Laminar flow - GIFs

That laminar flow concept applies to a large number of situations. I'm sure Jerry Branch of Branch Flowmetrics [spearhead of dynamic porting to intake and exhaust ports of performance engines] had a sixth sense in relation to making fuel-air mixtures run without wetting the surfaces. A great rabbit hole for those interested, a guy, self taught btw, who created an entire industry. This extends beyond the process itself, advanced tooling, along with instrumentation to monitor change right at the bench.

Read back a bit, seeing I'd posted earlier, and connected Mr. Branch to this. Never met him but sure studied his work. Not particularly effective on mild street engines of the 70's, but if you were looking for a little more, that was the place to start. Porting alters volumetric efficiency, while port matching is just good physics. The term matching is a little misleading, pattern conformity is better. certain cases proved a narrow edge beneficial, compared to an uninterrupted tract.
