摘要：

This paper draws a link between the liquid viscosity and the spray angle for effervescent and effervescent-swirl atomizers. The spray angle determines the dispersion and coverage area of the resultant sprays. The swirling the gas-liquid mixture in atomizer led to a significant increase of the spray cone angle at low gas to liquid ratio by mass. Additionally, the orifice shape plays an important role in obtaining the spray angle. The highest values of spray angle has occurred during atomization using profiled orifice. Mathematical analysis shows that spray angle depends on the liquid viscosity, the gas and liquid flow rates and the construction of the atomizer. The data obtained are very important from point of view of the design of atomizers and coverage area of spray. (C) 2015 Elsevier B.V. All rights reserved.
