 Dr. Marvin E. Goldstein
Specialty: Aeronautics/Unsteady Fluid Mechanics/Turbulence
Email | Phone: (216) 433-5825
Dr. Goldstein served as the Chief Scientist at the NASA Glenn Research Center from 1980 to 2004. His technical accomplishments include a long list of "firsts," including the development of an explanation for boundary layer receptivity to free stream disturbances, a rational analysis of oblique wave model interactions in shear layers, the theory for the so-called Klebanoff modes that are observed in boundary layers at high to moderate levels of free steam turbulence levels and an analytical solution for the problem of flutter in a cascade with strong in passage shock waves
 Robert C. Hendricks
Specialty: Seals/Fuels/Fluid Dynamics
Email | Phone: (216) 433-7505
Mr. Hendricks successful operation of the liquid oxygen (LOX) ammonia manned rated rocket engine turned to providing critical heat transfer design data for fluid hydrogen, now used in all LOX-hydrogen engines including the Space Shuttle Main Engine (SSME) and crew and cargo vehicle (J2 X,S) engines. For this work he received the NASA Medal for Exceptional Scientific Research. Work with cryogens hydrogen and oxygen led to the development of widely used thermo physical property codes GASP and WASP. Throughout the period, this work provided fundamental understanding to boiling, two-phase flows, supercritical and near-critical fluid behavior.
