Joseph Prahl, a longtime Case Western Reserve faculty member—and a payload specialist for the 1992 Columbia space shuttle flight—will be remembered Thursday in a memorial service on campus at Amasa Stone Chapel.
Prahl, 75, a professor and researcher with great expertise in dynamics, fluid mechanics and thermodynamics, died April 19 at his home in Cleveland. (...)
1992 space shuttle experiments and more
Perhaps Prahl’s most recognized work was for the United States space program.
His association with Cleveland’s NASA Glenn Research Center began in 1970; he took a leave of absence from the university from 1990 to 92 to work as a payload specialist at NASA Marshall Space Flight Center in Huntsville, Alabama.
That included the 13-day Columbia mission in June 1992, when Prahl helped with more than a dozen experiments in areas such as crystal growth, fluid physics, combustion, bioprocessing, space-acceleration measurement and the effects of extended duration orbit on the human body.
He also assisted in experiments in combustion, surface tension, droplet dynamics and crystal growth. His background in surface-tension-driven flows and combustion played a role in his selection by NASA as a payload specialist for the mission.
His NASA work wasn’t limited to Columbia.
He also worked with support from NASA Glenn Research Center on studies in tribology and oil-free turbomachinery; in the chemical kinetics of hydrogen-oxygen and propane-air systems; and in the use of mechanical seals for turbomachinery and space craft docking systems. (...)
