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

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.

A gear pump and a centrifugal spray nozzle were used in the encapsulation unit. 0.8% and 1% sodium alginate were obtained for the encapsulated material. The capsules obtained in a concentration of 1% sodium alginate during the experiment were rounded and homogeneous, soft but stable under physical influence, and had an average diameter of 1,2×10-3м. To get one kilogram of mk capsules, it is necessary to take Vz=1,404·10-3 м3 from the volume filled with capsules. This corresponds to the set productivity per hour. Turbulent motion is characterized by continuous mixing of liquid particles. Basica

Abstract:

This paper presents the design and experimental evaluation of a throttleable pintle-centrifugal injector system tailored for hybrid rocket engines, aimed at improving combustion efficiency and enabling precise throttling control. The novel injector system combines the principles of swirl injection and pintle-based throttling, offering fine adjustment of oxidizer flow rates to optimize combustion dynamics. Cold-flow experiments using deionized water were conducted to assess the injector’s performance across a range of flow rates and pintle strokes. Results demonstrate that the pintle stroke eff

An experimental etcher – inlayer of potato tubers is proposed, containing a chamber for coating tubers with a liquid preparation, with a sieve and a centrifugal spray installed in it, and a chamber for coating with a powdered preparation. A model that is as close as possible to the real process is constructed and justified, a visualization of the process is obtained on its basis, and optimal operating modes are established. Conclusions are given based on the research results.

Abstract:

The paper presents the results of mathematical modeling, numerical and laboratory experiments aimed at developing an optical method for estimating the size distribution of droplets in a spray. The optical method is based on analyzing the brightness of light reflected by drops of a liquid. The ob-ject of study was a spray of a transparent liquid (distilled water) produced by a centrifugal axisym-metric nozzle. It is known that the intensity (brightness) of light reflected by a drop is proportional to the surface area of the drop, and for spherical drops, accordingly, to the square of the drop’s

Abstract:

Water pressure problems at home can be quite frustrating in daily life which is comes in different ways of complication. It may take forever for the faucets to fill a bathtub, or a slow spray shower head and longer time taken for the washing machine to run a cycle. The problem can be fixed by installing a pressure booster pump. This research is embarked to study on a centrifugal pump performance with a view to analyse pressure built-up and flowrate in pipe at fixed speed. A simple and inexpensive test rig is developed to resemble water distribution for domestic use; i.e. house application. The

ABSTRACT Tractor traveling speed can influence the quality of spraying depending on the application technology used. This study aimed to evaluate the droplet spectrum, the deposition and uniformity of spray distribution with different spraying systems and traveling speeds of a self-propelled sprayer in two phenological stages of the cotton plant (B9 and F13). The experimental design was randomized blocks and treatments were three spraying techniques: common flat spray tips; tilted flat jet with air induction, at 120 L ha-1; and rotary atomizer disk, 20 L ha-1, combined with four traveling spee
