  • Overview

    Course outline: This course on thermofluids aims to develop a more advanced understanding of different types of flow. Topics include: application of the conservation of mass, momentum and energy in fluid flow. Benoulli?s equation and the one-dimensional energy equation. Reaction forces due to fluid flow. Buckingham?s ?-theorem and the application of dimensional analysis and similarity for reduced experimentation and scaling. The velocity of pressure waves in pipes. Laminar and turbulent flows in pipes, the Moody diagram. The Pelton wheel, venture meter and orifices. Losses in pipes. Thermodynamics: Second Law of Thermodynamics; heat source and sink; thermal efficiency; reversible and irreversible processes; Carnot efficiency; Carnot heat engine; Carnot refrigeration cycle; entropy; isentropic processes; efficiency of compressors; steady flow devices; isothermal; polytropic and isentropic processes; isentropic efficiencies for turbines, compressors, pumps and nozzles; Gas cycles: Otto; Diesel; Stirling; Ericsson; Brayton; jet-propulsion; vapour and combined cycles; rankine; and refrigeration.
