike some of the larger evaporative coolers, this one...
example of these processes. One such method that has gained recent favor is indirect evaporative cooling. This method minimizes/eliminates the need for energy intensive mechanical refrigeration. Some challenges of the indirect evaporative cooling process are fabrication of the evaporative cooling cell, ...
When the object to be coated has substantially the same cross sectional area at all levels of the coating liquid, only a single measurement or calculation of its cross sectional area need be made. In a processing tank for coating such an object, the position of one or more of the walls ...
