Invisible ls3 head demo

Don't forget a high speed/high resolution camera to be able to properly slow-mo the playback.
Icing on the cake would be, instead of a flowbench, a transparant cylinder and an actual highspeed moving piston which could vary speed with functional intake and exhaust valves, pumping those styroballs around.

An honest question, what are we supposed to learn from all that? Watching styrofoam balls fly around?

Now I know what will happen when I crash my corvette into a pillow factory.

yes good one !

Here is a good in cylinder camera of a running 4 cycle engine.

About the same-thing you would learn watching a CFD simulation except it's not a simulation.

[digger]

Actually it is a simulation but you can't see the airflow or velocity profile or gradients like on cfd

[BigBlockMopar]

Sometimes things only get 'seen', noticed/learned/explained until you actually see it happening.
And it never hurst to double check a simulation for correctness.
Just like Jon Kaase putting his finger in an intake port to get a 'feel' for what was actually happening inside.

Nope, there are no pressure waves present during the clear flow bench test, just continuous flow.

[Carnut1]

I agree Warp. Think of it as a snapshot of time in the port at lower than operating pressures.

At least those Lucas Oil Stabilizer displays at the autoparts store show how to increase windage. You know those gear to gear displays.

Based on the CFD image what would you guys change on this head to improve it?

I'd change the chamber to get rid of those sharp corners and eliminate that dead space. lol

It's from the bottom of this page with a couple of others talking about a virtual flowbench.

Kind of tough to make recommendations to the port based on 1 view angle.
