Quote:Originally Posted by LTD02 for practical purposes, the point of onset of minor turbulence is where the port begins to audibly chuff. Again, not correct. Chuffing is massive turbulence, not minor turbulence. The onset of...

Quote:Originally Posted by Ricci Simulations scale in a perfectly linear manner. They do not for the most part attempt to address large signal deviations that occur in the system due to a large variety of factors. Never mind the t/s...

http://wiki.answers.com/Q/What_is_the_speed_of_the_average_sneeze That's the first google hit for average velocity of a sneeze. 40 - 100 mph. Approximately 45 m/s at the high end (if I did the math right). Flare It says core limit...

Quote:Originally Posted by LTD02 "Yes, ok, that's what I said in the first place, many many posts ago." i meant that your thinking that 20m/s was your failure point, not that 20m/s is your failure point. at 10m/s, you are at the...

Quote:Originally Posted by imagic This effect can be observed with a kitchen funnel and rice grains, but also in freeway traffic. Go to 2:20 in this video: Nice video. This is (very basically) what Flare It calculates. Unless...

Quote:Originally Posted by LTD02 "Wouldn't that be analogous to including Flare It results directly within the program? I admit that would be cool for ALL the simulators to have but since we can use Flare It separately I don't see...

Quote:Originally Posted by LTD02 "Increasing velocity even further, the air in the "core" of the port becomes turbulent. Yes, exactly what I said. Core velocity limit (red line) is the ONSET of compression, not the failure...

Quote:Originally Posted by LTD02 "I've asked at least a dozen times where you guys think the model breaks down. I've received no answer at all." chuffing is where turbulence begins. turbulence is where you get complete compression. ...

Quote:Originally Posted by LTD02 "Like I said many posts ago, I don't expect audible chuffing until the core get up to 20 m/s or higher." well, there is your major failure point. Yes, ok, that's what I said in the first place, many...
