He is an inventor on several patents relating to rotating machinery and vibration. Whirling (translational) and precession (tilt) motion of the shrouded centrifugal impeller are possible vibration sources that can cause rotordynamic instability problems. Whirling motion of shrouded impellers and seals has been investigated by test and theory in the literature.

The infinitesimal method is then applied to obtain the rotordynamic coefficients, which agrees well with published experimental results for both labyrinth seals and eccentric smooth annular seals.

Particularly, the stability parameter of the effective damping coefficient can be solved precisely. I was not aware of your research until Dr. Iino, Mechanical Engineering Research Laboratory of Hitachi, told me what he saw after he returned from NASA Workshop on Rotordynamic Instability Problems in High Performance Turbomachinery held at Texas A&M Uni.

Ohashi H and Shoji H Lateral fluid forces acting on a whirling centrifugal impeller in vaneless and vaned diffuser Workshop on Rotordynamic Instability Problems in High Performance Turbomachinery (NASA Conf. Publ.) Describes the rotordynamic considerations that are important to the successful design or troubleshooting of a turbomachine.

Shows how bearing design, fluid seals, and rotor geometry affect rotordynamic behavior (vibration, shaft whirling, bearing loads, and critical speeds), and describes two successful computational methods for rotordynamic analysis in terms that can be u/5(6).

The book provides a detailed approach to the physics, fluid dynamics, modeling, experimentation and numerical simulation of cavitation phenomena, with special emphasis on cavitation-induced instabilities and their implications on the design and operation of high Manufacturer: Springer.

As a result of these substantial technical advances, new high-performance turbomachinery was designed, developed, and put into service to operate at higher speed and higher energy density level. A rotordynamic analysis is mandatory to avoid vibration resonance and instability at high speed.

The critical speeds of a turbopump are defined as coincident to the shaft rotating speed and the rotating natural frequencies of the rotordynamic system.Machinery Vibration and Rotordynamics: Combines rotordynamics with the applications of machinery vibration in a single volume Includes case studies of vibration problems in several different types of machines as well as computer simulation models used in industry Contains fundamental physical phenomena, mathematical and computational aspects, practical hardware considerations.
