Mark A. Kedzierski (Fed)

Dr. Mark A. Kedzierski is a mechanical engineer in the HVAC&R Equipment Performance Group of the Energy and Environment Division (EED) of the Engineering Laboratory (EL) at the National Institute of Standards and Technology (NIST). Dr. Kedzierski received his Ph.D. in Mechanical Engineering from The Pennsylvania State University in 1987. In that same year, he joined the Thermal Machinery Group (now the HVAC&R Equipment Performance Group) as a Mechanical Engineer at the National Bureau of Standards. Since then he has investigated two-phase heat transfer of alternative and multi-component refrigerants with and without oil both on a fundamental basis. Dr. Kedzierski is applying a fundamental metric that resulted from the refrigerant/lubricant work to one for water quality. He also investigates micro-heat transfer as it relates to Micro Electro Mechanical Systems (MEMS) and nanolubricants to improve refrigerant boiling heat transfer. Dr. Kedzierski has taught several professional short courses on heat transfer enhancement and alternative refrigerants and heat transfer measurements. He also works closely with DuPont, Trane, Wolverine, UOP, ICI, and other companies to ensure that his research is of value to these U.S. Industries.

Dr. Kedzierski was recognized with the William P. Slichter award for his contribution to building and strengthening ties between NIST and Industry. Dr. Kedzierski has also received the Bronze Medal award from the Department of Commerce for improving the mechanistic understanding of heat-transfer-enhancing additives and refrigerant/lubricant mixtures.  He has received four "best paper" awards. Dr. Kedzierski is a co-author of "Condensation" Chapter 15 in Handbook of Heat Transfer, John Wiley & Sons and has received several best paper awards.

Dr. Kedzierski is a fellow of the American Society of Mechanical Engineers and the past chairman of that organization's K-10 heat Transfer Equipment Committee, and past chairman of the Government Relations committee and an award committee. He is vice-chair of ASHRAE's SSPC 41 and a member of SPC 41.4.
