I redid the model a bit, added the stylistic wings on the top grille and added the radiator cowling/outlet duct.

So flow seems to slowly enter at the bottom - and it looks like it's exiting at the top... That doesn't fly so well with me - but I don't really have a method of testing this....



What also doesn't fly for me is the hood... That big blue zone is all pointing the wrong direction - forwards.... Tuft testing really didn't show that. I think I'm going to need to do some flying tufts to see what's happening a couple inches above the hood....


Here's the overall setup


So why am I modeling the internals now? Am I getting too far ahead of myself? Well, the books I've been reading lately have been stressing that internal flow interaction will change external flow. Thus far, that is obvious - but we still look good for the JettKamm.... I'm essentially narrowing in on the 18.5 degree design for ease of manufacturing and easy of assembly/use.

I don't think I can make the model much more complicated - even these relatively "simple"/"low cost" runs are taking significant chunks of time and memory.

If anyone has some SODIMM DDR1 memory (1GB sticks up to 2 sticks) they'd like to donate

Next up - high resolution of the model above - for baseline
