Blend times and power consumption have been measured for Newtonian and pseudo- plastic fluids in agitated, baffled vessels with diameters of 0.30,0.61 and 1.83 m. The viscosities of the fluids were selected to give a ...

This thesis is concerned with the development of a prototype electromagnetic flowmeter for dielectric liquids. A initial prototype flowmeter is tested in laboratory conditions with a liquid of low conductivity, the ...

The response of an Electromagnetic Flowmeter to a secondary, nonconducting phase in a continuous conducting phase is investigated. Experiments are carried out on a commercial 2" Foxboro flowmeter with sinusoidal mains ...

Mechanical seals are used extensively on rotary applications where the sealed fluid is under pressure. They may rightly be considered to be generally reliable and trouble free, many giving lives of over 3 years. However, ...

The dispersion of air into water was studied in a tall agitated vessel (ungassed liquid depth = 2.4 x vessel diameter) fitted with four different triple impeller combinations: 1. Three identical Rushton turbines 2. One ...

This thesis is focused on the improvement of the meter performance and power consumption of non-mechanical flowmeters such as the conventional electromagnetic flowmeter and the fluidic oscillator. Each flowmeter is studied ...

The design and testing of an ultrasonic time of ight Mach number probe for use in the bypass duct of an aircraft gas turbine is presented. Analysis of the time and frequency domain behaviour of the type of thickness ...

The operational performance criteria of fluidic oscillators are described in relation to the requirements of a domestic water meter. The problems associated with developing a novel water meter using fluidic oscillatory ...

The accurate measurement of multiphase flows of oil/water/gas is a critical element of oil exploration and production. Thus, over the last three decades; the development and deployment of in-line multiphase flow metering ...
