Reservoir oil tank baffle design
Reservoir oil tank baffle design
(OP)
Any help or ref much appreciated. I did a search for existing threads but not much was there. I am looking for any info, references, or suggestions when designing baffles that go inside a reservoir oil tank that can be used to help prevent trapped air from entering the supply line.
The situation is a reservoir tank with a supply line at the bottom and return line at the top. This is a non pressurized tank. The pump is sucking oil from the supply line to an engine then loops thru a cooler, filter and then makes its way back to the tank. It is a square tank that will hold an oil volume of 40 gallons.
Thanks.

reason to use baffle plates in an oil tank can be:
-structural integrity of the tank
-prevent oil from slushing back and forth (ships)
-allow solids to settle out
construction details:
-scallops in corner of tank, connecting the compartments
-suction on 1st compartment, return on last compartment

It is better to have enough ideas for some of them to be wrong, than to be always right by having no ideas at all.

Aeration of the reservoir oil can be mostly eliminated by use of de-aeration devices such as swirl tanks or centrifuges. However, these devices normally require a scavenge pump, since they are located in the return flow. Here's an example of a swirl tank:

If your system has no scavenge pump, your best option is to make sure that the oil volume turnover rate is as low as possible. Sometimes a screen mesh divider placed mid-level across the tank will help to discourage air bubbles migrating downward.
hope that helps
