What is the method for calculating the angle Θu in compressible flow?

AI Thread Summary
The calculation of the angle Θu in compressible flow is related to the surface inclination and the no-penetration condition. Unlike previous examples that require fluid properties post-deflection, this situation focuses on pressures. Understanding the relationship between surface angles and flow properties is crucial for accurate calculations. The method emphasizes the need for clarity on how these angles are determined in relation to the flow direction. Accurate determination of Θu is essential for analyzing compressible flow dynamics effectively.

Hello good people!

I'm studying the compressible flow and the book refers to this example. I can't understand how does it calculate the angle Θu?
In the previous example, there is a method to calculate it but it requires all the properties once the fluid is deflected, therefore, that's not the way because they are asking for the pressures.

anything light is greatly appreciated.

Much like ##\theta_l##, ##\theta_u## is set by the surface inclination due to the no-penetration condition.
 

Thread 'Space Stuff and Launch Info'

Due to the constant never ending supply of "cool stuff" happening in Aerospace these days I'm creating this thread to consolidate posts every time something new comes along. Please feel free to add random information if its relevant. So to start things off here is the SpaceX Dragon launch coming up shortly, I'll be following up afterwards to see how it all goes. :smile: https://blogs.nasa.gov/spacex/
