Pollution fog formation
We have studied the effect of gaseous pollutants on fog droplet growth in heavily polluted air using a model that describes time-dependent sulfate production in the liquid phase and thermodynamical equilibrium between the droplets and the gas phase. Our research indicates that the oxidation of SO 2 to sulfate has a significant effect on fog 5 droplet growth especially when hygroscopic trace gas...
متن کاملFormation of ice lenses and frost heave
[1] I examine the morphology of ice growth in porous media. Intermolecular forces cause premelted fluid to migrate and supply segregated ice growth (e.g., lenses) and frost heave. I account for the net effect of these microscopic interactions in a homogenized model formulated in terms of fundamental physical properties and characteristics of the porous medium that can be measured; no ad hoc par...
متن کاملExperimental Evaluation Of The Frost Formation
Frost formation on an evaporator causes significant problems by decreasing inlet air flow. It is important for a precise prediction to understand the dominant factor of the frost formation. In this paper, the frost layer on the cold plate is experimentally obtained with different velocities while maintaining a surface temperature at -20 degrees Celsius. The mass and height of the frost layer is...
متن کاملFrost flower formation on sea ice and lake ice
[1] Frost flowers are clusters of ice crystals found on freshly formed sea ice and occasionally on frozen lakes. They belong to a class of vapour-related phenomena that includes freezing fog, hoar frost and dew. It has hitherto been supposed that they form by condensation from a supersaturated atmosphere or from water wicked up through porous sea ice. Here we show that they can form on solid, p...
متن کاملsimulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water
abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...
