Local compositions in thermodynamic excess functions for liquid mixtures
Tập 14 Số 1 - Trang 135-144 - 1968
AbstractA 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 with the new equation as well
as th...
Statistical thermodynamics of liquid mixtures: A new expression for the excess Gibbs energy of partly or completely miscible systems
Tập 21 Số 1 - Trang 116-128 - 1975
AbstractTo 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 systems requires
no ternary (or ...
Thermodynamics of mixed‐gas adsorption
Tập 11 Số 1 - Trang 121-127 - 1965
AbstractA 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 analogous to
Raoult's law is obta...
Group‐contribution estimation of activity coefficients in nonideal liquid mixtures
Tập 21 Số 6 - Trang 1086-1099 - 1975
AbstractA 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 (UNIQUAC Functional‐group Activity Coefficients)
contains two a...
Phân tích thành phần chính phi tuyến sử dụng mạng nơ-ron tự liên kết Dịch bởi AI
Tập 37 Số 2 - Trang 233-243 - 1991
Tóm tắtPhân 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 các mối tương quan tuyến tính
giữa...

A model for predicting flow regime transitions in horizontal and near horizontal gas‐liquid flow
Tập 22 Số 1 - Trang 47-55 - 1976
AbstractModels 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 processes
Tập 1 Số 3 - Trang 289-295 - 1955
AbstractThe 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 NWe and a viscosity group NVi. Breakup occurs when NWe exceeds a critical
value (NW...
Pore and solid diffusion models for fixed‐bed adsorbers
Tập 20 Số 2 - Trang 228-238 - 1974
AbstractMost 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 pore diffusion
model will be sign...
Boundary‐layer behavior on continuous solid surfaces: I. Boundary‐layer equations for two‐dimensional and axisymmetric flow
Tập 7 Số 1 - Trang 26-28 - 1961
AbstractThis 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 integral momentum equations
of boundar...
