Venturi tube is one of key equipments in process of purification and recovery of converter gas, which is used to drop temperature of converter gas with sprayingjet fixed at throat of Venturi tube.
That means that the jet can fly at a relatively high 600 to 800 feet spraying its payload as it goes, making it safer in theory, even suitable for firefighting at night.
In the cold gas dynamic supersonic powder spraying technology for material modification, the two phase turbulent numerical computation of the jet field is very important.
