Dr. Cheng Xu is a Chinese American aerodynamic design engineer and engineering manager. He is a Fellow of the American Society of Mechanical Engineers and a member of the Technical Committee on Energy and Power Systems, IASTED.[1] He also served as a guest editor of International Journal of Rotating Machinery.[2]

Dr. Xu has made important contributions to the three-dimensional aerodynamic design and turbomachinery research. He is one of the foremost pioneers of the three-dimensional centrifugal compressor impeller, diffuser design, axial compressor blade design, turbine blade, turbine endwall optimization with efficiency and cooling effectiveness, and gas turbine LPT and nozzle optimization in the field of turbomachinery. He has performed advanced aerodynamic research and applied his research results to industry turbomachinery design. He developed a three-dimensional viscous optimization design procedure for industry turbomachinery aerodynamic and heat transfer design. He was one of the pioneers that helped develop high efficiency and wide operating range centrifugal compressor and axial compressor compressors. He has published many papers in peer-reviewed academic journals and refereed conferences. In 2006, Dr. Xu was awarded the 2006 Best Paper Award from ASME for his paper A study of Single Stage Centrifugal Compressor.[3] His papers are also cited widely by many researchers.[4]

Biography[edit]

Xu was born in Anhui Province, China in 1964.

Dr. Xu attended the Nanjing University of Aeronautics and Astronautics and received an MS in aerodynamics in 1992. That same year, he became an assistant professor at the same college. In 1994, he went to Singapore where he proceeded to receive a PhD in Mechanical and Production Engineering from the Nanyang Technological University. He moved to Milwaukee, Wisconsin in 1998 where he studied for a PhD in turbomachinery from the University of Wisconsin, Milwaukee.

After he graduated in 2000, he began work as an Aerodynamic Development Engineer for General Electric Energy in Schenectady, New York. In 2004, he moved to North Carolina to work as a Mechanical Engineering Manager for Ingersoll-Rand in Cornelius, NC, where he worked to make many of his advances and discoveries in the field of turbomachinery. In 2007, he was hired as a Senior Engineer at Honeywell in Torrance, California. In 2012, he was hired to work for General Electric in Mason, Ohio. Today, he works as a Mechanical Engineer for FS-Elliott in Murrysville, PA.
