Coalescence of ultrasound contrast agent microbubbles is studied to prevent embolies [1] or to block tumour vessels. [2] Microbubble coalescence has been studied with the aid of high-speed photography. [3] In cloud physics the main mechanism of collision is the different terminal velocity between the droplets. The terminal velocity is a ...
In the Oil and Gas, Petrochemical and Oil Refining industries, liquid-gas coalescers are widely used to remove water and hydrocarbon liquids to less than 0.011 mW (plus particulate matter to less than 0.3 μm in size) from natural gas to ensure natural gas quality and protect downstream equipment such as compressors, gas turbines, amine or ...
In chemistry, coalescence is a process in which two phase domains of the same composition come together and form a larger phase domain. In other words, the process by which two or more separate masses of miscible substances seem to "pull" each other together should they make the slightest contact.
The collision and coalescence is not as important in mixed phase clouds where the Bergeron process dominates. Other important processes that form precipitation are riming , when a supercooled liquid drop collides with a solid snowflake, and aggregation, when two solid snowflakes collide and combine.
Coalescence (computer science), the act of merging adjacent free blocks of memory to fill gaps caused by memory deallocation; COALESCE, an SQL function that selects the first non-null from a range of values; Null coalescing operator, a binary operator that is part of the syntax for a basic conditional expression in several programming languages
Flocculation is the accumulation of drops within a continuous liquid phase. Creaming is the accumulation of drops at the top of a liquid continuous phase. Coalescence is the merging of two drops into one single drop. Demulsification is when the dispersed phase completely coalesces into one continuous phase.
The key step in cheese production is the separation of the milk into solid curds and liquid whey. This separation is achieved by inducing the aggregation processes between casein micelles by acidifying the milk or adding rennet. The acidification neutralizes the carboxylate groups on the micelles and induces the aggregation.
Surprisingly, some of these water-in-water emulsions can be exceptionally stable from coalescence for up to 30 days. Because molecules of liquid crystal assume a preferred common orientation among themselves, the overall orientation of liquid crystals in a droplet is only stable in certain configurations (Fig. 3).
