Dynamic Stall on Pitching Cambered Airfoil with Phase Offset Trailing Edge Flap
(American Institute of Aeronautics and Astronautics (AIAA), 2020-04-20)Dynamic stall on wind turbine blades often leads to severe fatigue that tends to decrease the lifespan of the blades. To mitigate cyclic loading on the blades, trailing edge flaps (TEF) may be used to control the energy ... -
Dynamic Weight Estimation of Non-Singulated Objects
(University of Waterloo, 2018-08-21)Weight estimation is a common practice throughout many industries, though it typically requires that the objects to be weighed remain motionless. More often than not, it is beneficial to allow objects to move freely through ... -
Dynamics of a Three_Wheel Vehicle with Tadpole Design
(University of Waterloo, 2015-01-15)This study investigates the effect of applying camber angle on the handling, lateral stability, and ride comfort of a three-wheeled vehicle, which has two wheels in the front and one in the back, known as a tadpole design. ... -
Dynamics of Gyroelastic Continua
(University of Waterloo, 2014-03-07)This work is concerned with the theoretical development of dynamic equations for gyroelastic systems which are dynamic systems with four basic types of continuous mechanical influences, i.e. inertia, elasticity, damping, ... -
Economic, Environmental, and Health Impact Analysis of Developing Hydrogen Economy in Canada
(University of Waterloo, 2022-01-21)The greatest challenge to the development of a cleaner energy system is economic issues. However, if the environmental and health externalities of the current energy system is considered, other energy alternatives become ... -
Eddy Current Probes Design for Defect Detection in Metallic Parts Made by Additive Manufacturing Processes
(University of Waterloo, 2023-01-04)Non-destructive testing (NDT) is the method where an object or materials are being tested for any type of damage or features without harming the object during the process. There are different NDT techniques; in this ... -
Effect of alloy composition on hot deformation behavior of some Al-Mg-Si alloys
(Elsevier, 2018-03-01)The hot flow stress behavior of three Al-Mg-Si alloys was determined by performing hot deformation compression tests on a Gleeble 3500 thermomechanical simulator over the temperature range 400 °C–550 °C and at strain rates ... -
