Studies in experimental shock

Experimental Studies of Shock Diffraction

Diffraction of a normal shock wave has been the subject of numerous studies, dating back work of Whitham [1]. A large number of the complex flow features present were highlighted in the well known work by Skews [2]. Fig. 1 shows the flow features behind a strong shock diffracting around a sharp corner. Skews showed that for angles greater than 75o the flow features become independent of the cor...

Innovations in shock wave lithotripsy technology: updates in experimental studies.

PURPOSE We developed innovations in shock wave lithotripsy (SWL) technology. MATERIALS AND METHODS Two technical upgrades were implemented in an original unmodified HM-3 lithotriptor (Dornier Medical Systems, Inc., Kennesaw, Georgia). First, a single unit ellipsoidal reflector insert was used to modify the profile of lithotriptor shock wave (LSW) to decrease the propensity of tissue injury in...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Shock lung--experimental studies on a haemorrhagic hypovolaemic rabbit model.

An experimental model of haemorrhagic hypotension was standardized using rabbits to investigate the shock lung syndrome over a period of 120 minutes. Acute hypovolaemia was induced by withdrawal of blood under anaesthesia to a mean arterial pressure of 30 +/- 5 mmHg within 10 minutes. The mean leucocyte counts and the release of lysosomal enzymes (acid phosphatase and beta-glucuronidase) in the...
