Hi Omid

It looks like orgtbl-to-latex is calling org-export-string-as on each table
cell, which is presumably what is wrapping each \mu inside $$.   This seems
wrong-headed to me, but I can't say I really understand what the code is
trying to achieve.

A workaround would be to directly use orgtbl-to-generic instead. Just
replace your ORGTBL line with

#+ORGTBL: SEND Ah-advection orgtbl-to-generic :splice t :skip 0 :lend "
\\\\" :sep " & "

Will
