DEFORMATIONAL COMPATIBILITY FOR SOLID PHASE OF DENSE LIQUID-SOLID FLOW IN BEND PIPES

Continuum Approaches for Describing Solid-Gas and Solid-Liquid Flow

Two-phase continuum models have been used to describe the multiphase flow properties of solid-gas and solid-liquid mixtures. The approach is limited in that it requires many fitting functions and parameters to be determined empirically, and it does not provide natural explanations for some of the qualitative behavior of solid-fluid flow. In this report, we explore a more recent single-phase con...

Solid ± solid and liquid ± solid phase equilibria for the restricted primitive model

A Monte Carlo simulation study is made of the phase diagram of the restricted primitive model and of the solid± liquid and solid± solid phase coexistence curves in particular. At low temperatures, there is liquid± bcc coexistence and with increasing density there is bcc± fcc coexistence. These coexistence curves end in a triple point (liquid± bcc ± fcc) above which only liquid± fcc coexistence ...

CFD Simulation of Gas-Solid Two-Phase Flow in Pneumatic Conveying of Wheat

Computational Fluid Dynamics (CFD) simulations of gas-solid flow through a positive low-pressure pneumatic conveyor were performed using Eulerian-Eulerian framework. Pressure drop in pneumatic conveying pipelines, creation and destruction of plugs along the horizontal and vertical pipes, effect of 90° elbows and U-bends on cross-section concentrations, and rope formation and dispersion were...

Solid Solution Formation during Liquid Phase Sintering

Solid liquid phase changes with different densities

In this paper we present a new thermodynamically consistent phase transition model describing the evolution of a liquid substance, e.g., water, in a rigid container Ω when we freeze the container. Since the density ̺2 of ice with volume fraction β2 , is lower than the density ̺1 of water with volume fraction β1 , experiments for instance the freezing of a glass bottle filled with water show that ...
