I am retaking Orgo1 for this semester. Compared to the previous lecturer, Dr Wang makes 2201 bearable and I enjoyed most of his lectures. Orgo is always tough and overwhelming (the nature of this subject). But Dr. Wang is very organized and strictly follows the book. His test questions came directly from the lecture notes and book problems.

1. Introduction and noise. With the development of high-speed and large-scale pumps, especially high energy density, high requirements have Pumps are essential machinery in the various industries, espe- been imposed on the vibration and noise performance of pumps,cially in nuclear power plant systems, energy storage heat exchange and cavitation is an important source of vibration and noise exci-system, high-performance liquid rocket engine turbopump and tation in pumps. Due to the negative effect of cavitation on theship water-jet propulsion device. When cavitation occurs in the pump performance, it is necessary to improve the cavitation per-pump, it will also result in surface metal erosion of the hydraulic formance of the pump. Currently, the rapid cavitation predictioncomponents. The surface erosion reduces the energy delivery effi- method is lacked for the pump optimization.The cavitation phe-ciency and causes high maintenance costs. The performance nomenon includes the phase transition process and the large-scaledegradation of the pump will also affect the stability of the pump vortex of the vapor phase and the liquid phase. Katz [1] found thatsystem, and serious threat to the safety operation. Generally, the axial shear vortex structures have an effect on the development ofdesign of the pump mainly ensures high efficiency at high speed by cavitation in the separation region. Laberteaux [2] used high speeddesigning the impeller and the diffuser, and at the same time meets photography to observe the cavitation eddy flow structures in thespecial requirements such as strong anti-cavitation, small vibration closed area of the attached cavitation. Cavitation flow is a complex unsteady two-phase turbulent flow with very complex mass, mo- mentum and energy exchanges between the bubble and the liquid.
