This is a bit of a conundrum, if you ask me. The compound noun in my title, 'Fluid Flow' does not require hyphenation. On the other hand, this is then followed by '-Related'. If I were to put: "Fluid Flow-Related..." then it would look like 'related' only relates to the second noun, i.e. 'fluid'. So I am inclined to put "Fluid-Flow-Related..." Yet this arguably looks a little odd, and over-fussy - especially in a title.
If anyone can shed any light on this head-scratcher, I would be most grateful!
(NB: regarding the link to a possible duplicate thread - the solution which I am specifically seeking to avoid [in the question I have put forward] is the very solution which is suggested in the other thread; in effect I am actually asking how to avoid a two-hyphen solution.)
