Micro particle shadow velocimetry (mu PSV) is performed in the present study for simultaneous velocity measurement and interface tracking in both liquid-liquid and gas-liquid two-phase flows through circular microchannels of 5001 mu m diameter. The back-li ...
Phase equilibria in the CaO-Al2O3-Fe2O3-SO3 system have been studied, mainly at 1325 degrees C. In particular the solid solution compositions of ye'elimite Ca-4(Al6O12)SO4 and brownmillerite (C-2(A,F)) phases have been analysed and used to estimate the com ...
This study considers the prediction of the degree of asymmetry in the circumferential distribution of the liquid film in the tube cross section of horizontal annular gas-liquid two-phase flow, endemic of the lower region of this flow regime near the strati ...
A long lasting controversy on the nature of the reaction between liquid, Al and Al45Cr7 has been ended by planar front solidification experiments of Al-Cr alloy in a Bridgman furnace. Cr depletion in the liquid ahead of the quenched planar interface proves ...
Methods and materials for liquid encapsulation in thin (19 μm) silicone membranes are presented in this work. A set of 12 liquids including solvents, oils, silicone pre-polymers and one ionic liquid are experimentally tested. We show that all selected liqu ...
A numerical method for the solution to the density-dependent incompressible Navier-Stokes equations modeling the flow of N immiscible incompressible liquid phases with a free surface is proposed. It allows to model the flow of an arbitrary number of liquid ...
The rigidity temperature of a solidifying alloy is the temperature at which the solid plus liquid phases are sufficiently coalesced to transmit long range tensile strains and stresses. It determines the point at which thermally induced deformations start t ...
This research investigates the influence of alkali hydroxides on unrestrained volume changes. A detailed multi-method approach is used to characterize the progress of cement hydration, autogenous and drying volume changes (i.e., shrinkage), autogenous RH d ...
The simulation of the color optical properties of molecular dyes in liquid solution requires the calculation of time evolution of the solute absorption spectra fluctuating in the solvent at finite temperature. Time-averaged spectra can be directly evaluate ...
Despite the close association between tellurium (Te) and gold (Au) in many epithermal, orogenic, and intrusion-related hydrothermal ore deposits, the hydrothermal chemistry of Te remains poorly understood. We studied the protonation/ deprotonation and stru ...
