Nanofluid tested with three different temperatures on a Q6600

[relttem]

The only thing I can really point at in terms of cons to nanofluid was the tube staining and residue that was left behind in the reservoir. To me this happened at an accelerated pace with nanofluid compared to any other coolant I've used, was also much more difficult to clean than other coolant residue/staining.

However, I made relttem aware of this problem shortly after the first test and he stated they would look into any possible resolutions for the problem.

That was a surfactant problem, which we are working on now. The surfactant, for those that don't know, is going to keep the nanoparticles separated in the fluid. If they agglomerate, which I have mentioned earlier as a problem, you have what is called "stokes settling", and this gets worse as more agglomeration occurs. The rate of agglomeration occurring is going to be a function of the available surface area. So, basically, the surface area doubles when two particles stick together and increases as more stick..that gives more mass, which is going to cause the particles to settle faster. But, we are definitely working on that because that, to us, is the most important thing.
