 I suspect I'm not understanding your point.

 When you say "translational kinetic energy" are
 you
  a) including KE tied up in the overall flow of
 the fluid
  b) or including only the KE of the random motions
 of the individual particles !!relative!! to the
 overall flow?

 The equation you wrote seems to force you to include
 the overall KE in the calculation of thermal energy,
 but as far as I can tell that's not the right way to
 go.

 Reply to the list if you think they'd be interested.>>>>

 John's point is well taken here. The equation I wrote is ambiguous as to
whether I meant to exclude the non random kinetic energy of the molecules
though this is what I meant to do. However in my confusion I asked the naive
question whether nature would care about (in my very first post). our
definition of thermal energy and whether a temperature measurement made on an
object in motion relative to an observer would in fact indicate a higher
temperature. After all the molecules of an object in motion must have higher
KE than that same object at rest with the same random KE. Well, having come
full circle the value of this question becomes obvious.
