Experimental Study on A Swirl-vane Steam Separator with Air-Water

Small scale swirl-vane steam separator is experimentally studied by high speed camera,using air-water modeling fluid.The experimental result shows that the thickness of the water film on the inner tube is vital to the separation.The separation efficiency is mainly influenced by the water flow rate.It rises gradually due to the increase of the water film thickness and the reduction of the water droplets with the increasing of water flow rate.The incensement declines when the water flow rate is larger than 0.3m³/h,and furthermore it decreases.The reason is that the water film is distorted to be droplets by the high speed air due to reducing flow area for air.
