Spray columns and towers are fundamental in many industrial applications. Understanding the spray pattern in these dynamic environments is very important in the design of an overall spray system solution. Traditional laboratory physical experiments can be time-consuming, expensive, and sometimes impossible to complete. Computational fluid dynamics (CFD) modeling can be used effectively in this area.
In this case study, a slurry feedstock is injected into a reaction column through numerous no

Refineries are required by law to reduce the emission of nitrous oxides (NOX) to the atmosphere. Spray nozzles are key components in the gas conditioning equipment used to control the humidity and temperature of the gases, providing controlled volumes of liquid with predictable drop size and consistent spray coverage. Knowing these values is vital for the optimization of gas conditioning processes.

In addition, the placement of nozzles is often times misunderstood and therefore inaccurate. W

In many industrial processes, hot gas is cooled down due to the evaporation (boiling) of sprayed droplets. The effects of two different atomizer types, inner mixing air atomizing nozzles and flow back nozzles, on the cooling behavior inside a spray tower for a typical flue gas are discussed. The heat and mass transfer is computed using computational fluid dynamics (CFD). The interaction between the discrete droplets and the average gas flow depending on the tower geometry is described for differ
