Theory for boundary layer reduction with motor driven impeller
 

Howdy everyone,

I was lying on the beach the other day while on holidays dreaming of water block design (doesn't everyone spend their spare time dreaming about wb design?)

anyway, has anyone tried a motor driven impeller inside the water jacket hard up against the block to distrupt/reduce the boundary layer?


Seals for the motor shaft would be easy for all those thinking about water leaking, i'm imagining a pair of double lipped shaft seals on a 10mm od shaft. I'm going to try the with a delrin impeller.


Worth a try, can see one benifit being very small pressure drop if it works.

Surely worth a try. I'm not sure if you can get more disruption than a storm block for instance, because if I get it correctly jet blocks were designed to do that.

If you decide to build one, give us the results please. Oh yeah ... and pics!!!

This idea will reappear until someone proves it's no good - see here.

EDIT: What I love about this approach is that it best answers the principle that all turbulence should be useful turbulence.
