Temp-PLIFRecent studies have shown that the evaporation of water can induce surface tension gradients along the water surface that ultimately lead to a surface driven flow, known as Marangoni convection. To visualize and characterize the Marangoni convection in water, this study generated evaporation ...
The Grifton tower cam (courtesy of WITN) captured some pesky fog over Contentnea Creek and the Neuse River this morning. Notice it is mainly confined over water: the air temp is around 34° but the water temps are around 61-62°. The result is evaporation (or steam) fog.pic.twitter....
19.4.5.1 Water losses The rate of evaporation from a cooling tower is approximately 1% of the circulation rate for each 5°C drop in temperature across the tower, or about 7 l/h per tonne of refrigeration. Windage losses will obviously depend on the prevailing wind conditions and the design...

I'm simulating evaporation through a pipe. Water is flowing inside it and it gets heated with certain heat flux (1077328 W/m^2). It's subcooled water, it enters at 20°C and 2000 PSI, over a 16 m leght it must evaporate around 80% of the fluid. The thing is, I do ...
stirrer under the surface of waste water in an evaporation vessel and a blower above the surface; automatically supplying a fixed quantity of waste water to the vessel from a waste water supply tank; and sending air in a direction opposite to that of flowing waste water in the evaporation ...
摘要: A heat pump AC system is designed for the target vehicle.Evaporation/condensation temps are systematically studied.Impact of evaporation temp on air outlet temp is analyzed.Experiments test system performance compared with design performance parameters....

Thus, as the first approximation, it is advisable to study the evaporation characteristics of fire-extinguishing water-containing compositions in the temperature range up to 600 ◦C. Papers [12,13] presented the determined rates (and, accordingly, the typical durations) of high-temperature heating...
