    Professor Emeritus of Mechanical Engineering


    Education and Experience

    B.E. (1961) and M.Sc. (1963), University of Saskatchewan, P.Eng.


    1. Professor Hertz is a licensed consulting engineer with the Association of Professional Engineers and Geoscientists of Saskatchewan (APEGS).
    2. Hertz is also a registered consulting engineer with the Professional Engineers of Ontario (PEO). His technical memberships include the Society of Tribologists and Lubrication Engineers (STLE), and membership in the Society of Automotive Engineers (SAE).
    Specialization: Vehicle Research, Machine Design, Manufacturing, Mechanical Tribology

    Current and Past Projects

    1. Vehicular transportation efficiency
    2. Vehicle aerodynamics
    3. Wind tunnel testing
    4. Machine Design: Automotive Vehicles
    5. Mechanical Tribology: Friction, Lubrication, & Wear
    6. Alternative Fuels and Lubricants
    7. Bio-Diesel Engine Wear Research
    1. Mechanical Tribology: The current emphasis is to reduce diesel engine wear by employing bio-diesel fuels and fuel additives as lubricity enhancers. A Roller on Cylinder Lubricity Evaluator (M-ROCLE) testing machine has been developed for fuels and lubricants. Correlations between ROCLE fuel lubricity numbers and diesel engine wear rates, as determined from lubricating oil analysis, are currently being conducted.
    2. Vehicle aerodynamics and wind tunnel model studies: The object of this work is to develop efficient road vehicle shapes capable of extracting propulsive energy from prevailing cross-winds. A series of U of Sask. super mileage cars based on these yaw-thrusting principles enabled numerous fuel economy records to be broken during the 1980's. The current emphasis is to adapt these plan-view airfoil shapes to low aerodynamic drag truck and bus configurations.
