متن کاملFlow Instabilities in Cavitating and Non-Cavitating Pumps
It is well known that flow instabilities called rotating stall and surge may occur in non-cavitating turbomachines at flow rates smaller than design. Rotating stall is a local instability at the turbomachinery which is basically not dependent on the hydraulic system in which the turbomachine is installed. The stalled region rotates faster than impeller. Surge is a system instability in a hydrau...
متن کاملPrimary pulmonary cavitating carcinomas.
A primary lung cancer can produce a cavity in three ways. The first is 'cavitary necrosis' due to breakdown of the growth itself. The second is 'stenotic abscess' due to infection and breakdown of the lung parenchyma distal to bronchial obstruction caused by the growth. The third type is 'spill-over abscess'. In the present series, necrosis and cavitation were observed in 100 cases out of a tot...
متن کاملInfected cavitating pulmonary infarction.
The differential diagnosis of pulmonary cavitation is broad. The most common causes include infection and malignancy. Pulmonary thromboembolism is a common problem worldwide, with an estimated 650,000 cases in the United States annually. Pulmonary embolism does not usually lead to cavitation, given the dual blood supply of the lung; however, cavitation may complicate 4–7% of all pulmonary infar...
