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.

Experimental and Numerical Approaches for Improving Rolling Contact Fatigue of Bearing Steel Through Enhanced Compressive Residual Stress
Dr. Xiaomin Cheng, The Ohio State University, Doctorial Dissertation, 2007. A hard turning model was developed to evaluate the influence of machining parameters and tool edge geometry on the temperature distribution, cutting force and residual stress profile. Shot peening process was also investigated for its efficacy in imparting compressive sub-surface residual stress in hardened surfaces. Single and multiple shot models were also developed to study the effect of shot peening process parameters, workpiece material, surface conditions and the interaction between individual shots on the distribution of the compressive residual stress field.
