EXPERIENCE

Dr. Wisler’s distinguished career at GE Aviation spanned 38-years.He is a member of the US National Academy of Engineering and was inducted into the GE Aviation Propulsion Hall of Fame in recognition of his lasting and widespread impact on the aviation industry and GE’s business.He is recognized as an international expert in turbomachinery aerodynamics technology.

 During his tenure at GE, he held positions of increasing responsibility for conducting and managing advanced technology programs as Manager, Aerodynamics Research Laboratories and University programs. His work to improve airfoil shapes and understand the complex flow fields in the rotating components of gas turbine engines has been instrumental in reducing loses (reducing fuel burn) and improving performance. His research is on the leading edge of technology and has won several prestigious international awards for best technical papers of the year.

During the decade before retirement, he created and managed GE’s University Strategic Alliance (USA) Program, which developed long-term, teaming relationships with key universities to concentrate academic expertise on solving issues of fundamental importance to GE’s business needs.  In this capacity, he was responsible for implementing and coordinating programs in the areas of gas turbine propulsion, turbine heat transfer, aeromechanics, acoustics, compressor technology, probabilistic preliminary design, materials, combustion, tribology, error proofing in design and manufacturing, and computational fluid dynamics. He was also responsible for managing in-house research programs in a broad range of technical disciplines relevant to GE’s needs.

Immediately after retirement from GE, Dr. Wisler joined MIT’s CDIO Initiative to revitalize engineering education worldwide. The goal of CDIO is to produce engineers who are “ready to engineer” at graduation. There are currently over 90 universities participating in the CDIO Initiative.

Dr. Wisler is a Fellow of the American Society of Mechanical Engineers (ASME), the Editor of the ASME Journal of Turbomachinery and an Associate Fellow of the AIAA. He is a past ASME Sr. Vice President and Past Chair of the Board of Directors of the International Gas Turbine Institute (IGTI) of the ASME. He is an honorary member of the Japanese Gas Turbine Society.

Dr. Wisler’s active participation in teaching spans 38 years. He taught graduate level courses in aerodynamics and compressor design in GE’s Masters and Ph.D. program in association with The University of Cincinnati and The Ohio State University. He holds adjunct professorships at The Ohio State University and the prestigious Tsinghua University in Beijing.

TECHNICAL PUBLICATIONS

Dr. Wisler has written 41 technical papers and one book chapter and has given five plenary lectures at international conferences and gatherings. They will be supplied upon request. 

His six most important technical papers, along with a summary statement of relevance, are:

1. Wisler, D. C. And Mossey, P. W., “Gas Velocity Measurements Within a Compressor Rotor Passage Using the Laser Doppler Velocimeter”, ASME, J. of Engineering for Power, April 1973, pp. 91-96.

Relevance: This paper is pioneering. It reports the first application of laser velocimetry to measure gas velocities inside the rotating blade row passages of axial-flow compressors. Such measurements are commonplace today.

1. Wisler, D. C., Bauer, R. C. and Okiishi, T. H., “Secondary Flow, Turbulent Diffusion and Mixing in Axial-Flow Compressors, ASME Journal of Turbomachinery, Oct. 1987, Vol. 109, pp.455-482. Won the 1989 ASME Melville Medal

Relevance: This paper decisively and exquisitely resolved a major international controversy by determining the correct fluid mechanics phenomena that produce radial mixing of the fluid in axial flow compressors

1. Leylek, J. H. and Wisler, D. C., “Mixing in Axial-Flow Compressors: Conclusions Drawn from Three-Dimensional Navier-Stokes Analyses and Experiments”, ASME J. Of Turbomachinery, Apr. 1991, Vol. 113, pp. 139-160. Won the 1990 IGTI Gas Turbine Award

Relevance: This paper is presents a computational fluid dynamics (CFD) solution for the mixing controversy described in the above paper and shows from CFD analyses that both secondary flow and turbulent diffusion are responsible for mixing in axial flow compressors.

1. Manwaring, S. R. and Wisler, D. C., “Unsteady Aerodynamics and Gust Response in Compressors and Turbines”, ASME J. Of Turbomachinery, Oct. 1993, Vol. 115, pp. 724-740. Won the 1992 IGTI Gas Turbine Award

Relevance: Turbomachinery blade rowsare subject to periodic unsteady flow (gusts) generated by airfoil wakes. These gusts can produce significant unsteady forces, which if severe, can cause blade failure. This paper presents gust response measurements and analyses for multistage compressors and turbines, showing for the first time a detailed comparison with design/analysis methods and the importance of properly accounting for both vortical and potential disturbances in blading design.

1. Halstead, D. E., Wisler, D. C., Okiishi, T. H., Walker, G. J., Hodson, H. P., Shin, H-W, “Boundary Layer Development in Axial Compressors and Turbines” Part 1 of 4: Composite Picture, ” J. of Turbomachinery, January 1997, Vol. 119, pp.114-127, Part 2 of 4: Computations and analysis, J. of Turbomachinery, January 1997, Vol. 119, pp.426-444, Part 3 of 4: LP Turbines, J. of Turbomachinery, January 1997, Vol. 119, pp.225-237, Part 4 of 4: Compressors, J. of Turbomachinery, January 1997, Vol. 119, pp.128-139. Won the 1998 ASME Melville Medal

Relevance: This paper presents the first time-resolved measurements and analyses that show how unsteady boundary layers develop on the surfaces of the blading in multistage compressors and turbines.  It clearly shows the important effects of wake passing in creating a calmed region, which is effective in suppressing flow separation and delaying the onset of transition on the blading. Such a phenomenon is not accounted for in design and analysis procedures that assume steady flow.

1. Storace, A. F., Wisler, D. C., Shin, H-W, Beacher, B. F., Ehrich, F. F., Spakovszky, Z. S., Martinez-Sanchez, M., Song, S. J., “Unsteady Flow and Whirl-Inducing Forces in Axial-Flow Compressors. Part I – Experiment.” Journal of Turbomachinery, July 2001, Vol. 123, pp. 433-445, Part II – Analysis.” Journal of Turbomachinery, July 2001, Vol. 123, pp. 446-452. Won the IGTI 2000 Best Paper Award for both the Turbomachinery Committee and the Structures and Dynamics Committee and Won the 2003 ASME Melville Medal

 Relevance: This paper decisively resolves the nature of the potentially destructive reaction forces developed by an axial compressor stage due to lateral displacement of the rotor shaft. This is an issue of long-standing and very significant importance in designing and analyzing the rotordynamic stability of axial compressors.
