Granular jet impingement on a fixed target.
In 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. 93, 188001 (2007)] provides interesting insights in the theoretical ...
متن کاملRarefication Effects on Jet Impingement Loads
Rarefication effects on jet impingement loads are studied by comparing recent new formulas at the collisionless flow limit and numerical simulations. The jet exit size is finite, and can be either planar or round. In the simulations, the jets have different degrees of rarefication, with a Knudsen (Kn) number ranging from 0 to infinity; i.e., the jet flows can be continuum, collisional, or colli...

TECHNICALNOTES are shortmanuscript s describing new developments or important results of a preliminary nature. TheseNotes cannot exceed sixmanuscript pages and three gures; a page of text may be substituted for a gure and vice versa. After informal review by the editors, they may be published within a few months of the date of receipt. Style requirements are the same as for regular contribu...
متن کاملHighly rarefied two-dimensional jet impingement on a flat plate
In this paper, we investigate highly rarefied jet gas flows out of a two-dimensional slit that impinges on a flat plate which is set vertically to the plume flow direction. The plate is assumed to be completely diffusive and the gaseous plume flow out of the slit is modeled with a Maxwellian distribution function which is characterized with known number density, nonzero exit velocity, and tempe...
متن کاملImproving Cyclone Efficiency by Recycle and Jet Impingement Streams
In this paper a new process is presented for improving efficiency of cyclone de-dusting systems. The cyclone is coupled with a specially designed cylindrical chamber which includes a rotating tube inside it with air impinging nuzzles, drilled on the peripheral surface of the tube. The nuzzles help in pushing and throwing the particles to the outer radius distances during downward flow of du...
