Research

Penner collaborated with

in the later years of von Kármán life for 15 years. The Kármán–Penner flux fraction, first introduced by Von Kármán and Penner in 1954, is the fraction of mass flux of a particular chemical species (it is used sometimes in place of species mass fraction). He has received numerous professional honors, including election to the National Academy of Engineering, the American Academy of Arts and Sciences, the International Academy of Astronautics; he has also been awarded the Distinguished Associate Award from the US Department of Energy and the Founders Award from the National Academy of Engineering. Penner also founded two scientific journals: the Journal of Quantitative Spectroscopy and Radiative Transfer in 1960, serving as chief editor for over 30 years and in 1975 he founded Energy, An International Journal and of the (classified) Journal of Defense Research.

Publications

Penner has published around 320 journals in his lifetime and authored many books and monographs.
