Co-axial two impinging streams

To make sampling easier, the open horizontal co-axial two-impinging stream device is employed in the experiments, as shown in Fig. 5.1. 

Kostiuk et al. [40] measured experimentally the flow field of the vertical co-axial turbulent impinging streams with a two-component Laser Doppler velocity meter. The opposing gas streams were ejected from two burner nozzles, which were designed to produce a uniform axial velocity profile at their exits. The turbulence in the flow was generated by a perforated plate located at the end of the contraction section in each nozzle. The air velocity at the exit of the nozzle was varied from 4.1 to 11.4 m s and...

The structure of the circulative impinging stream dryer developed is sketched in Fig. 6.13, in which the flow configuration of vertical two impinging streams is employed. The equipment consists of three basic parts mounted co-axially the body, the upper and the lower accelerating tubes. The body is of a conical/cylindrical shape with different diameters. The lower-middle part of the body is a cylinder with a relatively... 

Champion and Libby analyzed both the planar two-dimensional impinging streams and the impingement of two co-axial-cylindrical jets in which the flow is axis symmetrical. Actually, the results they obtained are applicable for both the two cases, provided the two-dimensional coordinates in planar impinging streams are replaced by the cylindrical coordinates.
