This book was released on 1993 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The overall objective of this project is to perform experiments to understand the effect of high shear and extensional properties on the atomization of coal-water slurries (CWS). In the atomization studies, the mean drop size of the CWS sprays will be determined at various air-to CWS. A correlation between the extensional and high shear properties, particle size distributions and the atomization will be made in order to determine the influence of these parameters on the atomization of CWS. During this past quarter, an attempt was made to establish a theoretical relationship between the sauter mean diameter, (SMD), theAir/Fuel ratio and the viscosity. Also the effect of polymeric additives on the rheology of glycerol was studied.

Book excerpt: The overall objective of this project is to perform experiments to understand the effect of high shear and extensional properties on the atomization of coal-water slurries (CWS). Several CWS were prepared and their low shear rheological properties (i.e. rheology as a function of concentration, constant shear and, additive type, stability and slip effect) performed. The stability was determined using a settling column to study the shift in mass of the CWS as a function of time. Low shear testing of the slurries were used to determine the effect of yield stress on the concentration of the slurries.

The established relationship was modified to account for the high shear viscosity data.

This book was released on 1992 with total page 14 pages. Available in PDF, EPUB and Kindle. Book excerpt: During the previous quarter, it was noted that understanding the rheology of polymeric additives used in enhancing the stability of the CWS was essential in meeting the project objectives. Thus, further review of the literature was carried out to gain information on the rheology of polymeric additives, particularly at high shear rates. Philippoff and Hess [1] reported the existence of four distinct flow regions in the behavior of flow curve analysis of polymer solutions (Figure 1). These regions are characterized by (1) A Newtonian Region; (2) A non-Newtonian pseudoplastic region; (3) A second Newtonian region at high shear rates 105 to 106 sec−1; (4) and a region of steepening slope identified as the onset of turbulence. Efforts during this past quarter were therefore directed towards the study of high shear rheology of the CWS.

This book was released on 1995 with total page 143 pages. Available in PDF, EPUB and Kindle. Book excerpt: The objective of this study was to understand the effect of low shear, high shear rheology, viscoelastic, and extensional properties on the atomization of CWS. In the atomization studies, the mean drop size of the CWS sprays were determined at various air-to-CWS ratios using a Malvern 2600 particle size analyzer and a Delavan Solid Cone Atomizing Nozzle. Solids-loading, coal particle size distributions, and chemical additives were varied in order to determine the significant properties that influence CWS atomization. A correlation of the mass mean droplet size with high shear, viscoelastic and extensional behaviors were made in order to determine the influence of these parameters on CWS atomization.

A CV20 attachment to a Haake RV20 viscometer and a PQ45 sensor were received during this past quarter. This was followed by several hours of calibration of the sensors using a non-elastic fluid. Also, a literature review was made in order to further understand dynamic oscillatory shear flow.

This book was released on 1995 with total page 8 pages. Available in PDF, EPUB and Kindle. Book excerpt: The analysis of pipeline transportation of highly concentrated suspensions such as coal-water slurries, can exhibit several flow characteristics depending on the concentration and the physical parameters of the dispersed phase. Experiments were conducted for coal-water slurries flows in a series of horizontal capillary tubes of diameters 0.8, 1.5 and 3.0 mm and 100 mm in length, in order to investigate the effect of concentration, pressure drop, and the transitional Reynolds number from laminar to turbulent flow in a homogeneous slurry. The solid concentration was varied from 15% to 63% in 0.1% xanthum gum solution. Pressure drop and the volume flow measurement were made using HVA-6 Capillary viscometer. The Reynolds numbers obtained were found to be dependent on the slurry concentration and the viscosity of the slurry mixture, but independent of the capillary diameter.
