Would Electrical Engineering be a better home for this question, e.g. because of obvious analogue between hydrodynamics and electronic circuits?

Comment to the question (v1): Consider adding more references in order to receive useful and focused answers.

comment Confusion with anti-symmetric tensors!
Comment to the question (v4): There is in general no reason why the anticommutator $\{A,B\}_+$ of two $n\times n$ matrices $A$ and $B$ should only have a trace-part $\frac{2}{n}{\rm tr}(AB)~{\bf 1}_{n\times n}$ and no traceless symmetric part. (There is a corresponding representation-theoretic formulation in terms of fusion rules.)
