Prove hydrodynamic cavitation will occur

maco144 · September 11, 2017, 11:11

I am interested in creating hydrodynamic cavitation through a slit Venturi reactor. This is for the purpose of homebrewing as cavitation effect is desirable for certain steps in the brew day.

I have found this paper that models the CFD of circular and slit Venturis here: http://www.krishisanskriti.org/vol_i...0150106017.pdf

The conclusion is "Slit Venturi with slit of dimension 2mm height 3.14 mm depth operating at 8 atm gauge inlet pressure, slit height to length ratio of 1:1 and divergence angle of 5.5 degree are the optimized parameters for maximum cavitational activity."

I'm wondering if these results scale up as I need a slit dimension of 2 cm not mm. If someone wants to model and prove that caviation will still occur at the larger size and their optimized parameters will still hold consistent it is something I'd be willing to pay for. The main question needed to be answered is that indeed the cavitation effect will occur with a larger slit opening (or what is the maximum size slit that can create cavitation?). Thanks for the consideration.

Hi, I had experience exactly in area you describe. Cavitation device for oil heavy fraction refinery was developed and then, similar cavitation device for beverage production was also developed with the help of CFD and cavitation analysis.

Taka a look at pg. 9 in my portfolio.
