Abstract

The relative density distribution in the rarefied CO2 flow field behind a perforated plate has been experimentally investigated on the range of Knudsen numbers 10−3 ≤ Kn ≤ 10−1. The results of these experiments serve to demonstrate the validity of using the molecular velocity distribution function for determining the relative density on the Knudsen number interval in question. This distribution function was previously employed for calculating the parameters in molecular beams formed by capillary sieves in the free-molecular flow regime [1].
