各位大佬,在wilcox turbulence modeling for CFD 教材中,chapter 2.4 ,page -41中,如图所示,红框部分小弟理解不上去,请问书中这一步红线部分是从哪里来的,下标ki,k 和 i,kk代表什么,小弟没有理解上去,有没有大佬可以指点一二,浪费大家时间了,不胜感激。
第一个下标表示分量,第二个下标表示导数。 \begin{equation}\notag s_{12,1}=\frac{\p s_{12}}{\p x}=u_{2,11}=\frac{\p}{\p x}\left(\frac{\p u_2}{\p x}\right) \end{equation}
@李东岳 感谢李老师的回复,一下子就通透了
