I found this old post on vortex breaker designs and it relates directly to an issue I have now.
thread378-36635
I have a liquid full FWKO where the oil/water interface is only 12" off the bottom of the vessel. The outlet nozzle is 6" and the current vortex breaker is a crossed plate with a height of 6". Hence, the interface is only 6" above the vortex breaker.
This vessel is on a floating offshore platform and the client notices spikes in the oil in water content during rough weather.
We've suggested to our client to put a cover plate on top of the vortex breaker to fource the nozzle to draw water from the bottom of the vessel and eliminate the possibility of down flow from the interface level.
Our client likes the idea but wants to get a quantitative assessment of the improvement in water quality by adding this plate. We've lined up a CFD analysis of the fluid flow inside the vessel. Now the client is interested in a qualitative assessment - meaning is there any empirical or historic data showing the benefits of vortext breakers in general and vortex breakers with cover plates in particular.
Does anyone know of any technical papers, or texts, or any other source that might have this kind of parametric data on the benefits of vortex breakers?
We are still suggesting the CFD analysis as the only way to be sure of the benefits for this specific application, but my client still would like some historic information on vortx breakers.
