Mechanical and Aerospace Engineering

The Department

In addition to University and Graduate Faculty regulations, all Engineering departments share common procedures that are described in Section 18 of the General Regulations (see p.66).

The Department of Mechanical and Aerospace Engineering offers programs of study and research leading to M.Eng. degrees in Aerospace Engineering, Materials Engineering, and Mechanical Engineering, and to Ph.D. degrees in Aerospace and Mechanical Engineering. These degrees are offered through the Ottawa-Carleton Institute for Mechanical and Aerospace Engineering, which is jointly administered by the Department of Mechanical and Aerospace Engineering at Carleton University, and the Department of Mechanical Engineering at the University of Ottawa. For further information, including admission and program requirements, see p.241.

Programs of research and study are offered in several areas:

* Aerodynamics and Gas Dynamics
* Heat Transfer
* Stress and Failure Analysis
* Lightweight Structures and Aeroelasticity
* Vibration Analysis
* Computer-Aided Design and Engineering
* Robotics
* Control Systems
* Vehicle (Performance and Safety)
* Engineering
* Nuclear Engineering
* Energy Systems
* Energy Conversion and Utilization
* Manufacturing Engineering
* Materials Engineering

The Department has a major research commitment, both analytical and experimental, to thermofluid-dynamic and mechanical problems of gas turbine engine design and operation. Current work includes flow prediction and analysis in turbo-machines; two-and three-dimensional boundary layer behaviour; tip-leakage effects and other losses; dynamics of gas turbine power plants; design and performance of highly loaded turbines; engine noise; stress, deformation, and vibration of compressor and turbine blades and discs; finite element analysis; dynamics of high-speed rotors and failure modes of materials in extreme environments.

Another area of intense research effort in the Department is computer-aided engineering. Activities in this field include computer-aided analysis (including computational fluid dynamics as well as the finite and boundary element methods), computer-aided design, and computer-integrated manufacturing. Projects include thermal and mechanical analysis of welding and casting processes, heat and fluid flow analyses, stress, deformation (manufacturing processes), vibration and fracture mechanics studies, and solids modelling. Computer-aided engineering is well supported by computer hardware and software, including a state-of-the-art network of engineering workstations. The Department has a substantial involvement in the Manufacturing Research Centre of Ontario.

As part of the faculty interest in transportation, the Department is active in research on air and ground vehicle technology. Current studies include computational methods for steady and unsteady flows over complex configurations; effects of roughness on aerodynamic performance; aircraft noise; boundary layer separation and control; propeller and rotor aerodynamics and noise. The Transport Technology Research Laboratory has been organized for ground transport studies; design and optimization of off-road vehicles; vehicle safety; anti-lock braking systems; vehicle-terrain interaction; effect of vibration on vehicle performance; dynamics of air-cushion and magnetically levitated vehicles and composite and structural elements.

Members of the Department are engaged in research on various aspects of energy conversion, storage, and utilization. In addition to the previously mentioned work on gas turbines, research is being undertaken on nuclear energy, effectiveness of energy end-use, and behaviour in wind of energy-conserving cladding systems for buildings. In the nuclear energy field, research is being undertaken in heat transfer and fluid flow aspects of CANDU and SLOWPOKE reactors, with a major effort on thermohydraulic problems in reactor safety. Work is also in progress on reactor safety in general, with a special emphasis on risk. Research activities in this field also include studies on the utilization of CANDU reactors for thermal energy supply as well as electrical generation, and on applications of up-rated SLOWPOKE reactors to low-temperature industrial heating and to building energy needs. Research is being carried out into the structural integrity of CANDU reactor components in the form of evaluations of non-destructive testing methods suitable for zirconium alloy specimens.

Another area of interest is in design, manufacturing, and materials technology; in particular, there are programs on the properties of welded joints, heat treatment and forming studies.

The departmental laboratories are well equipped for the various research activities described above, and these are supported by a machine shop, electronics shop, and extensive computing facilities mentioned earlier.

The extensive laboratory facilities of the National Research Council, and of the Department of Resources Canada are also used, by special arrangement, for research and graduate studies of mutual interest. Strong contacts are maintained with the gas turbine, aircraft, and nuclear power industries.
