Core Jet Potential

AI Thread Summary

The term "potential core" refers to a region in a jet where mean velocity gradients are absent, indicating a stable flow. This area is characterized by potential flow behavior, meaning it behaves as if it is inviscid, or free from viscosity effects. The name reflects the core's adherence to the principles of potential flow, which simplifies analysis and understanding of jet dynamics. The potential core is crucial for understanding the jet's overall behavior and performance. Thus, the designation emphasizes its unique flow characteristics within the jet.

Why is a "potential core" region of a jet called a "potential core"?

We all know that there exists a region called "potential core" in a jet where there are no mean velocity gradients. My question is, why is it called a "potential" core?

It obeys potential flow rules, aka it is essentially inviscid.

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/
