Storm/G7 Prototype + Piccies - Page 7

Stew or indeed anyone ever seen this paper?

Measurements of heat transfer coefficients between turbulent liquid jets and radially finned heat disks place at the bottom of an open vertical circular cavity

(no science explanation: really fast water jets into a g series style cavity with fins radial the bottom)
4 docs, TJ Heindel as main author but more interestingly the final doc (although he’s a prof) is FP Incropera (wrote one of the top starter textbooks on heat transfer there is and has been doing jet impingement heat transfer for 25 years). Show fins at the bottom increase heat transfer by a factor of 3 - 5. Not a clue about how to use them in a small scale like a g series but for larger scale single nozzle 2.5 CNC machines could be quite useful. I like the way its all non dimensional.

Interesting factoid from the above paper.

Some Japanese blokes apparently did some work on an array of confined jets aka a G seris style design for cooling of supercomputers in 1985!

Ah swings and roundabouts, and just goes to show that everything has been done before.

I am simply loving the potential of this new block. I feel like if you're going to spend $300+ on a black, it might as well last you a long long long time. I assume it's going to come with all the Cathar accessories you're known for, in addition to being semi future-proof?

I want to have my kids using this block later in life

Look at the dates of the post before yours Seven. Almost a year old.

Cathar · 09-24-2006, 09:41 AM

Just to be clear, the G7 block is not forgotten. It's just under-going a hiatus while I get some things sorted out at my end. It has been a while between updates, but I've been posting a bit about what's going on at some of the other forums.

Oh, I'm very sorry about this thread ressurection. I saw Cathar's signature over at OCForums and I immediately began the search for this.

I am always interested in any discussions Cathar cares to join. Looking forward to seeing some more of your excellent work. Hope you are healing up well.

It isn't a problem. Just wasn't sure you realized how old the thread is. Maybe Cathar is planning a new top for the Mounting to the AM2 mobo's.

I picked up some hypodermic SS tubing, for an experiment with this design.

I won't have time for it this year, as I'm still assembling my testbench, but definitely next year.
