Local compositions in thermodynamic excess functions for liquid mixturesAbstract A critical discussion is given of the use of local compositions for representation of excess Gibbs energies of liquid mixtures. A new equation is derived, based on Scott's two‐liquid model and on an assumption of nonrandomness similar to that used by Wilson. For the same activity coefficients at infinite dilution, the Gibbs energy of mixing is calculated wi... ... hiện toàn bộ

Statistical thermodynamics of liquid mixtures: A new expression for the excess Gibbs energy of partly or completely miscible systemsAbstract To obtain a semi‐theoretical equation for the excess Gibbs energy of a liquid mixture, Guggenheim's quasi‐chemical analysis is generalized through introduction of the local area fraction as the primary concentration variable. The resulting universal quasi‐chemical (UNIQUAC) equation uses only two adjustable parameters per binary. Extension to multicomponent... ... hiện toàn bộ

Thermodynamics of mixed‐gas adsorptionAbstract A simple technique is described for calculating the adsorption equilibria for components in a gaseous mixture, using only data for the pure‐component adsorption equilibria at the same temperature and on the same adsorbent. The proposed technique is based on the concept of an ideal adsorbed solution and, using classical surface thermodynamics, an expression ... ... hiện toàn bộ

Group‐contribution estimation of activity coefficients in nonideal liquid mixturesAbstract A group‐contribution method is presented for the prediction of activity coefficients in nonelectrolyte liquid mixtures. The method combines the solution‐of‐functional‐groups concept with a model for activity coefficients based on an extension of the quasi chemical theory of liquid mixtures (UNIQUAC). The resulting UNIFAC model (UNI... hiện toàn bộ

Phân tích thành phần chính phi tuyến sử dụng mạng nơ-ron tự liên kết Dịch bởi AI Tóm tắt Phân tích thành phần chính phi tuyến (NLPCA) là một kỹ thuật mới cho phân tích dữ liệu đa biến, tương tự như phương pháp phân tích thành phần chính (PCA) nổi tiếng. NLPCA, giống như PCA, được sử dụng để xác định và loại bỏ các mối tương quan giữa các biến vấn đề nhằm hỗ trợ giảm chiều, trực quan hóa và phân tích dữ liệu khám phá. Trong khi PCA chỉ xác định c... ... hiện toàn bộ

A model for predicting flow regime transitions in horizontal and near horizontal gas‐liquid flowAbstract Models are presented for determining flow regime transitions in two‐phase gas‐liquid flow. The mechanisms for transition are based on physical concepts and are fully predictive in that no flow regime transitions are used in their development. A generalized flow regime map based on this theory is presented.

Fundamentals of the hydrodynamic mechanism of splitting in dispersion processesAbstract The splitting of globules is an important phenomenon during the final stages of disintegration processes. Three basic types of deformation of globules and six types of flow patterns causing them are distinguished. The forces controlling deformation and breakup comprise two dimensionless groups: a Weber group N ... hiện toàn bộ

Pore and solid diffusion models for fixed‐bed adsorbersAbstract Most models for fixed bed adsorbers have used either the homogeneoussolid or pore diffusion model for the pellets. When the adsorption isotherm is linear, the two models can lead to identical breakthrough curves. The conditions for this equivalence are presented here. It is shown that one of the bulk flow factors that was included in the formulation of one ... ... hiện toàn bộ

Boundary‐layer behavior on continuous solid surfaces: I. Boundary‐layer equations for two‐dimensional and axisymmetric flowAbstract This study deals with boundary‐layer flow on continuous solid surfaces. Flow of this type represents a new class of boundary‐layer problems, with solutions substantially different from those for boundary‐layer flow on surfaces of finite length. In this paper the boundary‐layer behavior on continuous surfaces is examined, and the basic differential and integ... ... hiện toàn bộ
