Simulate water flow - Any "easy" program ?

post #1 of 14
Thread Starter 
Hi

Im starting on designing / drawing some waterblock, but really want to test how the flow is - If I make some changes, test if they are good / bad for the performance - Making myself clear ? redface.gif

Im using Autodesk Inventor to do my design, so is there any "easy" way to simulate the flow, without being an engineer ?

Regards Henrik

Don't go with Ansys unless you have an exceptional understanding of mathematics.
The easiest try would be with Floworks.

Oh wait, you were serious?

The problem you will face is that you are trying to model a turbulent stream with some accuracy. This is difficult at the best of times as even the choice of solver or the shape of your mesh will influence your results. Fluent is a good program for this, problem is the licence runs into the tens of thousands and you would need to know what you are doing.

If you want a quick and dirty estimation tool then look at something like Floworks as DirectOverkill suggested, however take any results with a large grain of salt. It would probably be as good a starting point as any for picking some designs to test.

Are you looking at flow rates / patterns or heat transfer rates or both?

either way you're going to have a fun time designing a block the balances low restriction and good thermal conductivity

engineers have a hard enough time doing it, half the time it comes down to dumb luck and lots of prototypes, where fractions of a millimeter can make a difference, that is if you want the best balance if you're just doing this for fun, it doesn't really matter all that much, since a decently designed block should perform good enough within a few degrees of top performing block with how efficient water cooling is

Our college has a couple licences, i think its around $30,000 MSRP, not sure what you're price range is.

Are you thinking on Cosmos FloWorks ?

Just what I want redface.gif - Right now I got 5 different design, and really want to see which one will be the best ground design to work more on.

Would love to see both smile.gif

Already having a ton of fun with it biggrin.gif

But damm all the programs just cost a fortune. (I know that Inventor also cost a fortune, but setting on a student licence)

Found this Autodesk Simulation CFD, but my school dont have any licens, dammit ...

Still looking, would love to play with it smile.gif -

Thanks redface.gif - Will see if I can get access to Solidworks and try it out ....

Would love not to mill 5-10 prototypes biggrin.gif

Searcing for threads with custom block, but noo one uses flow simulation ? - Do all just make the block and hope ?

This guy did some simulation, but looks could be done much much better once it goes out for sales (imo).
