This book was released on 1966 with total page 29 pages. Available in PDF, EPUB and Kindle. Book excerpt: Equipment designed to study the effect of polymer additives on fluid flow is described. The objective of the equipment is the following: (1) Visual observation of the boundary layer using stereoscopic techniques. (2) Measurement, by means of a hydrophone, of the change in pressure fluctuations due to the additives. (3) Determination of the accuracy of pitot tube measurements in visoelastic fluids and (4) Determination of the material constants used in the constitutive equation studied. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: Everything flows, so rheology is a universal science. Even if we set aside claims of such width, there can be no doubt of its importance in polymers. It joins with chemistry in the polymerisation step but polymer engineering is supreme in all the succeeding steps. This is the area concerned with the fabrication of the polymer into articles or components, with their design to meet the needs in service, and with the long and short term performance of the article or component. This is a typical area of professional engineering activity, but one as yet without its proper complement of professional engineers. An understanding of polymer rheology is the key to effective design and material plus process selection, to efficient fabrication, and to satisfactory service, yet few engineers make adequate use of what is known and understood in polymer rheology. Its importance in the flow processes of fabrication is obvious. Less obvious, but equally important, are the rheological phenomena which determine the in-service performance. There is a gap between the polymer rheologist and the polymer engineer which is damaging to both parties and which contributes to a less than satisfactory use of polymers in our society. It is important that this gap be filled and this book makes an attempt to do so. It presents an outline of what is known in a concise and logical fashion. It does this starting from first principles and with the minimum use of complex mathematics.

Available in PDF, EPUB and Kindle. Book excerpt: "In the course of an investigation of the turbulent flow properties of dilute high polymer solutions in organic solvents, a number of supplementary investigations were required. These were: 1. Determination of the molecular weights of a number of polymers by intrinsic viscosity measurements. 2. Determination of the effect of pumping on the degradation of high polymers in dilute solutions. This included development of a method for estimating the concentration of dilute polymer solutions. 3. Determination of the effects of density, viscosity and non-Newtonian behavior on the calibration of turbine flow meters"--Introduction, leaf 1.

Available in PDF, EPUB and Kindle. Book excerpt: Flow of aqueous solutions of Polyox WSR-301, with concentrations of 1.0 to 200 wppm, past circular cylinders was investigated in the drag-transition region of Reynolds numbers. Drag force, pressure distribution, and separation angle were measured on cylinders with diameters from 1/4 to 1-1/2 inch. Lift and drag forces acting on a NACA-0024 hydrofoil-model were also measured. The polymer additive was found to alter only those force coefficients which have a Reynolds-number transition region. Two distinct types of cylinder drag transition were observed: (1) At high concentrations, transition from sub-critical to a transcritical flow occurred at the same free-stream velocity independent of body diameter; and (2) at low concentrations and/or molecular weights, tripping from a sub-critical to a super-critical flow occurred at a well defined flow condition which was a function of free-stream velocity, body diameter, and turbulent pipe-flow friction reduction. In all cases, transition occurred earlier than that in the pure solvent. The polymer had a de-stabilizing effect on the boundary-layer flow.

Available in PDF, EPUB and Kindle. Book excerpt: Five studies are presented in this publication: A comparison between the behaviour of polymer solutions and flow characteristics of linear elastico-viscous fluid models. The study shows that no linear model can predict consistently all the observed non-Newtonian phenomena of polymer solutions; Turbulent flow of dilute polymer solutions through an annulus. Experimental and theoretical results are presented; Measurements of the dynamic response of flowing polymer solutions with a vibrating torsional quartz crystal are presented. The dynamic elastico-viscous response is found to be independent of the flow characteristics and shear rates; Drag reduction in developing boundary layers by injection of polymer solutions. Reduction of local friction coefficients is of the order of 65 percent, however, energy losses in the injection region decrease the total drag reduction efficiency. Effect of the injection concentration and discharge, width of slot and mean stream velocity are found; Drag reduction and degradation tests of several polymer solutions are presented. (Author).
