Three-dimensional three-component (3D3C) velocity measurements were made in the flows surrounding a mechanical valve and a silicone polymer valve. Primary three-dimensional flow features were identified in the instantaneous and ensemble-averaged flows surrounding both valves.
In certain mechanical heart valves, cavitation has been shown to develop during closure and rebound, leading to valve damage, blood damage, and strokes. Whereas it is uncertain what causes mechanical heart valve related strokes, some evidence suggests that stable bubbles may be the culprits. Previous work has indicated that vortex cavitation may contribute to stable bubble growth. Therefore, in...
Heart valve-related disorders are among the major causes of death worldwide. Although prosthetic valves are widely used to treat this pathology, current prosthetic grafts cannot grow with the patient while maintaining normal valve mechanical and hemodynamic properties. Tissue engineering may provide a possible solution to this issue through using biodegradable scaffolds and patients' own cells....
Dysfunction of a mechanical prosthetic valve caused by thrombus formation is usually treated surgically. A patient with a thrombosed Björk-Shiley valve in the aortic position was treated successfully with intravenous streptokinase. The considerable improvement in the patient's clinical condition and the phonocardiographic, echocardiographic, and cinefluoroscopic evidence of normalisation of pro...
Clogging of Trash at the Micro Hydro-Power Plant can reduce discharge, head, and micro-hydro production. racks are currently less efficient in solving clogging, so it needs appropriate technology innovation with Horizontal rack Diverter (HTDT) which functions to get rid or divert Trash. Diversion as well increasing stabilizing discharge is important that adding a flow steering valve needed (HTD...
