    Notes: Abstract A model for predicting the refractive index of sodium iodide (NaI) aqueous solution n NaI as a function of temperature T, NaI concentration c and wavelength λ was determined for moderate parameter variations. The equation accurately predicted the salt concentration required to match n NaI to the refractive index of Pyrex n P.

    Pool boiling of drag-reducing polymer solutions (1983)
    Springer
    Flow, turbulence and combustion 40 (1983), S. 209-222 
    Details
    ISSN: 1573-1987
    Source: Springer Online Journal Archives 1860-2000
    Topics: Mechanical Engineering, Materials Science, Production Engineering, Mining and Metallurgy, Traffic Engineering, Precision Mechanics
    Notes: Abstract The effect of drag-reducing polymeric additives on the critical heat flux and minimum film boiling temperature in subcooled pool boiling of water has been experimentally examined. Three water-soluble polymers, viz. a polyethylene oxide (Aldrich No. 18946-4), a polyacrylamide (Separan AP-30), and a galactomannan polysaccharide (Galactasol-211) have been examined at concentrations of 10, 50, and 100 wppm. The experiment is performed by quenching a hot brass sphere in an isothermal pool of the fluid to be examined and obtaining the corresponding boiling curve. The experiments have been conducted at atmospheric pressure with a pool temperature of 90°C. The results show that the critical heat flux increases by more than 50% while the minimum film boiling temperature increases by more than 110°C when concentrations of 100 wppm of polyox or guar gum are used. For separan solutions, the critical heat flux and minimum film boiling temperature are lower than those for water and go through a minimum at a concentration of ∼10 wppm; the maximum reductions are about 73% and 34°C respectively.

    Surface concentration measurement of a spreading monolayer film using a displacement current technique (1995)
    Springer
    Flow, turbulence and combustion 55 (1995), S. 261-282

    Notes: Abstract There are numerous techniques for measuring surface concentration of monolayer films. While most techniques are suitable only for stationary films, a novel technique is examined for its feasibility in measuring the concentration of a polar monolayer during the spreading of the film. Measurement of the concentration of an octadecanol monolayer while spreading over a water surface is demonstrated with a displacement current measurement technique in conjunction with Wilhelmy plate measurements of the surface pressure. It was found that the displacement current technique can easily measure changes in the film concentration well below those detectable by the Wilhelmy plate. A “gaseous” film region was observed ahead of the leading edge detectable by the Wilhelmy plate. This film region has not been previously reported in the literature. Furthermore, the film front appears to diffuse during the spreading process. Surfactant concentration behavior during spreading is useful for examining and developing models of surface tension driven flows.

    Estimation of the zero shear rate viscosity for dilute solutions of rigid macromolecules with complex configurations (1975)
    New York : Wiley-Blackwell
    Biopolymers 14 (1975), S. 1915-1932 
    Details
    ISSN: 0006-3525
    Keywords: Chemistry ; Polymer and Materials Science
    Source: Wiley InterScience Backfile Collection 1832-2000
    Topics: Chemistry and Pharmacology
    Notes: A method for estimating the zero shear rate viscosity for dilute solutions of rigid macromolecules with complex configurations is proposed; this method is based on the macromolecular kinetic theory of Curtiss, Bird, and Hassager. Macromolecular models constructed from a collection of spheres, cylindrical rods, circular discs, and parallelepipeds with arbitrary dimensions and relative orientations can be easily handled by this method. Comparison with available experimental data for several biopolymers shows excellent agreement. As an application to this method, we investigate the effect of surface roughness on the intrinsic viscosity of spherical particles.

    Prediction of melt elasticity from viscosity data (1974)
    Stamford, Conn. [u.a.] : Wiley-Blackwell
    Polymer Engineering and Science 14 (1974), S. 859-867 
    Details
    ISSN: 0032-3888
    Keywords: Chemistry ; Chemical Engineering

    Notes: A simple method for predicting the primary normal stress function, θ, from viscosity data is proposed. A relation between θ and the viscosity function, θ, based on the Goddard-Miller rheological equation of state, is given. An easy-to-use generalized chart for estimating θ from θ is presented; in order to use this chart, viscosity data must be available from the zero-shear-rate value of the “power law region.” The method was applied to six polymer melts, three polymer solutions, and an aluminum soap solution for which θ had been measured experimentally. Even though θ varied by a factor of 103 over the examined range of shear rate, the theory and experiment seldom differed by more than a factor of 2. The generalized chart for θ was combined with Tanner's theory to prepare a graph which may be used to estimate jet swell from viscosity data. Comparison with experimental data of jet swell for 4 polymer melts shows good agreement.
