First-Order Phase Transformation at Constant Volume: A Continuous Transition? [PDF]

open access: yesEntropy, 2021
We describe a first-order phase transition of a simple system in a process where the volume is kept constant. We show that, unlike what happens when the pressure is constant, (i) the transformation extends over a finite temperature (and pressure) range, (

A Comparison Between Ripening Under a Constant Volume and Ripening Under a Constant Surface Area [PDF]

open access: yesNanomaterials
The classic Lifshitz–Slyozov–Wagner (LSW) theory of ripening assumes a constant volume. In comparison, we present here a model of ripening assuming a constant surface area, which has occurred in the microstructure changes in intermetallic compounds in ...

Comparative FE-studies of interface behavior of granular Cosserat materials under constant pressure and constant volume conditions

open access: yesArchives of Mechanics, 2021
This article shows the outcomes of a systematic series of finite element (FE) calculations relevant to the shear behavior of a particulate-continuum interface system under different normal boundary conditions. In this respect, shearing of a thin and long

EFFECT OF CONSTANT VOLUME STRUCTURE PARAMETERS ON GRAIN VENTILATION DRYING [PDF]

open access: yesEngenharia Agrícola, 2023
The structural parameters of a grain dryer are directly related to the its energy consumption and quality formation. Therefore, based on the Ergun model, air state parameters and uniformity evaluation method, the effect of changes in the ventilation area

Buckling of Tapered Columns with Polygon Cross-Section [PDF]

open access: yesComputational Engineering and Physical Modeling, 2018
This paper is concerned with the elastic stability of slender tapered columns of regular polygon cross-section with constant volume is presented. Various end conditions of the tapered columns such as pinned ends, clamped -pinned ends and clamped ends are

Swirling-sweepers [PDF]

open access: yesACM SIGGRAPH 2004 Sketches on - SIGGRAPH '04, 2004
Summary: Swirling-sweepers is a new method for modeling shapes while preserving volume. The artist describes a deformation by dragging a point along a path. The method is independent of the geometric representation of the shape. It preserves volume and avoids self-intersections, both local and global.

Buckling of Tapered Heavy Columns with Constant Volume

open access: yesMathematics, 2021
This paper studies the buckling of standing columns under self-weight and tip load. An emphasis is placed on linearly tapered columns with regular polygons cross-section whose volume is constant. Five end conditions for columns are considered.

On the algorithm to perform Monte Carlo simulations in cells with constant volume and variable shape

open access: yesCondensed Matter Physics, 2022
In simulations of crystals, unlike liquids or gases, it may happen that the properties of the studied system depend not only on the volume of the simulation cell but also on its shape.

Free Vibrations of Tapered Horseshoe Circular Arch with Constant Volume

open access: yesApplied Sciences, 2020
This paper presents free vibrations of the tapered horseshoe circular arch with a constant volume. The volume of the arch is constant, and the cross-sectional shape of the arch is square and circular.

An internal swelling factor model to examine the influence of permeability anisotropy on coalbed methane extraction

open access: yesEnergy Science & Engineering, 2020
Owing to the characteristics of coal reservoirs, the gas flow capacity and permeability exhibit strong anisotropy. The anisotropy in terms of the magnitude, which corresponds to the permeability in the horizontal direction being several orders of ...
