Subject Description

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; understand the principles of operation and optimisation of combustion and air conditioning equipment for improved performance, including the quality of the air environment or work place.

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. Application to heating, cooling, humidification and dehumidification. Combustion. Equilibrium and rate controlled reactions. Ignition, stability and flammability limits; detonation, premixed and diffusion flames. Radiation heat transfer. Pollution control.

Assessment
