...ATTACHED JET VELOCITY PROFILES IN MIXING TANKS Leonard F. Pease and Judith Ann Bamberger1 Pacific Northwest National Laboratory Richland, WA ABSTRACT Free jets have been studied in detail over much of the last century, but the theory for offset and attached jets remains incomplete. Attached jets...

... of cavitation of the pumps because of excessive pressure drop. These conditions can be exacerbated with periodic inlet conditions existing at the transfer line inlet. Periodic conditions can result when vessel mixing is intermittent such as with pulsed jet mixers (PJM). The transfer line inlet conditions...

... Abstract In this study, the influence of the direction of the plasma-induced flow generated by a plasma actuator (PA) on the jet flow was investigated. Nozzles equipped with two types of PAs to generate forward (Type A) and backward (Type B) flows were used in this investigation. At a duty...

Paper No: FEDSM-ICNMM2010-30881
... The geometrically similar region of the centerline concentration decay of a counter-flowing jet was investigated using planar laser induced fluorescence. The jet is investigated for jet to counterflowing velocity ratios ( U r ) in the range 4 < U r < 19 . New length scales...

Paper No: FEDSM-ICNMM2010-30684
... In this paper an experimental setup was built to investigate jet flow normal to a confined rectangular multiphase crossflow. In order to achieve uniform particle distribution, the inlet and transition channel were carefully designed and adjusted. The experiments were carried out with 2 test...

... 26 03 2009 When an underexpanded jet impinges normally on a flat plate, the so-called plate shock forms in front of the plate and downstream of the shock the flow spreads radially on the wall. The flow field of underexpanded impinging jet has been studied elsewhere and the shock wave...

... 26 03 2009 A numerical simulation of two-dimensional jets was carried out using a SOLA method. The two-dimensional jets were discharged from a slit in a wall at Reynolds numbers below 50. The difference between the calculated flow fields and those of the Bickley jet is due to the non...

... We consider pulsating jets as one method for the rapid mixing of two different gases. Pulsed carbon dioxide gas was issued from a round nozzle into still air. The intensity of the pulsation was set at the value which produced an oscillatory reversed flow in the nozzle exit. Spatial and temporal...

Flow fields of two dimensional jets impinging on the sharp edge are computationally simulated and the effect of various parameters on the edgetone that is created by the flow interaction is investigated. Compressible Navier-Stokes equations are used so that acoustic waves are captured accurately...
