Gas Conditioning Towers

Spray Tower Design:
Water droplets are injected into a hot gas stream to cool the flow. It is critical to obtain complete evaporation of the water droplets while optimizing the uniformity of the gas velocity and temperature within the spray tower.

Spray Tower Droplet Evaporation
Baseline Droplet Trajectories

In this baseline case (above, right), three dual-fluid nozzles inject water at the top of the tower. Using droplet size information provided by the nozzle manufacturer, the CFD model tracks the droplet trajectories while calculating the droplet evaporation, gas temperature, and concentration of water vapor released by the droplets. Unfortunately, evaporation of the largest droplets is not complete and they exit the tower.
