초록

The Ejector is used to get low pressure, and it has been applied to a lot of industry field like the heat engine, the fluid instrument power plant, the food industry, environment industry etc... because there are not any problem even it is mixed with a any kind of liquid, gas, and solid. The flow characteristics in ejector are investigated by PIV and CFD. The experiment using PIV measurement for mixing pipe’s flow characteristics acquired velocity distribution, .Condition : when mixing pipe’s diameter ratio is 1:1.9, and the flux is $Q_{1}=1.136\;l/s$, $Q_{2}=1.706\;l/s$, $Q_{3}=2.276\;l/s$. Based on the PIV and the CFD results, the flow characteristics in ejector are discussed, and it shows the validity of this study.
