Abstract:
In one embodiment, a mixing device includes a nozzle that is disposed tangent to a wall of a chamber. Gas flowing from the nozzle rotates in the chamber forming a vortex. Another gas may be flown near a middle portion of the chamber, thereby uniformly mixing the two gases. In another embodiment, an evaporation and mixing device includes a nozzle configured to impart rotation to a gas flowing into a chamber. An injector flows a liquid material near a middle portion of the chamber, thereby mixing the gas and the liquid material. A heater may be employed to help evaporate the liquid material.
