Bulk Viscosity of Dilute Gases and Their Mixtures

In this work, we use the Green–Kubo method to study bulk viscosity of various dilute gases and their mixtures. First, effects atomic mass on diatomic gas by estimating four different isotopes nitrogen gas. We then addition noble consider mixtures with three gases, viz., neon, argon, krypton at eight compositions between pure It is followed an estimation oxygen for compositions. case, composition are considered, 25% N2 + 75% O2, 50% 78% 22% O2. The last aimed represent dry air. A brief review works that incorporation in analysis flow situations has also been provided.
