Concentric Contra-Rotating Dual Shaft Vertical Axis Wind Turbine, Emily Walz, Marcellin Zahui, Andrew Shires, Carl Gilkeson

Essential Studies UNDergraduate Showcase

A typical vertical axis wind turbine (VAWT) consists of two or more airfoils all attached to a single central axis. The wind turbine style most commonly found in renewable energy is the horizontal axis wind turbine (HAWT) that have a high energy production efficiency in exchange for requiring large amounts of land and air space. Alternatively, a VAWT can function in low speeds and in smaller less typical locations. As a result, novel VAWT designs are researched to improve their energy efficiency. An example of a novel VAWT is the concentric counter-rotating VAWT investigated theoretically using the 2D computational fluid …

Method To Provide Meta-Stable Operation Of Dc Microgrid Comprising A Pulsed Load, David G. Wilson, Wayne Weaver, Rush D. Robinett Iii, Ronald Matthews, Steven F. Glover

Michigan Tech Patents

A Hamiltonian surface shaping power flow control (HSSPFC) method is used to analyze the meta-stability and adjust pulsed power loads on a DC electric power distribution network. Pulsed power loads are nonlinear, time-variant systems that cause nonlinear limit-cycles. During the on periods of a pulsed load, the system can be in an unstable state and is damped back to stability during the off state of the load. Therefore, over the entire period of the pulse the system may only be assessed as meta-stable. As shown through simulation, HIL and hardware results, the HSSPFC method is more accurate than the other …

Influence Of Stress Triaxiality On Fracture Ductility For Stereo Lithography, Anjali Sandip, Ravi Kiran Yellavajjala

Mechanical Engineering Posters and Presentations

Stress triaxiality is one of the most important factors that controls fracture ductility. The objective of this study was to investigate the influence of stress triaxiality on fracture ductility for specimens’ printed using stereolithography (SL). Dog bone shape specimens were printed using Formlabs® Form 2 Desktop SLA 3D printer. The specimens were built layer by layer with the help of this 3D printer. Each layer of liquid photopolymer is solidified through a computer-controlled ultraviolet (UV) light source with a laser spot size of 140 𝜇m. A photopolymer resin supplied by the manufacturer which comprised of a proprietary mix of Methacrylated …

Low-Carbon Building Skills Website, Faculty Of Applied Science And Technology Sheridan College

Books and Websites

Low-carbon building involves designing, constructing, operating, maintaining, and removing buildings in ways that conserve natural resources and reduce Greenhouse Gas (GHG) emissions. To move towards a low-carbon economy, we need tradespeople who are educated in the design, construction maintenance and operation of buildings, who understand the industrial and constructions sectors, and are trained in low-carbon building skills.

Sheridan College’s participation in the Low Carbon Building Skills (LCBS) project involved developing and delivering low-carbon building skills curriculum across relevant disciplines and involving the full building cycle, from design to operations and optimization. The learning modules address what can be done to …

Comparative Study Of The Microstructure And Mechanical Properties Of Mechanically Alloyed And Spark Plasma Sintered Alxcocrfeni (0≤X≤2)High Entropy Alloys, David Mikhail

Undergraduate Research Posters 2018

High entropy alloys are a new class of material systems that have promising potential in high temperature structural applications. Mechanical alloying (MA) has gained special attention as a powerful non-equilibrium process for fabricating amorphous and nanocrystalline materials, whereas spark plasma sintering (SPS) is a unique technique for processing dense and near net shape bulk alloys with homogenous microstructure. This research paper discusses novel mechanically alloyed followed by spark plasma sintering approach for assessing composition-microstructure-microhardness relationship in AlxCoCrFeNi (0≤x≤2) high entropy alloy as a candidate system. With increasing Al content, there was a gradual change from a fcc-based microstructure to a …

Spark Plasma Sintering Of Soft Magnetic Materials, Harnavdeep Kaur, Taban Larimian, Javier Esquivel

Undergraduate Research Posters 2018

Over the past 3 decades, iron-based soft magnetic alloys such as Finemet (Fe73.5Si13.5B9Nb3Cu1 (at%)) have attracted great interest due to their exceptional magnetic properties like high magnetization, low coercivity, and high curie temperature. However, the production of amorphous precursor requires very high cooling rates, and thus only wires, powders, and thin ribbons are achievable, yet these are not suitable in industrial applications where large volume of bulk magnetic components is required. Mechanical alloying (MA) has gained special attention as a powerful non-equilibrium process for fabricating amorphous and nanocrystalline materials, whereas spark plasma sintering (SPS) is a unique technique for processing …
