Simulation of a Submarine

hydrodynamicist · 12-17-10, 03:44 PM

Hello All,

I am new to your site. We simulate flow around ships and submarines. Our most recent work shows a Los Angeles Class submarine cruising on the ocean surface. The link is provided here:

I hope that enjoy the numerical simulation.

Best regards, Doug.

Doug,
very interesting, useful and beautiful!!!!
Thanks for sharing.

For the people who didn't understand the depth of what Doug posted here, I quote from his link:

Quote:

A 688 submarine traveling on the surface of the ocean is shown. The simulation was performed on a Cray XE6 supercomputer using 6,144 processors. The simulation ran for 19,000 time steps and completed in 36 hours."

(I underlined the obviously interesting - I think- parts).

OMG I am so amazed and wowed by this! Thank you so much for letting us know about this!

This looks so uber awesome!

Howdy. And that video is mighty cool.

if memory serves me right, Skip Tyler in the book Hunt For Red October used a Cray supercomputer to test the theory that the Red October was using the magneto hydrodynamic drive that made it practically silent. Is that the same thing as you guys are doing here?

It's mindboggling to wrap your head around what goes into things like this.
welcome aboard and thanks for sharing!

Our goal for the 688 was just to show that we can model a complicated free-surface flow. Given that goal, we did not include many details of the boat, and we just focused on the flow around the hull. -Doug.
