vortex at the tank outlet
vortex at the tank outlet
(OP)
Hello All,
I need to get some sources about the theory of the vortex formation at the tank outlet and vortex breaker design to prevent the vortex.
The tank is a 21 meter height and 92 m diameter crude oil tank.
Outlet pipe is 48".
There are some formulas which is related with froude number and swirl number. I put a device at the outlet of the tank to decrease the froude number to prevent vortex formation.
Thanks in advance...

Another common reference, the Durco Pump Engineering Manual, also gives a submergence vs velocity chart but does not include details on vortex breaker design.

In what country is the tank located ?

but I guess these are for water. can I find a formula for crude oil.
RE: vortex at the tank outlet
if you did put a voetex beaker according to what design? did you have problems in pump suction (cavitation?).
is the outlet nozzle located at bottom or side of the tank?
also if you keep some level in the tank you will not have vortex formation.
did you know that the direction of the vortex swirle depends if the tank is located in the north or south of the globe?

Can you explain a bit more about this, please?

There is something on tanks, too in the above article.
