Valves are widely used in various working conditions for their flow control functions, and the
cavitation inside valves has been investigated owing to its harm to the valve itself and the …

Cavitation was first directly related to mechanical heart valves in the mid 1980s after a series
of valve failures observed with the Edwards–Duromedics valve. The damages observed …

The presence of vortical flow structures that develop inside different cardiac chambers is
shown to correlate with functional status of heart, and significantly affects the cardiac …

Total dissolved gas (TDG) supersaturation from sources such as hydroelectric dams can
cause harmful bubble growth in the tissues of aquatic animals, known as gas bubble trauma …

A major drawback in the operation of mechanical heart valve prostheses is thrombus
formation in the near valve region. Detailed flow analysis in this region during the valve …

Cavitation has been shown to play a key role in a wide array of novel therapeutic
applications of ultrasound and lasers. Sometimes the mechanical effects associated with …

In this study, the closing dynamics of two im**ing rods were experimentally analyzed to
simulate the cavitation phenomena associated with mechanical heart valve closure. The …

The objective of this study is to propose a modified method for the cavitation model and
turbulence model, accounting for the influence of vortex motion on unsteady cavitating flows …

A computational fluid dynamics (CFD) methodology is developed to assess the
hydrodynamic and hemodynamic performance of a positive displacement left ventricular …

Due to expensive nature of clinical trials, implantable cardiac devices should first be
extensively characterized in vitro. Prosthetic heart valves (PHVs), an important class of these …
