AI Thread Summary
The discussion revolves around the validity of the adherence condition (u=0 at the wall) in turbulent flow within fluid mechanics. Participants confirm that this condition remains applicable even in turbulent regimes, despite complexities such as boundary layer separation. The conversation includes a humorous exchange about language barriers, with one participant expressing concern over their English skills while another struggles with Spanish. Clarification is sought regarding the implications of turbulent vortices near the wall, but the consensus is that the adherence condition holds true. Overall, the adherence condition is affirmed as valid in turbulent flow scenarios.

Hey I came into a doubt in the classical physics forums, and I want to know if I said something stupid.

Usually we employ in Fluid Mechanics the adherence condition (u=0 just on the wall, where fluid and solid meets; u=velocity field). But I'm not sure if in turbulent regimenes this keeps on being correct. Sure that boundary layer separates from the wall, or it is formed a turbulent one. Imagine a vortex near wall, do you think I can impose u=0 at the wall?

That statement is very convoluted.. can u clarify it?... do you need help translating.. tpye it in spanish

Esa declaración es muy complicada.. lo puede lo clarifica? ... lo hace necesita traducir de ayuda.. lo escribe en español. I can understand it better than i can type it, but that should get the point across
 
Sorry I missed this earlier, Clausius.

Yes, you can still impose u=0 at the wall in a turbulent flow.

:smile: My english is disappointing, but your spanish is the worst!. Anyway, Enigma seems to understand me after all. If what you are saying is true, it is certain I have said something stupid. See this thread:

got it.. and yes my spanish is crap i know... but u got what i meant.. like i said i understand it better than i write it
 

Thread 'Race car suspension Class'

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...

Thread 'Cantilever help'

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?'

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...
