Properties of litharge and glycerine mortars

McKinnon, Bain Laughlin (1933-05-10)
Pressure losses and heat transfer for the flow of mixtures of immiscible liquids in circular tubes

Finnigan, Jerome Woodruff (1958-05-14)
Pressure drop and heat transfer for liquid- liquid dispersions in turbulent flow in a circular tube

Wright, Charles Harry (1959-09-09)
Viscosity of liquid - liquid dispersions in laminar and turbulent flow

John Anthony Cengel (1959-09-09)
A study of two-phase liquid-liquid flow in pipes

Soot, Peet Mati (1970-07-06)

The pressure drop for two-phase liquid-liquid flow is theoretically predicted for each flow regime. Empirical correlations, which are applicable in all flow regimes, are also presented for holdup as well as pressure d ...
Momentum and heat transfer characteristics of liquid-liquid dispersions in turbulent flow in an annulus

Dev, Lachhman (1972-01-20)
Periodate oxidation of cellulose - a complete kinetic study

Chandan, Bhaskar Arjundev (1988-10-26)

The effect of over-oxidation on periodate oxidation of cellulose was studied. It was found that the over-oxidation process has a significant effect on the overall reaction. An integrated rate equation was formulated. ...
Calibration and Testing of a Daily Rainfall Erosivity Model

Selker, J. S.; Haith, D. A.; Reynolds, J. E. (American Society of Agricultural Engineers, 1990-09)

A general procedure is presented for calibrating a model for rainfall erosivity based on daily rainfall. The approach is based on probability distributions of wet-day precipitation amount and monthly erosivities which ...
Development and Testing of Single-Parameter Precipitation Distributions

Selker, John S.; Haith, Douglas A. (American Geophysical Union, 1990-11)

Distributed temperature data are used as input and as calibration data for an energy based temperature model of a first order stream in Luxembourg. A DTS (Distributed Temperature Sensing) system with a fiber optic cab ...
Dynamic simulation of drying and quality changes during malt kilning

Coonce, Vincent M. (1991-01-16)

The principal aim of this study was the use and evaluation of dynamic modeling techniques to identify mathematical models for cereal drying rates and quality changes that best describe thin-layer malt drying data. Seve ...
A microcomputer software package for simulation of non-ideal aqueous electrolyte systems at equilibrium

Sinquefield, Scott A. (1991-05-22)

The non-ideal aqueous electrolyte simulator (NAELS) is composed of three major parts: a Newton-Raphson non-linear optimization program written by Weare, et al (1987); an activity coefficient subroutine for non-ideal e ...
Modeling large temperature swings in heat regenerators using orthogonal collocation

Kokron, Carlos J. (1991-06-18)

This thesis examines the transient performance of packed bed heat regenerators when very large temperature differences are involved. The effects of gas temperature on the key gas physical properties of velocity, densi ...
Reactions of glucose in H-Y zeolite catalysts

Lourvanij, Khavinet (1991-06-26)

Y-Zeolite catalysts have the potential to promote the shape-selective conversion of glucose to oxygenated hydrocarbons at fairly low temperature (100 to 130°C). Reaction of glucose solution with H-Y Zeolite catalyst ...
Oxygen mass transfer and shear sensitivity studies during cultivation of Nicotiana tabacum var. Wisconsin 38 in a stirred-tank bioreactor

Henderson, Kelley (1991-12-03)
β-lactoglubin adsorption equilibrium and kinetics at silanized silica surfaces

Krisdhasima, Viwat (1991-12-11)

The adsorption equilibrium and kinetic behavior exhibited by β-lactoglobulin at silanized silicon surfaces of varying hydrophobicity were examined using ellipsometry. Adsorption equilibrium results were used to constr ...
Use of orthogonal collocation in the dynamic simulation of staged separation processes

Matandos, Marcio (1991-12-12)

Two basic approaches to reduce computational requirements for solving distillation problems have been studied: simplifications of the model based on physical approximations and order reduction techniques based on numer ...
Modeling a heat regenerator-reactor with temperature dependent gas properties

Kulkarni, Milind S. (1992-07-22)

This thesis examines the transient response of a packed bed heat regenerator when heated from an initial uniform bed temperature. Very large (1700 K) temperature differences were studied as well as the effect of simul ...
Synthesis of porous, magnetic chitosan beads and application to cadmium ion adsorption

Tzu-Yang, Hsien (1992-07-27)
Fingered Flow in Two Dimensions 2. Predicting Finger Moisture Profile

Selker, J.; Parlange, J.-Y.; Steenhuis, T. (A merican Geophysical Union, 1992-09)

An exact integral solution for the moisture profile in growing fingers in sandy soil is derived from Richards' equation. The solution provides moisture content along a finger as a function of position and time and provid ...
Fingered Flow in Two Dimensions 1. Measurement of Matric Potential

Selker, J.; Leclerq, P.; Parlange, J.-Y.; Steenhuis, T. (American Geophysical Union, 1992-09)

Precise management of the changing matric potential during infiltration into unsaturated soil required the development of miniature, high-speed, planar tensiometers. A novel design was developed, with response time of le ...
