Hi,
first i made this block:
with this base:
its inlet barb narrows down from 10mm to 7mm ID to speed up flow for "impingment".
Butt didn't perform any better than with a plain old 10mm ID fitting though.
Any ideas for improvement? I made this base yesterday with thinner copper and smaller drill holes:
and thought maybe a grill after the inlet barb with 9 holes drilled like this

Have you had success with anything like this or anything else or am i barking up the wrong tree?
