Experimental studies of frequency of rotation of smooth rotating disk with coaxial-lateral air flow

Abstract

The article presents methods for determining the main parameters of a rotating atomizer sprayer. The choice of research methodology is justified based on the general pattern of liquid atomization by rotating atomizers, taking into account the influence of the air flow on them. The main indicators affecting the sprayed drops' dispersal are the air flow rate and the rotational speed of the pneumatic disk atomizer. Therefore, the correct choice of the method for determining the rotational speed ω of a pneumatic disk atomizer makes it possible, at a constant air flow rate, to obtain the required median-mass diameter of the atomized droplets. To obtain a high-quality air-droplet flow, there must be a combination between the initial speed of the main drops discharged from the spray disk's periphery and the fan installation's air flow speed.

Technical means for collecting seeds of desert-pasture fodder plants

“…• the slats of the reel are increased with elastic material, the whip drum of the threshing apparatus is replaced with a pin drum • the lower part of the straw walker keys is covered with steel sheet slats When harvesting seeds with a pick-up grinder, the seed plants are preliminarily mowed into rolls and dried [8][9][10].…”
