The susceptibility of the primary coolant boundary components of the MW(e) gas-cooled fast breeder reactor (GCFR) Flow-induced vibrations in the 300-MW book plant to flow-induced vibrations is analyzed. This preliminary analysis is based on the reference design. In the past, several MW steam turbine rotors were affected by vibrations, which appeared at bearing #1 during load conditions.

At certain loads, vibrations of the #1 bearing increased. The modeling of fluid–structure interactions, such as flow-induced vibrations, is a well-developed field of mechanical engineering. Many methods exist, and it seems natural to apply them to model the behavior of plants, and potentially other cantilever-like biological structures, under flow.

Overcoming this disciplinary divide, and the application of such models to biological systems, will Cited by: L. J Halvers has written: 'Flow-induced vibrations in the MW(e) gas-cooled fast breeder reactor demonstration plant' -- subject(s): Gas cooled reactors, Vibration Asked in Physics, New.

Introduction. Vibration of equipment has been a severe problem in Hydro Power Stations (HPS) from the very beginning of power generation. Failure of the equipment due to vibration causes shut down, or sometimes, even a disaster in hydro power station (HPS).VCM has to be done to examine the performance of such equipment online automatically and to know the status of complex systems in Cited by: 6.

Then, the catastrophe performance analysis is conducted for a MW subcritical steam turbine. The rules of catastrophe are discussed, and the system's catastrophe areas are divided. It is discovered that the system catastrophe will not occur until the impact factors satisfy given by: 2.

A cylindrical core of a Gas Cooled Reactor (GCR) with total thermal power MW and fuel assemblies has dimensions R = m and H = 9 m. Assuming the extrapolation length d = m, calculate: (a) the mean power density in the core, (b) the maximum power density in the core.5/5(1).

A variety of studies have assessed methods to convert flow energy into vibration. These include vortex shedding [8,9,10,11,12], flapping motions [], hydraulic pressure [], and impeller structures [15,16].The approach we are investigating consists of a cantilever mounted in an internal flow channel where either the cantilever itself is a piezoelectric bimorph, or a non-piezoelectric cantilever Cited by: There is an Open Access version for this licensed article that can be read free of charge and without license restrictions.

Absorption of ultrasonic energy leads to tissue heating, and this has been used with therapeutic intent in many conditions.
