A disk spindown experiment allows measurement of tangential momentum accommodation coefficients of different gases and material combinations in a consistent manner. Aluminum is tested for a range of gases, including monoatomic, diatomic, and triatomic gases. The results confirm previous experimental results that show a reduction in tangential momentum accommodation coefficients with increasing molecular masses of gases. In addition, the results reveal a previously unreported phenomenon: that the tangential momentum accommodation coefficient is also a function of the molecular structure of gases.
