Breakup of a surface-mounted droplet by an impinging jet flow
(University of Waterloo, 2023-09-18)Droplet removal under wind-forcing arises in many engineering applications, such as surface cleaning. In these applications, the efficiency of the system can be affected by droplet breakup, since smaller droplets are harder ... -
Breakup Process of Plane Liquid Sheets and Prediction of Initial Droplet Size and Velocity Distributions in Sprays
(University of Waterloo, 2001)Spray models are increasingly becoming the principal tools in the design and development of gas turbine combustors. Spray modeling requires a knowledge of the liquid atomization process, and the sizes and velocities of ... -
Bright and efficient blue polymer light emitting diodes with reduced operating voltages processed entirely at low-temperature
(Royal Society of Chemistry, 2015-09-03)Hybrid blue polymer light emitting diodes (PLEDs) with high efficiencies, luminance >20 000 cd m−2 and low operating voltages are obtained using processing temperatures ≤150 °C. By briefly applying an electric field across ... -
Burning Behaviour of Heavy Gas Oil from the Canadian Oil Sands
(University of Waterloo, 2014-09-17)This work presents the first systematic investigation and characterisation of the burning behaviour of untreated heavy gas oil from the Canadian oil sands, an intermediate product in the upgrading process of forming synthetic ... -
Calculating Center-Glass Performance Indices of Glazing Systems with Shading Devices
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2008)Building energy consumption and loads are strongly influ-enced by solar gain and heat transfer through the centre-glass area of windows. Methods have been devised to calculate the corresponding energy performance indices ... -
Calculating Center-Glass Performance Indices of Windows
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1998)Building envelope performance is strongly influenced by solar gain and heat transfer through windows. The majority of this energy gain or loss passes through the center-glass area of the glazing system. Various methods ... -
Calculating Center-Glass Performance Indices of Windows with a Diathermanous Layer
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2006)The fenestration chapter of the 2005 ASHRAE Hand-book—Fundamentals (ASHRAE 2005) has long included methods for determining the U-factor and solar heat gain coef-ficient (SHGC), or window performance indices, using the ... -
Calculating the Solar Heat Gain of Window Frames
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1999)It is not practical to measure the solar heat gain of a window frame. It is more practical to do so by calculation. Typically, the frame solar heat gain is a small component of the total or is small in absolute terms so ... -
Calculating Window Solar Heat Gain
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 1995-07)Window design has been revolutionized-largely by the introduction of low emissivity (low-e) coatings and substitute fill gases. The large number of design options necessitates the use of computer simulation for development ... -
Calibration and 3D Model Generation for a Low-Cost Structured Light Foot Scanner
(University of Waterloo, 2013-01-25)The need for custom footwear among the consumers is growing every day. Serious research is being undertaken with regards to the fit and comfort of the footwear. The integration of scanning systems in the footwear and ... -
Can physical joint simulators be used to anticipate clinical wear problems of new joint replacement implants prior to market release?
(Sage Publications, 2016-05-09)One of the most important mandates of physical joint simulators is to provide test results that allow the implant manufacturer to anticipate and perhaps avoid clinical wear problems with their new products. This is best ... -
Capacitive Micromachined Ultrasound Transducers for Non-Destructive Testing Applications
(University of Waterloo, 2020-05-26)The need for using ultrasound non-destructive testing (NDT) to characterize, test and detect flaws within metals, led us to utilize Capacitive Micromachined Ultrasound Transducers (CMUTs) in the ultrasound NDT field. This ... -
Capillary-discharge ignition of dispersed-phase Al@CuO core-shell thermite particles in a liquid filled microchannel
(University of Waterloo, 2022-11-09)Aluminum based thermites are a broad class of highly tunable solid energetic materials that can be formulated to perform as pyrotechnics, propellants, or explosives. Their functional versatility, energy density, reactivity ... -
