Fluid Mechanics: Upstream Pressure Distribution

Click For Summary
SUMMARY

The discussion centers on the differences in surface pressure distribution upstream of the separation point in fluid mechanics. Participants highlight that the observed pressure distribution deviates from theoretical predictions due to factors such as viscosity and flow separation. Theoretical models often assume ideal conditions, which do not account for real-world complexities like turbulence and boundary layer effects. Understanding these discrepancies is crucial for accurate fluid dynamics analysis.

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
