I am glad to see the animosity dissipate...
I have to confess, to BillA's remark, that this thread is somewhat representative of the process through which I am going, to develop this block. It is chaotic, approaches many aspects at either the same time, or in no particular order. As with software development, 80% is planning, 20% is coding (under the best circumstances). Since this is a part time effort on my part, I will certainly not make any scientific claims of any kind of breakthrough. As myv65 pointed out, I'm trying to use "the best of the best".
In this particular design, the aim is to optimize the flow where it is needed, and I believe that it is achieved with the "tube-in-tube" approach, combined with the radial pattern. As Cathar pointed out, the optimal copper to channel ratio he found to be ("between 1.5 and 0.8") is entirely applied here, where the ratio will vary between 1.5 and 0.75 . My numbers may turn out to be slightly different, but I won't know this until I've completed my calculations.
In the mean time, I view this thread as having what I call a "hack-and-slash" approach (a D&D expression refering to a simplistic "kill everything" campaign). There are many parts here, and some more in the e-mail exchanges between Utabintarbo and myself. Utabintarbo has made significant contributions (Thanks Bob!). All in all, I can see that there isn't a clearly defined approach to this, but most of the design has been inspired from an idea of mine, and from some of Cathar's results. That's where it all comes from, the rest is merely the details of an idea.
If this was an ordered development, the first thing for me to do would have been to recruit a specific number of people, so that we can list the parameters, define an approach, set up a schedule, and since this would become a collaborative effort, assign each member a task (except for non-participating team members). Then, and only then could I claim any kind of pseudo-scientific approach (Now tell me honestly BillA, would you have responded positively to such an invitation?)
To point the obvious:
this is a ProCooling forum, not NASA.
This entire effort is revealing of the many constraints a block designer faces, the most important of which is the construction. I have dreamed up many other blocks which were unfortunately impossible (or too expensive) to make.
Back to work.
At this point, I think that we should send Fixittt some kind of drawing, even if it's preliminary, because I have many unanswered questions in that area, and Fixittt doesn't appear willing to budge without one!
