No doubts for me, except some small points:
Yes, K1.4
You kind of got us there. A bit further up the yellow part says 60mm, though.
No, I got rid of the txt files, that is why you now these parts have to start with a certain name according to K1.4.
I confirm that the old mesh/numerical scheme the new exhaust bc works very well (distance between exhaust surface and measure/bc surface 150mm).LVDH wrote: ↑Wed Jun 21, 2017 7:34 amYes, during the winter we discovered that it did not make too much sense that the amount of volume flow leaving the engine is that same that enters. According to Machin/Richard the density in the exhaust is about half compared to the surrounding air. I almost assume that it should even be more than it is now, but I did not want to add a source of numerical instability. I hope how it is now is a good compromise.

This is something that bothers me: I have never seen a flow report for intake or exhaust. I've ran 100s of interactions but never took part in an actual race. Is it supposed to show on my reports? Where? How?CAEdevice wrote: ↑Wed Jun 21, 2017 8:07 amI confirm that the old mesh/numerical scheme the new exhaust bc works very well (distance between exhaust surface and measure/bc surface 150mm).LVDH wrote: ↑Wed Jun 21, 2017 7:34 amYes, during the winter we discovered that it did not make too much sense that the amount of volume flow leaving the engine is that same that enters.

This should be legal as long as those curved elements can be considered as the "thin elements" specified in K3.4. When you submit your entry, those parts should be separated from the main body, and included in the "high_res_surfaces" directory.rjsa wrote: ↑Wed Jun 21, 2017 11:03 amReposting from 2016:
Another question:
I'm reviewing my design against the rulebook.
The last paragraph from K3.3: "there must be no gaps in any of the sections formed"
Now this:

My doubt: A Y normal plane crossing the rounded internal diffuser surface would create more than one separated section, being each on of them separate but closed curves. Is this valid?

To cut out the diffuser strakes (especially if they are "3D" and with a "3D" diffuser) is not so easy. Would not be better to apply a mesh control with a box in the diffuser volume?This should be legal as long as those curved elements can be considered as the "thin elements" specified in K3.4.

Yep, I did that already, after the rues were published.cdsavage wrote: ↑Wed Jun 21, 2017 1:11 pmThis should be legal as long as those curved elements can be considered as the "thin elements" specified in K3.4.

A 3D diffuser, with less than 25mm walls could go entirely in the high res area.CAEdevice wrote: ↑Wed Jun 21, 2017 1:44 pmTo cut out the diffuser strakes (especially if they are "3D" and with a "3D" diffuser) is not so easy.
