Nice work!



Are the TC's actually attached to the intake tubes and the flange in front of the oval radiator tube using Kaptan tape (surface mount TC's?) If so, I
would think you would be measuring the temp of the plastic and not the air in those locations. If anything, they would read false highs, and tend to flatten out the profiles.

Maybe suspending the TC's on an insulating (wood?) dowel in the airstream would be the way to go.

I saw much the same result in a lillte experiment of my own, however using the NI modules is a better, normalized way to go!

I'm not just blowing wind here, I make and design gas and embedded material thermal measurmentsystems all the time. If you are trying to measure gas, the TC must be supported, by a thermal insulator, in the media to be measured so as not to skew the results.
