Studies from Singapore, the South Korea and Germany add new findings to medical devices body of knowledge
Published in Heart Disease Weekly, November 12th, 2006
Study 1: The squeeze flow phenomenon through the mechanical heart valve (MHV) is a likely source for potential cavitation.
According to a study from Singapore, "Fluid between the reducing flow channel of the valve occluder and the orifice wall tends to be squeezed out of the flow channel, causing a high-speed flow. The squeeze flow is accompanied by a sharp local pressure drop, which may result in potential cavitation phenomenon in a MHV. Limited experimental investigation has been conducted into the flow physics of this squeeze flow phenomenon, which is...
