The Binary Fluid Ejector- a novel thermal-driven heat pump for low-energy distillation

There are two common technologies that use thermal energy directly to produce cooling – absorption chillers and steam ejectors. Both are old technologies that suffer from serious limitations. MRT is developing a novel Binary Fluid Ejector that can overcome the limitations of prior art to produce a heat pump that can economically harness renewable thermal energy, including waste heat, to do useful work such as air conditioning, process chilling, or distillation/desalination.

Combined Building Integrated PV/Thermal (BIPV/T) collector for net-zero energy building applications

Incorporating the Two-stage Variable Capacity Air Source Heat Pump (TS-VC-ASHP) into Building Integrated Photovoltaic/Thermal (BIPV/T) system has the potential to reduce building heating and cooling costs and dependence on non-renewable heating fuels. ASHPs could boost the quality and quantity of heat output of a BIPV/T system by delivering a seasonal Coefficient of Performance (COP) of between 2.0 and 4.0, which means 2-4 times more energy output than the amount of energy (electricity) consumed.

Development of model for high temperature composite materials used in aerospace

The use of composite materials for high temperature aerospace applications requires new studies in order to better understand the behaviour of these novel materials, and to generate appropriate design tools. The main goals of this project are to develop a set of numerical tools that will be used to predict the fatigue behaviour of advanced high temperature composite materials. The first step will be to complete the development of the tools. Then, the tools will be implemented into existing software currently used by the industry partner.

Experimental investigation of the flow fields within novel compact compressor stages

The aim of the internship is to conduct airflow velocity and turbulence measurements within a novel, compact aircraft engine compressor stage, using a non-intrusive technique, and then compare the results with those obtained from numerical (computational fluid dynamics, CFD) models, thereby developing an understanding as to how the different models deal with turbulence and with the strong curvature of the flow present in such compressor stages.

Flaw growth thresholds in composites

A new generation of composites-intensive aircraft designs promises to dramatically accelerate the growth of a market currently valued at more than $7 billion (USD). The objective of this research program is to propose experimental and modeling methodologies to determine endurance limit for damage onset in composite based on fracture mechanics and fatigue crack initiation monitoring using wave mode propagation based on Modal Acoustic Emission new approaches (MAE).

Strategic safety stock allocation in an assembly supply chain network

The supply chain structure of an engine assembly line consists of several complex flows and processes to satisfy the requirements for on time delivery of these products. The difficulty in managing such systems is due to the fact that more than 1000 parts should be available on time in a synchronized manner to start the assembly procedures and deliver the products on time. Due to the supplier lead time variability, quality inspection related delays and other sources of uncertainty, the adherence to a production plan is almost impossible.

Techniques of aircraft engine vibration analysis

The Master’s student will conduct the investigation of the state-of-the-art of the engine mount-damper-aircraft structure technology to reduce the aircraft structural vibration. He/she will establish the framework for the modeling, based on the test and experiment procedures that are provided by P&WC. The modeling will be planned so that the model results can be verified by the experiment (in future work), and vice versa the changes in the model parameters can be easily implemented into test rig.

Solution of complementarity problems arising from rigid body dynamics simulations

Modeling and simulation of realistic motion is one of the important topics in mechanical engineering and related areas. Such simulations become much more challenging when rigid body dynamics with frictional contacts appears. The total number of contact points is very important and is a key element to determine the difficulty level of the simulation, meaning that if the number of contact points increases, the simulation becomes too difficult or even impossible. In this project, we would like to develop algorithms by which we can do the simulation for large number of contact points.

Machining effects on part integrity and life of aircraft materials

Design, manufacturing and maintenance of aerospace products are cornerstones of the economy and social development of Quebec and Canada. In 2009, more than 78 000 Canadian jobs were related to the aerospace industry from which 45 % are in Quebec. These high technology jobs contribute to the quality of life and the economic growth of our province and our country. To maintain and increase these valued jobs, it is necessary to develop Canadian technologies and know-how in this field.

Research and implementation of haptics device integration with a dynamics simulation engine and applications to milling and drilling force feedback (second stage)

Virtual environments represented by multibody system models play an important role in many applications. Adding the possibility of the user directly interacting with such environments via physical touch using haptics can significantly enhance the usability and range of application of simulated environments.
