Helicopter Wake Modeling and its Interaction with Pesticide Droplet Transport

Aerial spraying (from an aircraft or helicopter) is a crucial component in the management of forest and agricultural lands around the world. Regulatory agencies, government laboratories, and industry have a considerable interest in optimizing the effectiveness of aerial spraying. To deliver aerial spray products with accuracy to their intended target on the ground requires understanding numerous influences primary among them meteorological effects, complex air flows in the wake of the spray aircraft and gravitational effects.

CFD Analysis of the Microsys Cold Gas Inflation System

Microsys is a Mississauga company that designs and sells specialized test equipment to airbag manufacturers worldwide. The Cold Gas Inflation System (CGS) allows these manufacturers to test the inflation characteristics of airbag systems in a simple, safe, and inexpensive manner. The CGS involves the rapid discharge of a compressed gas, which the company would like to better understand, in order to further develop this system.

Colorimetric test strips for oil/fuel/ethanol mixtures

There is a need for customers to use a simple test method to determine if the fuel blends they are using are of the proper composition for fuel efficiency, environment- friendliness and engine cylinder compatibility. But it is difficult to determine the composition of oil/fuel/ethanol mixtures without detailed and expensive chemical analysis. It is because the different hydrocarbons in oils or in fuels are hard to differentiate by physical change or by simple chemical reactions such as pH change.

Impact modeling of composite aircraft structure

Composite structures are vulnerable to impact damage, and have to satisfy certification procedures for high velocity impact from bird strike and foreign object damage. Since performing full scale impact tests is highly expensive and thus impractical, the development of validated analytical tools for the prediction of the structural response is essential for the industry to reduce development costs and to speed up the development process.

Risk-based Winterization of Assets Operating in Harsh Environments

The proposed project is an extension of an ongoing project with American Bureau of Shipping (ABS), which aims to develop a performance-based winterization guideline for assets operating in harsh environments. The project has led to a novel approach of assessing need of winterization and evaluating extent of winterization required to maintain assets in safe operating condition. The main objective of the proposed project is to further validate the developed approach through a real-world case, i.e., winterization of a ferry operating in offshore Newfoundland and Labrador.

Optimization of key-to-key collision repair process system

The intent of this project is to reduce the cycle time in the vehicle repair process across the Carstar network. The project also includes developing process models that will help in guiding Carstar to reduce cycle time in major process steps for all stores of varying size and disparate locations. During the process of investigation and analyzing the data, the waste (inventory limitations, conflicts, redundant process steps and blockage) will be identified and eliminated.

Advanced Bio-composites for automotive sector

The proposed project seeks to develop biocomposite technology and products for the auto manufacturing industries. Eight graduate students under the supervision of Dr. Mohini Sain, will work on manufacturing processes, mechanical characterization and development of molds for various types of bio-composites which have direct application in auto-industries and can act as substitute for fossil fuel based composites. The two partner organizations will be the Centre for Biocomposites and Biomaterials Processing (CBBP), Faculty of Forestry, Univ.

Truck safety survey

Fleetmetrica is a new business startup that offers an innovative and patent-pending technology called SafetyMonitor for monitoring and controlling fleet safety of large commercial vehicles.  Fleetmetrica has achieved success with initial fleets, including improved driver habits using their product and are interested in formally quantifying the effectiveness of their technology. 

Compressor load optimization

One of the main issues for automakers in today’s green economy is ensuring their vehicles have the highest fuel economy possible in order to deal with constantly increasing fuel costs. The improved fuel efficiency of vehicles provides money savings for customers, reduced carbon dioxide emissions, less dependency on oil, and lastly increased energy sustainability. The compressor load optimization project aims at improving the efficiency of the refrigerant cycle inside of a vehicle leading to improved fuel economy, reduced emissions, and lastly an extended comfort time in stop/start vehicle.

Sensorless control of brushless DC motors at low speeds

Accelerated Systems is a leader in the design and implementation of control systems for electric vehicles; especially vehicles driven by permanent-magnet brushless DC (BLDC) motors.  One of the key technological challenges in the use of BLDC motors is that traditional control, especially at low speeds, requires external sensors to determine the rotor position.  These external sensors then become an added cost and maintenance challenge.  In this project, we will investigate novel control strategies that infer the rotor position from measurements of motor voltages and currents only.  A succes
