436-432 Thermofluids 4

436-352 Thermofluids 3 or equivalent

Upon completion, students should have gained the ability to analyse and design a wide range of fluid mechanical devices and comprehend several fundamental engineering problems through analysing and studying boundary layers and turbulence; and understand the principles of operation and optimisation of combustion and air conditioning equipment for improved performance, including the quality of the air environment or workplace.

Topics covered include wing theory: Prandtl lifting line; three-dimensional effects; aircraft performance; propellers, jets and fans and pumps; waves, ship resistance; model testing; wave resistance, ocean waves; boundary layers: Navier-Stokes equations; Prandtl's assumptions; Laminar solutions; Von Karman's momentum integral equation; transition; turbulence; turbulent boundary layers; turbulent flow in pipes and ducts; mass transfer, air conditioning and refrigeration; applications to heating, cooling, humidification and dehumidification; combustion; equilibrium and rate controlled reactions; ignition, stability and flammability limits; detonation, premixed and diffusion flames; radiation in combustion; and pollution control.

Two 1.5-hour examinations (75%); assignments and laboratory reports not exceeding 20 pages including computations, diagrams, tables and computer output (25%). Students will be notified of the weighting of the non-examination assessment components at the beginning of semester.
