AI Thread Summary
Compressible flow in ducts undergoing heating or cooling can lead to non-intuitive property changes, particularly in Rayleigh flow. While mathematical calculations for property changes from inlet to outlet are well-documented, visual representations of the flow dynamics within the duct are lacking. The discussion raises questions about whether heating or cooling creates an artificial nozzle effect at the duct walls and whether temperature distribution is uniform across the duct's cross-section. Suggestions for resources include a specific MIT link for visualizing compressible flows. Overall, the need for better visual aids to understand these phenomena is emphasized.

Been trying to find out what compressible flows would look like, to picture why you get the not so intuitive property changes.

Started with looking into what might be happening in Rayleigh flow. Theres plently of examples on how to use maths to calculate property changes when going from inlet to outlet of a duct, but I've not been able to find anything that gives a visual picture of what is happening with the flow within the duct and at the heating/cooling point.

My reference material has been this book link to pdf copy of Fluid Mechanics: Fundamentals & Applications (link to copyright book removed by moderator) , Rayleigh flow starting at page 693 of the book (718 of the PDF).
And the table for Rayleigh flow property changes, Table 12-3 on page 696 (721 of pdf).

Should I be thinking of the heating/cooling causing a creation of an artifical nozzel out of the affected fluid at the wall of the duct?

Is the heating/cooling of the fluid meant to be equal across the cross section of the duct at the one point?

Cheers

After deleting a link to a PDF textbook copy of questionable origin, this thread is re-opened.
 
If anyone has any suggestions on where to look or who/where to ask about visualising compressible flows, that would be welcomed as well.

Cheers
 
Thanks onatirec.

Interesting video. Its those sorts of images and ideas that make me think maybe theres a nozzel being created out of the affected fluid, but thats just my crazy thoughts at the moment.

Cheers
 
Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...
I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
Thread 'What's the most likely cause for this carbon seal crack?'
We have a molded carbon graphite seal that is used in an inline axial piston, variable displacement hydraulic pump. One of our customers reported that, when using the “A” parts in the past, they only needed to replace them due to normal wear. However, after switching to our parts, the replacement cycle seems to be much shorter due to “broken” or “cracked” failures. This issue was identified after hydraulic fluid leakage was observed. According to their records, the same problem has occurred...
