Navier-Stokes equationself-adjoint operatorbilinear transformationCauchy problemHilbert spaceSobolev classIn the space of functions with values in Hilbert space, we consider the Cauchy problem u′ t + Au + B ( u, u ) = f ( t ), u (0) = 0, 0 ≤ t ≤ T . We construct examples of ...
而对于淀粉糊，糖浆这样的非牛顿流体来说，整个navier-stokes方程都用不了，因为它的受力和变形之间没有线性关系，这时对于受力连续变换的情形，根据Cauchy定理退回tensor analysis还是能处理的，如果出现冲击波情况会更复杂。非牛顿流体也不是万能的，如果剪切力超出其承受限度一样会被敲碎，这在理论上能解释液体防弹衣...

One of the obvious examples is sound. Description of such phenomena requires more general presentation of the Navier–Stokes equation that takes into account fluid compressibility. If viscosity is assumed a constant, one additional term appears, as shown here:...

滥觞先来总结一下Navier-Stokes方程的解适定性问题研究的历史。 此方程适定性研究之滥觞,应是Lerry的 [1]这篇法文文献。这篇文献很长有英文的翻译版本。这篇文章告诉我们有限能量的初值(L^2)存在至少一个全局弱…
