Using theoretical analysis and numerical calculation method, the axial adiabatic compression of a spinning non-ideal gas in a cylinder with a smooth surface is investigated. We show that the axial pressure of a spinning gas will gradually become lower than that of a stationary gas during continuous compression, even though the initial axial pressure of the spinning gas is larger than that of the stationary gas at the same initial temperature and average density. This phenomenon indicates that the axial compressibility of gas is improved in a rotating system. In addition, the effect of different forms of virial coefficient B(T) on pressure and temperature changes in spinning and stationary gases are investigated. Research on the axial compressibility of spinning non-ideal gas can provide useful references for fields that require high compression of gases, such as laser fusion, laboratory astrophysics, and Z-pinch experiments.

改善纺丝非理想气体的轴向可压缩性的研究

利用理论分析和数值计算方法，研究了具有光滑表面的圆柱体中旋转的非理想气体的轴向绝热压缩。我们表明，即使在相同的初始温度和平均密度下，旋转气体的初始轴向压力大于固定气体的轴向压力，连续压缩过程中旋转气体的轴向压力也会逐渐低于固定气体的轴向压力。 。该现象表明在旋转系统中气体的轴向可压缩性得到改善。此外，不同形式的病毒系数B（T）研究了纺丝和固定气体中压力和温度的变化。对纺丝非理想气体的轴向可压缩性的研究可以为需要高度压缩气体的领域提供有用的参考，例如激光聚变，实验室天体物理学和Z捏实验。
