Influence of spheroidal particle shape on particle size characterization by multi-wavelength light extinction method

open access: yesResults in Physics, 2018
In order to improve the applicability, spheroidal particles are substituted for the spherical particles in the traditional modeling of multi-wavelength light extinction method.

Two-phase Nonrepudiation Protocols [PDF]

open access: yesProceedings of the 7th International Conference on Computing Communication and Networking Technologies, 2016
A nonrepudiation protocol from party S to party R performs two tasks. First, the protocol enables party S to send to party R some text x along with a proof (that can convince a judge) that x was indeed sent by S. Second, the protocol enables party R to receive text x from S and to send to S a proof (that can convince a judge) that x was indeed received

Particle size distribution measurement based on ultrasonic attenuation spectra using burst superposed wave

open access: yesResults in Physics, 2019
In the characterization of particle size distribution (PSD) using ultrasonic attenuation method, the spectrum characteristics such as bandwidth or the number of frequencies is of great significance.

Two-phase galaxy formation [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2009
We propose and test a scenario for the assembly and evolution of luminous matter in galaxies which substantially differs from that adopted by other semianalytic models. As for the dark matter (DM), we follow the detailed evolution of halos within the canonical LCDM cosmology using standard Montecarlo methods.

On the Two-phase Fractional Stefan Problem [PDF]

open access: yesAdvanced Nonlinear Studies, 2020
Abstract The classical Stefan problem is one of the most studied free boundary problems of evolution type. Recently, there has been interest in treating the corresponding free boundary problem with nonlocal diffusion. We start the paper by reviewing the main properties of the classical problem that are of interest to us.

Modeling and Experimental Verification of the Electrical Efficiency for Variable-Frequency Rolling Piston Compressor under Variable Suction Conditions

open access: yesApplied Sciences, 2023
The frequency and the suction refrigerant state are complex in the actual operation of variable compressors, which leads to the variability of compressor performance under different operating conditions.

Two-Phase Equilibrium Conditions in Nanopores [PDF]

open access: yesNanomaterials, 2020
It is known that thermodynamic properties of a system change upon confinement. To know how, is important for modelling of porous media. We propose to use Hill’s systematic thermodynamic analysis of confined systems to describe two-phase equilibrium in a nanopore.

State of the Art on Two-Phase Non-Miscible Liquid/Gas Flow Transport Analysis in Radial Centrifugal Pumps-Part A: General Considerations on Two-Phase Liquid/Gas Flows in Centrifugal Pumps

open access: yesInternational Journal of Turbomachinery, Propulsion and Power, 2023
Gas–liquid mixtures are present in numerous industrial applications, such as in the process industry, oil production and transport with natural gas, deep-sea extraction, and irrigation. Any pump may have to carry multiphase flows.
