Many nuclear power plants report high cycle thermal fatigue in their cooling system, caused by temperature fluctuation in a non-isothermal mixing area. One of these areas is the T-junction, in which fluids of various temperatures and velocities blend. The objective of this research is to classify turbulent jet mechanics in order to examine the flow-field structure under various operating condit...

OBJECTIVE To compare short- and long-term outcome after 180-degree laparoscopic anterior fundoplication (180-degree LAF) with laparoscopic Nissen fundoplication (LNF). SUMMARY OF BACKGROUND DATA LNF is currently the most frequently performed surgical therapy for gastroesophageal reflux disease. Alternatively, 180-degree LAF has been alleged to reduce troublesome dysphagia and gas-related symp...

Turbidity currents in the ocean and lakes are driven by suspended sediment. The vertical profiles of velocity and excess density are shaped by interaction between the current and bed as well as between the current and the ambient water. This paper presents 48 series of experiments in which saline gravity currents flow through a laboratory sinuous flume. flume contains three successive bends wit...
