condensing flows in nozzles and fixed blades of steam turbine have always been the subject of many studies.in such flows, existence of liquid phase in vapor changes the nature of the flow. the major of changes are due to four main mechanisms included nucleation, droplet growth, coalescence and breakage of droplets. in this paper,the effects of coalescence process between droplets have been inve...

The efficiency and emissions of internal combustion (IC) engines are closely tied to the formation of the combustible air-fuel mixture. Direct-injection engines have become more common due to their increased practical flexibility and efficiency, and sprays dominate mixture formation in these engines. Spray formation, or rather the transition from a cylindrical liquid jet to a field of isolated ...

There are many industrial pollutants produced from coal fired power generation plants. Recent legislation is pushing to reduce these emissions. Greenhouse gasses as well as nitrous oxides (NOX) and sulfur dioxide (SO2) are the targeted pollutants. Governmental legislation outlined by Environmental Protection Agency (EPA) through its Maximum Achievable Control Technology (MACT) guideline is a ma...

Abstract Sprays are of great importance for many applications, with drop size being a crucial parameter. Especially in agriculture simple flat fan spray nozzles often supplemented by Venturi component to achieve larger sizes and hence, prevent unwanted drift the smallest droplets. The general believe is that these drops usually attributed fact liquid sheet produced nozzle breaks up more easily ...
