FLUID MECHANICS II (SEMM 2323)

COURSE INFORMATION
Open or CloseThis course is designed to enhance the basic knowledge that has been developed in the first stage of Fluid Mechanics I (SKMM 2313) and expose the students in analysing hydrodynamically the flow field. It will emphasize on the analysis and the importance of ideal, boundary layer, and compressible flow in a practical engineering applications. The course will also provide the analysis of flow through fluid machines such as pump and turbine. At the end of the course, students should be able to demonstrate and apply the theory to solve problem related to flow of fluids.
COURSE LEARNING OUTCOMES Calculate fluid dynamics problems using differential forms of the fundamental laws. Deduce expression for stream function and velocity potential for elementary flows and various superposition of these elementary flows using the inviscid theory. Determine pressure and velocity of these flows.
 Derive expression of boundary layer flow using Von Karman momentum integral equation for laminar and turbulent flow. Calculate drag for flow around flat plate.
 Develop a set of governing equation and calculate flow process for 1D compressible flow across normal shock through convergencedivergence nozzles.
 Illustrate basic function of a pump and turbine, its working principle and function of its major components. Calculate the efficiency of centrifugal pump, Pelton wheel and Francis turbine.
 Design and analyse fluid mechanics components and/or systems based on given specifications.
