NEARLY FREE MOLECULAR FLOW. A COMPARISON OF THEORY AND EXPERIMENT

Abstract

Measured drag coefficients for cylinders, normal strips and spheres in nearly free-molecular flow at M = 6, 8 and 10 are correlated with a collision-rate parameter suggested by the modified Krook model, and compared with theoretical estimates based on a variety of kinetic models and methods of analysis. The comparison of theory and experiment and the comparative effectiveness of various rarefaction parameters are discussed, and suggestions for further experimentation are made.
