Mpemba effect - Wikipedia

He discussed the influence of stirring on the results of the experiment, noting that stirring the unboiled water led to it freezing at the same time as the previously-boiled water, and also noted that stirring the very-cold unboiled water led to immediate freezing. Joseph Black then discussed Fahrenheit's description of supercooling of water (although the term supercooling had not then been ...

Relaxation of Supercooling of Erythritol for Latent Heat Storage

The present paper shows experimental results on physical methods for supercooling relaxation of erythritol as a phase change material. Solidification behavior of erythritol melt was observed under the experimental conditions using the following 3 energy loadings: 1) ultrasonic irradiation, 2) stirring with seeding, and 3) agitation by bubbling. The obtained results have shown that supercooling ...

Superheating - Wikipedia

In physics, superheating (sometimes referred to as boiling retardation, or boiling delay) is the phenomenon in which a liquid is heated to a temperature higher than its boiling point, without boiling.This is a so-called metastable state or metastate, where boiling might occur at any time, induced by external or internal effects. Superheating is achieved by heating a homogeneous substance in a ...

Effect of Dissolution and Dispersion Conditions of VC-713 on the Hydrate Inhibition

In summary, the high-speed stirring and shearing effect promoted the dissolution and dispersion of VC-713 in the system, reduced the size of hydrated VC-713 molecular aggregates, increased the specific surface area of the aggregates, created a more complex network skeleton structure, and reduced the porous space size among the skeleton structures. Increasing the added amount of VC-713 to the ...
