An Examination of γ-valerolactone Ring Opening and Decarboxylation in Multiphase System and Over Various Solid Acid Catalysts
… liquid and gas phases over various catalytic systems aiming at improving the efficiency in selective preparation of target product. An initial attempt was made in a biphasic reactor to improve the yield to PEA catalyzed by mineral acids (H2SO4). A wide range of solvents was tested for their …

Phase field model for precipitates in crystals
… The traditional approach to simulate multiphase system is the sharp interface model. Sharp interface model requires tracking the interface between phases, which make the simulation much difficult and complicate. Phase-field model offers an alternative approach for predicting mesoscale …

Accurate fault location for power transmission lines
… is solved for the distance to fault. For multiphase systems the idea is 'generalised by using the theory of natural modes which involves the evaluation of eigenvalues and eigenvectors of the lines. In this way a multiphase system is decoupled into a number of single-phase modal circuits; …

Multiphase extensions to ODE models for detonations of non-ideal explosives
… approach of Watt et al., are extended to a multiphase system of equations. These multiphase equations, with realistic equations of state, are used to better capture the heterogeneities in non-ideal explosives used in mining applications. Streamline ODE multidimensional models are normally …

Recovery of crude oil from saturated porous media as a function of geochemistry and wetting-phase dynamics for multiple remediation flushing strategies
… the solid-liquid-liquid (S-L-L) junction for a multiphase system for three different API° gravity (or density) crude oils within aqueous solutions of varying pH and in contact with two different types of media including silica (glass plate) and limestone (calcium carbonate plate). Interfacial …

Study of micro-sized particle deposition using DEM, CFD-DEM and SPH approach
… A coupled CFD-DEM method is used to simulate the multiphase system. In the simulation liquid water film evaporates and leaves the particles at the container alone. Interesting patterns are seen to emerge as the liquid water film evaporates. The resulting packing structure analyzed in terms of the …

IMPROVED SEGMENTATION FOR AUTOMATED SEIZURE DETECTION USING CHANNEL-DEPENDENT POSTERIORS
… network (CNN) followed by an LSTM network. The multiphase model was evaluated on a blind evaluation set and was shown to detect 106 segment boundaries within a 2-second margin of error. Our previous best system, which delivers state-of-the-art performance on this task, correctly detected only 9 …

Experimental investigation of interfacial tension in two-phase system involving methane and water
… of hydrocarbon fluids involve dealing with the multiphase system. Viscosity and interfacial tension (IFT) are among the fluid properties that affect fluid behaviour. These properties have significant effects on fluid flow characteristics, and thus their importance in oil and gas production and …
