Co-Current vs. Counter-Current Spray in Gas Cooling Applications

A CFD-Based Performance Analysis 

Cooling hot gas is necessary in many industrial processes to protect equipment and ensure employee safety. Daniel deLesdernier, Advanced Spray Engineering Services Manager at BETE, presents a computational fluid dynamics (CFD)-based analysis of co-current and counter-current sprays, offering considerations for those seeking to improve evaporation efficiency and minimize duct length in their gas cooling applications.

What you’ll learn:

• How spray direction affects droplet evaporation and heat transfer rates.
• Performance differences between full cone and hollow cone nozzles.
• The effects of spray orientation on convection and diffusion processes.
• Key design considerations, including nozzle placement, pressure drop, and risk of clogging.
