Four NASA Lewis Research Center Engineers to Receive Distinguished Publication Award

Cleveland, OH -- The 1992 Lewis Distinguished Publication Award recipients were recently announced by NASA Lewis Research Center Chief Scientist Marvin E. Goldstein. The four Lewis engineers, co-writers of the publication, will receive certificates and share a monetary award in an upcoming awards ceremony at the Lewis center.

The Distinguished Publication, "Experimental and Computational Investigation of the NASA Low-Speed Centrifugal Compressor Flow Field," discusses the combined research of laser-based measurement systems with a computational model to gain understanding of the airflow in centrifugal compressors.

The results, reported in their paper, have significantly enhanced the understanding of the airflow in centrifugal compressors along with serving as a benchmark to check the accuracy of new computer programs that will be used to design improved compressors for more efficient aircraft engines.

Centrifugal compressors are widely used in small jet engines that power helicopters, small executive aircraft, cruise missiles and in automobile turbochargers. Historically, the airflow inside centrifugal compressors has been difficult to determine. This has limited the performance improvements of centrifugal compressors that in turn has impacted the performance and efficiency of small jet engines.

The Distinguished Publication Award is presented by Lewis' Chief Scientist to encourage and reward outstanding research and technology contributions by staff members. A total of eight publications were submitted for this award.

Dr. Randall M. Chriss, an aerospace engineer in the Turbomachinery Flow Physics Branch, is currently conducting research in axial and centrifugal compressors using laser Doppler anemometry. A native of Toledo, Ohio, Chriss attended the University of Toledo where he received his bachelor's, master's and doctorate degrees in mechanical engineering. He has written eight other publications in the fields of jet engine compressor aerodynamics and supersonic aerodynamics. Chriss and his wife, Dr. Beth Llewellyn, reside in Cleveland Heights, Ohio.

Dr. Michael D. Hathaway, an aerospace engineer with the U.S. Army Research Laboratory, is currently conducting detailed experiments to investigate the fundamental flow physics of axial and centrifugal flow compressors. Hathaway earned his bachelor of science degree in mechanical engineering from the University of Washington and received his master of science and doctorate degrees in mechanical engineering from Iowa State University. He has written 16 other publications related to experimental and computational investigations of axial and centrifugal compressor flow physics. Hathaway, his wife Barbara, and their two children reside in North Ridgeville, Ohio.

Dr. Anthony J. Strazisar, a senior scientist in the Internal Fluid Mechanics Division, currently leads a team of four research engineers in conducting experiments on aircraft engine turbines and compressors in order to improve the understanding of flow behavior. He received his bachelor of science, master of science and doctorate degrees in mechanical engineering from Case Western Reserve University, Ohio. He has written over 20 technical papers on advanced measurement techniques in aircraft engine compressors. Strazisar, his wife Kate, and their three children reside in Chesterland, Ohio.

Jerry R. Wood, deputy branch chief in the Turbomachinery Flow Physics Branch, currently investigates flow physics in fan and compressor components of gas turbine engines using sophisticated computer programs. He received his bachelor of science degree in mechanical engineering from the University of Houston and his master of science degree in mechanical engineering from the Massachusetts Institute of Technology. He has written 16 other publications in the field of compressor design and analysis. Wood, his wife Carol, and their two sons reside in North Olmsted, Ohio.
