This course is designed to illustrate the application of basic principles of fluid dynamics and thermodynamics to various kinds of turbomachinery. The feature of axial Turbine (Gas and Steam) and Compressor are discussed as well. The Radial Compressor, Pumps and Turbine are treated as well taken into account the specific characteristics. An understanding of fundamental physical principles as they are applied to the design and analysis of axial and radial compressors, pumps, fans, and turbines, to produce rational design methods. The following content will be included:1.Demonstrate comprehension of the necessary basic principles of fluid mechanics and thermodynamics such as covered in Thermodynamics and Fluid Flow. 2.Demonstrate comprehension of the Euler Turbomachinery Equations, derive from the angular momentum equation, and apply to problems encompassing the operation of the basic elements of turbomachinery. 3.Apply the conservation equations of mass momentum, and energy in relative and absolute coordinate systems to determine the ideal mean-line performance of turbomachine elements. 4.Demonstrate and apply comprehension of the viscous and compressible effects responsible for non-ideal performance in turbomachines. 5.Apply performance models to estimate non-ideal performance for design and analysis of turbomachine elements. 6.Demonstrate and apply comprehension of the fluid mechanics responsible for limits of turbomachinery operability and stability, particularly, stall, surge, cavitation, and choke.7.Appreciate the use of laboratory and testing methods, and the value of quality data in design and development. The students are expected to master the basic characteristics of radial and axial pumps, compressors, turbines and fans with different kinds of working mediums.
