چکیده انگلیسی


• The modification of effervescent atomizer has been proposed.
• The discharge coefficient depends on the gas to liquid mass ratio.
• Two-phase discharge coefficient depends on discharge coefficient in one-phase flow.
• The highest values of the discharge coefficient were observed for profiled orifices.
• The discharge coefficient for tip of atomizer can be described by proposed equation.

The results of the experimental studies on the atomization process using the effervescent atomizers with the swirl motion flow are presented. A detailed analysis of the effect of the shape of the atomizer on the pressure drops and the discharge coefficient was performed. The inside-out effervescent-swirl atomizers with the cylindrical, conical and profiled orifice were used in the study. The highest values of the discharge coefficient were observed during the atomization with the profiled orifice and the smallest results were noticed for the cylindrical orifice. It was found that when the ratio of gas mass flow rate to the liquid mass flow rate was higher, the shape of the orifice did not play any important role. The equations for discharge coefficient for one- and two-phase flow were proposed. The obtained data is very important especially in the case of designing the effervescent-swirl atomizers.
