Dr. Cheng Xu is an American aerodynamic design engineer and engineering manager. He is a Fellow of American Society of Mechanical Engineers and a member of 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 pioneer 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 turbomachinery. He 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 developing 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]

Biography[edit]

Xu attended the Nanjing University of Aeronautics and Astronautics and received an MS in aerodynamics in 1992. He received a PhD in mechanical and production engineering from the Nanyang Technological University, Singapore, in 1997 and a PhD in turbomachinery from the University of Wisconsin, Milwaukee, in 2000.
