Temperature index melt modelling in mountain areas
Temperature index or degree-day models rest upon a claimed relationship between snow or ice melt and air temperature usually expressed in the form of positive temperatures. Since air temperature generally is the most readily available data, such models have been the most widely used method of ice and snow melt computations for many purposes, such as hydrological modelling, ice dynamic modelling...
متن کاملChemical Interaction of Ferric Oxide with Sodium Sulfate at High Temperature Relevant to Hot corrosion
The studies include the results and discussion related with reaction of Fe2O3 with Na2SO4 in presence of SO2 (g) at 800 and 900 C. The iron oxides are produced by the oxidation of iron base alloys in many industrial operations. The metal oxide undergoes certain high temperature chemical reactions in presence of a gas (such as SO2) and molten salts (say Na2SO4). The thermo-gravimetric studies h...
متن کاملSimultaneous prediction of ethylene content and melt temperature in melt-state polypropylene by near-infrared spectroscopy and chemometrics.
This paper reports on a simultaneous prediction method for ethylene (C(2)) content and the melt temperature in melt state random polypropylene (RPP) and block polypropylene (BPP) by near-infrared (NIR) spectroscopy and chemometrics. The NIR spectra of RPP and BPP in melt states were measured by a FT-NIR on-line monitoring system. The predicted values of the C(2) content from the RPP or BPP spec...
متن کاملThe Melt Shear Viscosity of Polypropylene/Glass Bead Composites at High Extrusion Flow Rates
The effects of filler content and its surface treatment with silane coupling agent on the melt shear viscosity of glass bead-filled polypropylene (PP) composites have been investigated using a capillary rheometer at a wide shear rate scope of 150 to 7200 s and temperature range of 160 to 200 C. The melt flow obeys power law, but the slopes of the flow curves have transitions at the shear rate o...
متن کاملFabrication of Melt Spun Polypropylene Nanofibers by Forcespinning
Melt spinning of polypropylene nonwoven nanofiber mats is demonstrated using Forcespinning The effects of rotational speed and melt flow rate of polymer on fiber diameter were studied. It was observed that melt flow rate of the polymer plays a major role in nanofiber formation and uniformity. Differential scanning calorimetry and X-Ray Diffraction analysis indicate that the crystallinity of nan...
