VORTEX BREAKER
VORTEX BREAKER
(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. I put a device at the outlet of the tank to decrease the froude number to prevent vortex formation.
Thanks in advance...

If you have Shell contacts, standard drawing 10.010 covers bottom outlet vortex breakers up to 24". This would extrapolate for 48" ND to a 72" circular plate (1.5ND) located 24" (0.5D) above the outlet on 16-20 radial baffle plates.
Also NFPA 20 has a design for side outlet nozzles in the appendix.
