Measurement and Correlation of the Viscosity of 1,1,1,2,2,4,5,5,5-Nonafluoro-4-(trifluoromethyl)-3-pentanone.

perfluorooctanoic acid (PFOA) and perfluorooctane sulfonate (PFOS) are man-made, perfluorosurfactants stable. The properties of perfluoroalkylated compounds that cause them to persist in the environment are also properties that make them attractive compounds for industrial use for more than 50 years. Because of the unique properties of carbon-fluorine bond and polarity perfluoroalkyl group, a potential successor to replace perfluorinated surfactants in many cases continue to perfluoroalkyl-based.

Exponential vaporization fronts and critical heat flux in pool boiling.

Here we study the beginning and propagation of the front evaporation and the transition to the critical heat flux (CHF) and the film boiling regime triggered by a steep, almost instantaneous increase in the release of heat from the heater is submerged lines Novec 7300 fluid. Propagation path resulting evaporation front along the strip heater is measured and proven to increase exponentially in time, the […]
