Non-Newtonian fluid flow measurement using sharp crested notches

Khahledi, Morakane Charlotte January 2014 (has links)
Master of Technology: Civil Engineering In the Faculty of Engineering At the Cape Peninsula University of Technology 2014 / Notches, particularly rectangular and V shaped are the cheapest and most common devices used to measure the flow rate of water in open channels. However, they have not been used to measure the flow rate of non-Newtonian fluids. These viscous fluids behave differently from water. It is difficult to predict the flow rate of such fluids during transportation in open channels due to their complex viscous properties. The aim of this work was to explore the possibility of extending the application of especially rectangular and V-shaped notches to non-Newtonian fluids. The tests reported in this document were carried out in the Flow Process and Rheology Centre laboratory. Notches fitted to the entrance of a 10 m flume and an in-line tube viscometer were calibrated using water. The in-line tube viscometer with 13 and 28 mm diameter tubes was used to determine the fluid rheology. Flow depth was determined using digital depth gauges and flow rate measurements using magnetic flow meters. Three different non-Newtonian fluids, namely, aqueous solutions of Carboxymethyl Cellulose (CMC) and water-based suspensions of kaolin and bentonite were used as model non-Newtonian test fluids. From these the coefficient of discharge (Cd) values and appropriate non-Newtonian Reynolds numbers for each fluid and concentration were calculated. The experimental values of the coefficient of discharge (Cd) were plotted against three different definitions of the Reynolds number. Under laminar flow conditions, the discharge coefficient exhibited a typical dependence on the Reynolds number with slopes of ~0.43-0.44 for rectangular and V notches respectively. The discharge coefficient was nearly constant in the turbulent flow regime. Single composite power-law functions were used to correlate the Cd-Re relationship for each of the two notch shapes used. Using these correlations, the Cd values could be predicted to within ±5% for the rectangular and V notches. This is the first time that such a prediction has been done for a range of non-Newtonian fluids through sharp crested notches. The research will benefit the mining and food processing industries where high concentrations of non-Newtonian fluids are transported to either disposal sites or during processing.

AN IMPLEMENTATION OF DYNAMIC DATA ACQUISITION MEASUREMENTS

Pesciotta, Eric, Portnoy, Michael 10 1900 (has links)
ITC/USA 2006 Conference Proceedings / The Forty-Second Annual International Telemetering Conference and Technical Exhibition / October 23-26, 2006 / Town and Country Resort & Convention Center, San Diego, California / As data acquisition systems evolve and begin utilizing new avenues of acquisition such as Ethernet, an entirely new range of flight test capabilities become available. These new capabilities, defined by acquisition, monitoring, and varying of test measurements, enhance previous operation as they can now be realized during flight. Achieving such high levels of integration between ground station and test vehicle involves complex network protocols. Implementing such systems from scratch would be a time consuming and costly proposition. Fortunately, employing Internet protocols (TCP/IP) over Ethernet provides a cornucopia of readily available technology. Using state-of-the-art integration techniques, modern data acquisition systems can leverage years of proven technology offered by the Internet Engineering Task Force (IETF) and the World Wide Web Consortium (W3C). This paper discusses an implementation of dynamic data acquisition measurements for use in network data acquisition systems. The methodology used to determine whether or not a measurement can and should be variable during a flight test is examined in detail along with a discussion of the advantages of dynamically varying flight test measurements. Finally, an implementation is presented which successfully integrates Internet protocols with modern flight test equipment using the techniques described above for dynamic data acquisition measurements.
