Investigating the heat-treatment process for 316L alloy powders with the application in binder jetting metal additive manufacturing
(University of Waterloo, 2020-07-23)Metal binder jetting (BJ) is a manufacturing process which involves the deposition of metal powder and an adhesive liquid binder layer-by-layer to fabricate metal parts. BJ as-printed parts are in essence loose particles ... -
Investigating the Impact of External Passive Compression on Central and Peripheral Hemodynamics
(University of Waterloo, 2014-12-22)The use of passive compression has been extended from a clinical treatment to an elective tool used by healthy individuals in an attempt to improve exercise performance. The rationale being that graduated compression socks ... -
An Investigation into Radiative Property Variations across Pre-Annealed Advanced High Strength Steel Coils
(University of Waterloo, 2023-05-29)In recent years, increasingly stringent crashworthiness and emissions regulations have driven automakers to consider novel materials for automotive lightweighting. Advanced high-strength steels (AHSS) used in automotive ... -
Investigation into the Effect of Thermal Management on the Capacity Fade of Lithium-ion Batteries
(University of Waterloo, 2017-01-03)The popularity of electric (and hybrid) vehicles has raised the importance of effective thermal management for lithium-ion batteries, both to prevent thermal runaway leading to a fire hazard, and to minimize capacity fade ... -
Investigation of a Jacobian-free Newton-Krylov solution to multiphase flows
(University of Waterloo, 2014-07-22)The current study is focused on investigating a Jacobian-Free Newton-Krylov (JFNK) method to obtain a fully-implicit solution for two phase flows. In the JFNK formulation, the Jacobian matrix is not directly determined ... -
Investigation of an Inhomogeneous Mixing Model for Conditional Moment Closure Applied to Autoignition
(University of Waterloo, 2010-04-28)Autoignition of high pressure methane jets at engine relveant conditions within a shock tube is investigated using Conditional Moment Closure (CMC). The impact of two commonly used approximations applied in previous work ... -
Investigation of Blast Load Characteristics On Lung Injury
(University of Waterloo, 2010-03-31)In many parts of the world, civilians and peacekeepers are exposed to potentially serious injury from blasts and explosions. Providing insight into the trauma thresholds for blast injury is necessary for the development ... -
Investigation of Blast–related Fluid Cavitation using a Novel Polymeric Hopkinson Bar–Confinement Chamber Apparatus
(University of Waterloo, 2017-08-24)Mild Traumatic Brain Injury (mTBI) associated with blast exposure has become an increasing issue in military conflicts, with the most common exposure being improvised explosive devices. Exposure to blast accounted for ... -
