aww man..you guys totally kill me. so with hi-flow blocks like the swiftech..there WILL be marked improvement with hi-flow rates? :shrug:

pH, which is why with two radiators, you can run at 2gpm through the waterblock and only 1 gpm through the rads, which is better for both

for (much) more on turbulence try here and here

and for numerical modeling (CFD anaylsis), starting here

OK this is much more information than I can absorb in one sitting. I am not an engineer, so the terminology and vocabulary is ggonna take a bit of brushing up on (I have had a few environmental engineering courses that discussed Re and laminar vs turbulent but it was long ago). I will try and get at least fluent in the terms and relevant equations tonight; I probably will have more questions than answers though.

It seems that some thoughts on the matter have reversed though. A while back I read that the only type of block with hope of truly turbulent flow was the die impingement design. This made sense to me as it seemed counterintuitive that chaotic mixing would go on in a block that made water progress orderly through channels. Perhaps you could decrease the boundary layer a good bit with more water velocity but I assumed that it still would be an impediment to heat transfer.

However, the gist of at least some of those threads was that moderate flow rates are sufficient to move to turbulent flow patterns in channel type blocks. This doesn't make sense to me. My frame of reference with Re is colloid science (flocculation kinetics) not waterblock design so perhaps I am missing something simple...

i'm TOTALLY lost in what two of you are saying already..

Now I am sure of it

Welcome back Bill

ph, is that really english?

ablaze · 04-01-2002, 02:18 PM

hey guys I was thinking. with the power in the 1060, wouldn't there be a significant increase in the risk of leaks? I mean I'm gonna use hose clamps everywhere there's a connection but still..yknow..kinda dangerous?

4.5psi max
it has volume, not (real) pressure capability

so it doesn't put more stress on the tubes?
