That was the closest picture I could think of that would mimick the idea that I was thinking of. I am not really versed on the design elements of compressor wheels, however I could see some benefits from the grooves in the form of adhesion and channeling of the air.
Thanks for your input and thats the conclusion I had come to after doing some deeper thinking on the matter. Especially since the fuel is not introduced until very late in the compression stroke, the air characteristics would be dominated by it.
I appoligize for the misuse of the word "swirl". Obviously swirl is the rotation of air while turbulence is the tumbling of air.
I would like to think that depending on the size and location of the valve in relation to the bore and the port wall(s) in relation to the valve would promote the...
Thanks for all the replies.
I am ending that thought process with a conclusion that primary swirl will be a direct result of piston bowl design while leaving the valve/port design for optimized flow into the cylinder.
Thanks for the replies.
Yes I do understand the strength and cooling aspect.
I was just thinking in terms of fluid flow and how to optimize the velocity off of the valve to fill the cylinder.
Yes, modern day diesels are optimized however that gets thrown out the door when you port and...
Here is a picture of a turbo billet compressor wheel that shows a similar groove pattern to that of which I am thinking of.

First of all I would like to state that I have read and learned a lot off of the threads on this site. There are many, very knowledgable people on here.
As for my question, I would like to know if machining grooves onto the surface, just as the valve area expands off of the stem and exiting...
