This paper presents the results of a research on dispersion of water spray of centrifugal spray nozzle. The values of average droplet size are defined and compared with the known one calculated before. There were made graphics of drops dispersed distribution and graphics where the experimental and calculated values for the arithmetic mean and median mass diameter. The obtained data allow to recommend the calculated dependencies for the assessment of medium-sized drops in the spray of centrifugal-jet spray nozzle.

Abstract:
Centrifugal nozzle is an important part of an areoengine in which fuel atomization has strong influence on engine performance. For investigating the fuel spray characteristics, a promising method named off-axis particle holographic measuring system is used here. Characteristics of the nonevaporating spray ejected from a new type of centrifugal nozzle which would be used in the near future are obtained under various injection conditions. By automatic analysis of the holographic reconstructed droplets images, a hollow-cone shape spray with most droplets concentrated in the surface of the cone is

In the present study, the effect of microstructure on the wear characteristics of spray cast Al-15Si and Al-20Si alloys has been investigated and compared with that of vertical axis centrifugal cast and chill cast alloys. The spray cast alloys have been subjected to Hot Isostatic Pressing for porosity reduction. HIPing has reduced the porosity in the spray cast Al-15Si and Al-20Si alloys from 19% to 8% and 19% to 2% respectively. The microstructures of spray cast alloys consisted of finely divided globular shaped Si particles with sizes varying from 2–10 µm. The Si particles have been distribu

Abstract:
The COVID-19 pandemic imposes a severe challenge to the health care providers and patients in dental clinics as the dental procedures produce abundant airborne materials. Although dental practices use a multi-layered protective procedure to reduce the potential danger from dental aerosols, it is still beneficial to suppress the aerosol generation from the origin as much as possible. Reducing the aerosol generation (especially the droplets of smaller diameters) from the very beginning will ease the burden on all subsequent layers of protection.

Abstract:
Modern oil field pumps are widely used in drilling and operation of wells. Most of the pumps used in drilling oil wells are centrifugal pumps. Centrifugal pumps fail for many reasons after a long period of operation. One of the most important parts of these pumps is the impeller. Impeller failures lead to stoppages in centrifugal pumps. In order to prevent stoppages, it is necessary to increase longevity and extend the time between repairs, eliminate malfunctions in the impeller. The main causes of failure are vibration and cavitation, corrosion and wear in the pump. The article concerns the p
