论文摘要
我们分析了Navier Stokes方程，并表明所有非粘性，无旋转的流都是正压。据我们所知，这在文献中从未在文献中说过，并且间接地表明，使这些流动非偏见需要涡度。压力，温度，速度，熵，焓和Bernoulli函数都被推导为密度的函数（这是空间和时间的函数）。当我们还需要稳定的流动时，伯努利函数在所有空间中都是一个常数，而不仅仅是在流线上。
We analyze the Navier Stokes equation, and show that all non-viscous, irrotational flows are barotropic. As far as we know, this has never been stated in the literature before, and indirectly suggests that vorticity is required to make these flows non-barotropic. Both the pressure, temperature, speed, entropy, enthalpy, and a Bernoulli function are derived to be only functions of the density (which is a function of space and time). When we also require steady flow, the Bernoulli function is a constant in all space, not just on streamlines.
