If the incoming flow from a nozzle is at 90° to a planar metallic surface, then the flow impinges onto the metal surface and moves radially outward. The flow is redirected from being perpendicular to the planar surface to radial parallel to the surface. Mass transport solutions to this situation have been proposed and in general depend upon the ratio of vertical distance to nozzle diameter Hid) and the radial position on the plate (xld) as shown in Fig. 10. Chin and Tsang (4,17) showed that, for Hid between 0.2 and 6 and xld between 0.1 and 1,... 

In the present section, we restrict ourselves to the version of droplet generators working with (mostly metal) nozzle plates carrying the orifice hole(s). The design of the nozzle plate concerns both the diameter and the shape of the... 

Metal powder production and spray-forming (Figure 38a) both involve the blowing of a metal stream with a jet of gas. The size distribution in both these processes is a key factor and it has been found that this is dependent inversely upon the Weber Number (We = v2Dp/y) where v = velocity of gas, D = nozzle diameter p = density and Y = surface tension. Thus the particle diameter has a direct dependence on the surface tension (Figure 8b) and an inverse dependency upon the S content of the alloy. 

Ceramic, plastic and other non-metal tower shells are used quite often (Figures 9-3, 4, and 5). It is important to consider in ceramic construction that the main inlet or outlet nozzles or any other large connections should be oriented 90° to each other to reduce the possibility of cracking the walls, as most cracks go one-half diameter. Preferably there should only be one nozzle at any one horizontal plane. The nozzles should never carry any piping or other stress load.

Fig. 1. Detail of reaction zone of the metal-atom reactor. Suitable reactor dimensions are 15-18 cm diameter, 5 mm wall thickness and 36-46 cm depth. The water-cooled electrodes are 7.5 cm apart. The central substrate inlet tube, a 6 mm od Pyrex slightly constricted at the end, extends 5 cm below the liquid nitrogen level. A 14 mm od Pyrex tube which serves as a substrate deflector is positioned 5 cm below the inlet nozzle and is suspended horizontally between the electrodes. A built-in Pyrex syphon tube extends to the bottom of the reactor for the removal of air sensitive products under an inert atmosphere.
