Sources for optimally sizing a sump
Sources for optimally sizing a sump
(OP)
Anybody here know of a good reference on sump design? Specifically determining the optimal size of a sump? Effect of baffling? I have scanned most of the sources I have ready to hand and can't find any coverage. I know there is some minimal cooling effect, but since the surface area rises as a square and the volume a cube, it would seem to favor a smaller sump though you would obviously want some level of thermal inertia. Cavitation issues would also merit some attention, and I would expect that depending on the oil used, sump design would effect how particulates settled out (depending on the total design that might or might not be a desired effect). Any body here seen any good sources?

you probably don't want to plan to collect sludge in your pan - better to put it in the filter.
you do want to have few enough "turns" of the sump volume to allow deaeration of the oil.
another key driver is the oil change interval you'd like to advertise. On many industrial & transportation diesels, that factor drives the sump size upward more than any other contributor (packaging & cost push down).

For reliability, fit the LARGEST oil tank possible/practical within the aircraft's framework.
For production cost, fit the SMALLEST tank that will still get the job done within FAA safety limitations.
That seems simple enough for dry sump.
Wet sump aircraft, e.g., a replica F2 with a 350 SBC are about and, look, sound great...just make sure don't do any positive g pushovers or any
