That plan was something I threw into paint in only a few minutes, block volume and in fact all design specifics were secondary. Mostly I was interested in a star shape of fins directly above the core to increase surface area and direct water flow. Fins could feature radius corners where they meet the base. This design would eliminate jet dead spots due to it splitting the flow into multiple parts, i.e. the core of the star would be where the dead spot would normally form. This star shape I think would lend itself better to a circular interior anyways, with dual opposing outlets from the main chamber channeled into a single outlet barb.

What I see lacking in current commercial block design is sufficient, effective surface area and I think this design would address this in a direct impingement style block. The downfall (aside from unproven results) is machining complexity, and might even prove more economical to cast if it reached volume production.

BTW cylindrical smooth bores like the interior of a bard fitting are considered nozzles, at least in the fire service. Go to your local station and have a look at a deck gun on top the engine to get an idea of what I mean. Of course that doesn’t mean your average garden/hobby pump will be able to generate enough pressure and volume to produce the desired stream.

I’ll be watching morphling’s work since he’s been developing a similar concept.
