Formation Principle and Characteristics of Self-Supercharging Pulsed Water Jet
Chinese Journal of Mechanical Engineering, 2022 High-pressure pulsed water jet technology has considerable development potential in the field of rock fragmentation. To overcome the shortcomings of existing pulsed jets, a self-supercharging pulsed water jet (SSPWJ) generation method is proposed, which ...

Shock-induced collapse of a gas bubble in shockwave lithotripsy [PDF]
, 2008 The shock-induced collapse of a pre-existing nucleus near a solid surface in the focal region of a lithotripter is investigated. The entire flow field of the collapse of a single gas bubble subjected to a lithotripter pulse is simulated using a high ...

Cardiac Pressures and Pulses. [PDF]
Archives of Internal Medicine, 1957 This small book by Luisada and Liu summarizes in 109 pages aspects of hemodynamic cardiac phenomena obtained by cardiac catheterization with the Fick principle for recording variations in cardiac output and pressure. The monograph includes a discussion, in more or less conventional fashion, of the cardiac cycle, technique of catheterization, normal ...

Pressure Pulse in Small Arteries [PDF]
Circulation Research, 1962 Pressure pulse contours have been obtained in the small mesenteric and intestinal arteries of the dog. The principal change in the pressure pulse during transmission from large to small arteries appeared to be the gradual and progressive development of damping. The pressure drop from the aorta to arteries of 200 µ internal diameter averaged 17 per cent
