    Submarine Vortex
Click For Summary
Moving submarines can create toroidal vortices, particularly if their design is suboptimal. The discussion highlights the ease of visualizing such vortices in controlled environments like swimming pools or bathtubs. The formation of these vortices is influenced by the submarine's shape and hydrodynamic properties. Poor design can exacerbate vortex formation, leading to potential issues in maneuverability and efficiency. Understanding these dynamics is crucial for submarine engineering and performance optimization.

Today I learned how easy it is to create and visualize toroidal vortices in a swimming pool. I bet this could be done in a bathtub.



Do moving submarines create a big toroidal vortex around themselves?

If you design them badly.

Care to supply any detail or a reference?
 

Thread 'Does acceleration affect impact energy vs constant velocity?'

I do not have a good working knowledge of physics yet. I tried to piece this together but after researching this, I couldn’t figure out the correct laws of physics to combine to develop a formula to answer this question. Ex. 1 - A moving object impacts a static object at a constant velocity. Ex. 2 - A moving object impacts a static object at the same velocity but is accelerating at the moment of impact. Assuming the mass of the objects is the same and the velocity at the moment of impact...
