Influence of an Impinging Jet on Sedimented Debris

18th International Conference on Nuclear Engineering: Volume 3, 2010
The presented work is part of a joint research project performed in cooperation between the Forschungszentrum Dresden and University of Applied Sciences Zittau/Goerlitz. The paper deals with experimental investigations concerning the influence of an impinging jet on sedimented insulation material in the building sump of the reactor containment.

Jet to jet impingement in a confined space

1997
Reaction injection moulding (RIM) is commercially used in industry for making polymer parts. In this process, two or more jets produce impingement mixing of low viscosity monomers or oligomers in a mixhead. In order to better understand an impingement mixer, it is essential to understand the flow field created by the opposed laminar jets in a similar ...

Orifice and Impingement Flow Fields in Confined Jet Impingement

Journal of Electronic Packaging, 1998
The flow fields in the orifice and the confinement region of a normally impinging, axisymmetric, confined, and submerged liquid jet were computationally investigated. Numerical predictions were made for orifice diameters of 3.18 and 6.35 mm at several orifice-to-target plate spacings, with turbulent jet Reynolds number ranging from 8500 to 23,000.

Computations of jet impingement on a flat surface

16th Aerospace Sciences Meeting, 1978
Abstract : An incompressible, inviscid rotational flow model is used to represent the normal impingement of axisymmetric jets and the oblique impingement of two-dimensional jets upon a flat surface. The Poisson-type equation that results from this formulation is cast into suitable finite difference form and solved by relaxation techniques.

Turbulent Flow Characteristics of Aim Impinging JET

Proceedings of the Institution of Mechanical Engineers, 1972
Measurements of shear stress, turbulence energy and other parameters were made in the impingement region of a plane two-dimensional jet confined between parallel walls. Hot wire anemometer arrays were used to examine the turbulance levels in the three directions. The object of the experiments was to make comparisons with a prediction method previously

Impinging Jet Ignition

2018
Turbulent jet ignition can reliably be used to ignite an ultra-lean fuel/air mixture as illustrated in previous chapters. This ignition technique can be utilized in various applications ranging from pulse detonation engines, wave rotor combustor explosions, to supersonic combustors and natural gas engines. Compared to a conventional spark plug, the hot

Characterizing Polymers with an Impinging Jet

Journal of Colloid and Interface Science, 1996
Abstract The impinging jet is a well-established technique to study the deposition of colloidal particles onto a solid surface (a collector) under well-defined hydrodynamic and physicochemical conditions. The presence of polymers, in solution, adsorbed onto the colloidal particles or onto the collector surface, can have a large effect on the ...

Impingement of a liquid jet on an opposing gas jet

Physics of Fluids
In contrast to the existing research on the liquid jet colliding with a physical target to produce a single type of liquid sheet or bell, we used an opposing gas jet target to generate a series of diverse shapes of axisymmetric liquid films. Specifically, we experimentally investigated the outcome of a 0.4-mm diameter water jet impinging on an opposing

Impinging Jet Atomization

2010
This chapter is an introduction to impinging jet atomizers, in which two or more jets are made to impinge on each other. High energy impingement of these jets results in the atomization of the liquid. The chapter provides the theory for the prediction of the sheet formed by the impingement of two jets, followed by estimates of droplet sizes based on ...
