Modeling of Water and Lubricant Sprays

Dr. Chun Liu, The Ohio State University, FIERF Forging Fellow Doctorial Dissertation, 2007. Modeling of water and lubricant sprays has significant impact on the performance of spraying systems, die life and the proper forming of the part. This research is concerned with developing a more complete understanding of spray cooling effects in hot forging process by modeling the temperature of tool, modeling of droplet spread and evaporation on the tool surface, modeling of average cooling rate and film formation in lubricant sprays, and process design to achieve desired cooling rate.
