BACKGROUND The total cavopulmonary connection (TCPC) design continues to be refined on the basis of flow analysis at the connection site. These refinements are of importance for myocardial energy conservation in the univentricular supported circulation. In vivo magnetic resonance phase contrast imaging provides semiquantitative flow visualization information. The purpose of this study was to un...

In this paper, A numerical study has been conducted to predict the hydrodynamic characteristics of the staggered ribbed backward facing step flow with inclined impinging jet. The impinging jet flow was inclined towards the main cross flow and the angle of inclination is ranged from  30 to  90 . The ribs were in staggered arrangement and aligned after the slot jet in normal direction to the ma...

Numerical simulation has been performed by solving full Navier–Stokes equations governing the three-dimensional unsteady compressible flows. The main goal of the present work is to investigate the flow characteristics of a square jet issuing transversally into a cross-flow at three injection angles of 90°, 60° and 30°, and thus to provide some deeper insights into the physical flow mechanism go...

The flow control on the separation bubble and the large scale vortex is important in the turbo machine. Recently, a new approach using the plasma actuators is proposed to control the separation bubble and the large scale vortex. The aim of this study is to control the large scale vortex behind a flat plate using the plasma actuators. The effect of the three dimensional jet induced by the plasma...

many experimental studies have been conducted on development of the scour hole as a result of vertical jet impaction. research has shown that aeration of the nappe flow in the model is much weaker than that in the prototype. therefore, the influence of aeration on scour holes needs further study. experimental investigation of the effects of air entrainment and tail water depth on the scour hole...

Impinging jets are used in various in cooling and drying technique. The current research the means of improving the heat transfer for con minimum distance of the nozzle to the impingem impingement heat transfer is described using nume a wide range of parameters for an array of p parameters include varying jet flow speed, width o of nozzle, angle of the jet flow, velocity and impingement surface...

sudden pipe expansions have been known as efficient hydraulic energy dissipaters for a long time. the complex phenomenon of flow separation and velocity discontinuity at the interface of incoming jet and the recirculation flow, results in intensive shear and tensile rupture of the fluid and the associated destructive phenomenon of cavitation. this paper focuses on aeration in sudden pipe expans...

Accumulation of large, high-quality satellite and in situ data led to significant improvements in the description of the mean dynamic ocean topography (MDOT) [6]. The new models of MDOT, with the resolution improved to 50-100 km, have not only revealed important details in the complex mesoscale structure of circulation systems such as the Gulf Stream, Kuroshio Extension, and Antarctic Circumpol...

Analytical solutions for the problem of radiation of sound from a duct with flow have been shown to serve as an important first model for acoustic engine-aircraft engineering applications, useful for understanding the physics and for validating and benchmarking numerical solutions. The probably most important steps were taken by Levine & Schwinger and Munt. He showed that application of the Kut...
