The Study on Paraffin-Water Emulsion PCM with Low Supercooling Degree

2013
This study aims to develop paraffin waxes based phase change material emulsion with low supercooling degree, which can be applied in a Thermal Energy Storage (TES) systems to maximize the use of natural heating and cooling sources via solar thermal collectors or evaporative coolers, and to raise the energy efficiency of the chillers operating at off ...

Development of a Novel Freezing-Levitation System for Producing Supercooled Droplet With Precise Control of Supercooling Degrees

Volume 1: Artificial Intelligence (AI) for Fluids; CFD Methods; CFD Applications; Bio-Inspired and Biomedical Fluid Dynamics; Fluid Measurement and Instrumentation; Energy & Sustainability
Abstract Supercooled droplets are important in atmospheric science, cryopreservation, and aviation safety due to their thermal and phase transition properties. Predicting icing and optimizing thermal management need understanding their cooling kinetics and surface interaction. Our innovative experimental approach uses acoustic levitation,

Supercooling of Water to -92{degrees}C Under Pressure.

Science (New York, N.Y.), 2010
The temperature at which "clean" supercooled water freezes has been determined as a function of pressure up to 3 kilobars, using a differential thermal analysis technique on subdivided water samples. The supercooling limit of such samples, -38 degrees C at normal pressure, is lowered by initial increase of pressure, reaching a minimum value of -92 ...

MOLECULAR WEIGHT DEPENDENCE OF CRYSTAL GROWTH RATE AND ITS DEGREE OF SUPERCOOLING EFFECT

Journal of Macromolecular Science, Part B, 2002
The molecular weight (MW) dependence of the linear crystal growth rate (G) and the influence of the supercooling on the relationship between MW and G at a given supercooling were studied for poly(ethylene succinate). The spherulite growth rate was measured over a wide range of temperature.

Effects of the degree of undercooling on flow induced crystallization in polymer melts

Polymer, 2004
This study investigates the coupled effects of mild shear flow and temperature on the crystallization behavior of two thermoplasticpolymers, namely, an isotactic polypropylene and an isotactic poly(1-butene). Rheological experiments are used to measure thecrystallization induction time under isothermal, steady shear flow conditions.
