计算流体力学的出路

hawlin

现在做计算流体力学在哪方面会更有出路。。。。可压缩还是不可压缩。。还是。。。。

各有各的出路，毕竟这个世界上大部分问题不像数学中的1+1=2那样明确，且斩钉截铁。主要是看你的兴趣即可。其实都一样，建议可压缩和不可压缩都看看，看看兴趣是哪个？

都玩精通不就没有问题了么~

应该说都有出路，关键看你自己的机遇如何。

也不能这么说。看解决什么问题。如果一个问题用现有软件能解决（当然是考虑了经济性，可靠性，精确性等因素的），那当然就用现有的就行了。相反，如果一个问题用现有的东西解决不了，那就得创造出新东西来解决，当然这个创造的方式就是发展处新理论，新技术，手段可以是编程，可以是实验等等。所以关键看你想解决的问题属于上面说的哪一类？

My understanding of this problem is the following. CFD is both cursed and blessed because: (1) The mathematical problem associated with the Navier-Stokes equations is nowhere near to be solved so there are things to be done; and (2) advance in computer hardware, software, and human experience allow CFD as a useful tool so there are things can be done.

CFD is related to many fields in science: mathematics, applied mathematics, and physics. One thus can pick any sub-field(s) according his/her own interest and inclination. A larger and more relevant question should be: why should someone study hard-core science at all? Why not business and such not?

One particular field which will be active for years to come is "complex and active fluids"....

complex and active fluids是什么？求详解

luo@odu.edu

Complex fluids usually and loosely mean non-Newtonian fluids and more. Polymeric fluid is a good example. One key characteristics of complex fluids is that the Navier-Stokes equations as well as the stress-strain constitutive relation (which is valid for simple fluids) are no long applicable.

Active fluids means fluids with living/active organisms, such as blood flow or fluids with bacteria.

有许多文章关于模拟弹性边界，请问哪种更实用

软件玩好了也不容易。
