Recreating hydrodynamic cavitation paper's results at larger scale
 

I am interested in creating hydrodynamic cavitation through a slit Venturi reactor. 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. How hard will modeling this caviation be to recreate? Will caviation still occur at the larger size and will the results in their conclusion still hold?

I am inexperienced with CFD but these are questions I need to find the answer to. I am trying to create a CAD model and recreate in simFlow but it is a bit advanced for me at the moment so I've come to the internet for guidance. Thanks for reading.
