Fluid Mechanics: Upstream Pressure Distribution

AI Thread Summary
The discussion centers on the differences between theoretical and actual surface pressure distributions upstream of the separation point in fluid mechanics. Participants explore the reasons behind the variations, emphasizing factors such as flow separation, viscosity, and boundary layer effects. The conversation highlights the complexities of real fluid behavior compared to idealized models. Understanding these discrepancies is crucial for accurate predictions in fluid dynamics. The need for clarification on these concepts indicates a broader interest in the implications for engineering applications.

A few things I don't quite get... about why the surface pressure distribution UPSTREAM of the separation point of a body is different to the theoretical or ideal distribution...?

I can see why there will be a difference between the theoretical static pressure distribution but not why the surface pressure distribution upstream will change.

Thanks

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 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...
