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 ... -
Fundamental Characteristics of Turbulent Opposed Impinging Jets
(University of Waterloo, 2000)A fundamental study of two turbulent directly opposed impinging jets in a stagnant ambient fluid, unconfined or uninfluenced by walls is presented. By experimental investigation and numerical modeling, the main characteristics ... -
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 ... -
Cell Permeabilization Using Supercritical Carbon Dioxide
(University of Waterloo, 2001)Supercritical fluids have unique properties which may make them ideal as reaction media for biotransformation or extractive solvents. Supercritical fluids are ideal for reducing diffusivity limitations over conventional ... -
The Numerical Prediction of the Dent Resistance of Aluminum Structural Panel Assemblies
(University of Waterloo, 2001)An examination of static and dynamic dent resistance of structural panel assemblies representing automotive hoods is described in this thesis. Fabricated panel assemblies incorporating typical components of real automotive ... -
Numerical Prediction of Panel Dent Resistance Incorporating Panel Forming Strains

Spectral Analysis of Wave Propagation Through a Polymeric Hopkinson Bar
(University of Waterloo, 2001)The importance of understanding non-metallic material behaviour at high strain rates is becoming ever more important as new materials are being developed and used in shock loading applications. Applying conventional ... -
A Simplified Analysis of Radiant Heat Loss Through Projecting Fenestration Products
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2001)Current window analysis algorithms can deal with many features, including low-e coatings and substitute fill gases. These methods were developed for products with planar glazings. Results can be generated for projecting ... -
Evaluation of FFT Based Cross-Correlation Algorithms for Particle Image Velocimetry
(University of Waterloo, 2002)In the current study, the four most common Particle Image Velocimetry (PIV) cross-correlation algorithms were evaluated by measuring the displacement of particles in computer generated images. The synthetic images were ... -
The Application of Particle Image Velocimetry in a Small Scale Wind Tunnel
(University of Waterloo, 2002)This study investigated the applicability of Particle Image Velocimetry (PIV) as a velocity measurement technique for use in wind tunnel flows. To carry out the investigation, a small scale wind tunnel was designed and ... -
Corrosion of reinforcing steel in loaded cracked concretes exposed to de-icing salts
(University of Waterloo, 2003)The corrosion of the reinforcing steel in concrete by de-icing salts is one of the major issues concerning the durability of reinforced concrete. Different methods have been used to protect the reinforcing steel, but ... -
A Comparison of Calculated and Measured Indoor-Side Window Temperature Profiles
(American Society of Heating, Refrigerating and Air-Conditioning Engineers, 2003)Computer-generated surface temperature profiles are presented for the indoor side, vertical centerline of two windows and a calibration transfer standard (CTS). These specific configurations were chosen because they match ... -
Modeling of Fluid Flow and Heat Transfer for Optimization of Pin-Fin Heat Sinks
(University of Waterloo, 2004)In this study, an entropy generation minimization procedure is employed to optimize the overall performance (thermal and hydrodynamic) of isolated fin geometries and pin-fin heat sinks. This allows the combined effects ... -
Modeling of Thermal Joint Resistance for Sphere-Flat Contacts in a Vacuum
(University of Waterloo, 2004)As a result of manufacturing processes, real surfaces have roughness and surface curvature. The real contact occurs only over microscopic contacts, which are typically only a few percent of the apparent contact area. ... -
