Thermal analysis on the impact of spray charactristics on evaporative cooling process

Journal of Thermal Engineering, 2022
In hot and dry climates, evaporative cooling of the air by water spray can be applied in several requirements, such as evaporative condensers which the airflow is precooled by the water spray before it reaches the condenser. The interaction between water

A wandering spray nozzle

Anaesthesia, 1967
SUMMARY A case is described where a metal nozzle from a lignocaine spray bottle became detached at laryngoscopy, passing unnoticed into the pharynx and oesophagus. It was subsequently recovered at laparotomy from the patient's large bowel where its further progress had been arrested by an obstruction at this site.

Carrier Volume and Nozzle Effect on 2,4-D and Glufosinate Performances in Hazelnut Sucker Control

HortScience, 2020
Hazelnut (Corylus avellana L.) basal sprouts, or suckers, are removed to train trees as a single trunk, facilitating mechanization. Suckers are routinely controlled with herbicides, often by using nozzles that generate fine droplets and spray volumes as ...

Feasibility of Nitrogen as a Carrier Gas for Inconel Cold Spray in Hydropower Application

Advanced Engineering Materials, EarlyView.
N2, despite being nearly two orders of magnitude cheaper than He, is a feasible carrier gas for cold spray Inconel coatings in hydropower repair applications when higher gas temperature and pressure are used. Reducing powder size significantly improved cavitation resistance, while the addition of fine chromium carbide particles further enhanced erosion
