Abstract The bubble–bubble interaction and bubble–needle are usually caused by liquid flow in the needle or needle’s neighborhood. Moreover, nonlinear changes liquid’s velocity pressure can lead to chaotic bubble departures. In present paper, neighborhood were experimentally numerically investigated. experiment, bubbles generated from a brass into distilled water. A second was placed at distanc...

Background: Fluctuations in blood pressure after induction of general anesthesia have played a significant role in complications of surgery. Therefore, the present study was performed by identifying the causes of blood pressure fluctuations after induction of anesthesia, predicting and preventing them. Methods: For this study which is a retrospective cohort, data mining methods in the data set...

Pressure fluctuation may cause high amplitude of vibration of double‐suction centrifugal pumps, but the impact of impeller stagger angles is still not well understood. In this paper, pressure fluctuation experiments are carried out for five impeller configurations with different stagger angles by using the same test rig system. Results show that the stagger angles exert negligible effects on th...
