Jet to jet impingement in a confined space
1997Reaction 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 ...

On unsymmetrically impinging jets
Journal of Fluid Mechanics, 1990Two impinging two-dimensional incompressible inviscid fluid jets of known widths and velocities produce two outgoing jets. The speeds of the outgoing jets are readily determined from the Bernoulli equation. Their two widths and two directions (four quantities) are related by conservation of mass and conservation of two components of momentum (three ...

Granular jet impingement on a fixed target
Physical Review E, 2010In this work discrete element modeling (DEM) was applied to the flow of granular jets against a target. The resulting sheetlike or conelike formations under different conditions are described and explained by means of kinetic analysis. A qualitative and quantitative comparison with experimental results [Cheng, Phys. Rev. Lett.

Study on Compulsive Cooling of Straight Impinging Jet Array and Swirling Jet Impingement
2006 International Conference on Electronic Materials and Packaging, 2006Impinging jet is one of the ideal schemes to satisfy the heat dissipation requirement of the high power chips. In this research, experiments are carried out to investigate the heat transfer between the straight impinging jet array and an iso-heat-flux simulant chip (a heated epoxy resin plate).

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 ...

Computations of jet impingement on a flat surface
16th Aerospace Sciences Meeting, 1978Abstract : 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.

Orifice and Impingement Flow Fields in Confined Jet Impingement
Journal of Electronic Packaging, 1998The 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.

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
