METHOD AND NOZZLE FOR PROVIDING A FLOW WITH SEPARATED GAS AND LIQUID PORTIONS SUBJECTED TO AN ACOUSTIC FIELD

摘要

A method of providing a gas/liquid jet having finely atomised liquid droplets comprising the steps of feeding a mixture of gas and liquid into a tube (5) provided with at least one outlet nozzle (6) having an outlet opening. A plug flow (i.e. a flow in which liquid portions and gas portions are separate from each other) is formed in the tube (5) before the flow leaves the nozzle (6). The outflowing plug flow is subjected to an acoustic field, the frequency of the plug flow thereof essentially being a multiple of the frequency of the plug flow and preferably close to the frequency thereof.
