I know it may not even be mechanically possible to reach the speed of sound underwater (1,484 m/s); but this is just a theory.
After discussing with several people, what would happen if a submarine was to break the sound barrier underwater, a couple of interesting theories arose.
Going along the assumption that due to Air and Water both being Fluids, they then behave in similar ways...
When an aircraft breaks the sound barrier, and Prandtl–Glauert singularity occurs, would the same rule apply for underwater? Would the water that this submarine is traveling through, condense the water further? Would it become denser?
When diving into water from a great height with nothing to really pierce the water (i.e. For example belly flopping from a great height), it would be like hitting concrete because the water doesn’t have enough time to disperse. If this submarine were to go so fast, that the water doesn’t have time to disperse, would it be like this submarine trying to constantly penetrate a brick wall from a “standstill” (i.e. submarine and water wall traveling at same velocity). Does this link to the theory of water becoming denser from the condensation previously mentioned?
Or, (my favourite theory), would there be a big explosion underwater? A shockwave perhaps?
One last thing, due to the friction being so great on aircraft traveling faster than the speed of sound, and thus becoming extremely hot, would the submarine become extremely hot from the friction of water? Would the water cool down the submarine at the same time? Would the submarine become more brittle? (quenching; haha)
My mind is blown, your thoughts please.
