Abstract

Numerical and experimental results for a rarefied gas expansion through a thin circular orifice are presented. The orifice flow was used as a calibration test for a torsional thrust stand designed to measure force levels of 10^-6 to 10^-3 N. Molecular nitrogen is used as a test gas. The mass flux and thrust measurements are compared with direct simulation Monte Carlo results for Knudsen numbers from 40 to 0.01 and plenum to facility background pressure ratio 10³ - 10⁷. Different factors that affect the total propulsive force such as jet backflow and facility background gas penetrating the jet are analyzed. The measured and calculated mass flux and total propulsive force agree well for Knudsen numbers less than 1.
