Direct Numerical Simulation of Liquid Films with Large Interfacial Deformation
Liquid films are important in many industrial applications, but also from a fundamental point of view, they are important two-phase flow systems. In this paper, we develop a sharp interface/level set method for the Direct Numerical Simulation (DNS) of liquid films with large interfacial deformations, and large density ratio between the liquid and the gas phase. We use the ghost fluid method to ...
متن کاملNumerical Analysis of Melting Process of Compounds Containing Nanoparticles for the Development of Phase Change Process
In this work, the melting process of compounds containing nanoparticles of NePCM in a square hole with different angles affected by two pairs of well-spring heat source on horizontal walls was numerically investigated. Four different configurations of elements were employed to investigate the effect of changes in the position of elements on the horizontal walls of the well-spring landscape on t...
متن کاملPlastic Deformation Characteristics of Continuous Confined Strip Shearing Process Considering the Deformation Homogeneity and Damage Accumulation
In the present investigation, two dimensional elastoplastic finite element analysis was conducted to assess the deformation characteristics of Al 1100 alloy during continuous confined strip shearing (C2S2) process. The results of simulations showed that the plastic strain distribution across the deformed sample is non-uniform irrespective of the amount of friction and C2S2 die angle. The most u...
متن کاملFinite element simulation of pyroplastic deformation, anisotropic shrinkage and heterogeneous densification for ceramic materials during liquid phase sintering process
Pyroplastic deformation is a distortion of the ceramic shape during the sintering process. It occurs because the flow of the vitreous phase at high temperature and the applied stress due to the weight of the product during sintering process. The aim of this paper deals with describing a numerical-experimental method to evaluate the pyroplastic deformation, to predict the anisotropic shrinkage a...
متن کاملSolid-Solid Phase Transformation Kinetics
Natural formation of the bcc modification for Co was demonstrated to occur upon precipitation of Co in supersaturated Au90Co10 alloy. The microstructural evolution was investigated by high resolution transmission electron microscopy. Co precipitation starts with the formation of very thin coherent plates along {100}Au. This initially precipitated Co was shown to be a hitherto unknown metastable...
