LIM coolant flow
LIM coolant flow
(OP)
Please excuse me, I know very little about fluid dynamics.
Please see the links below to see a LIM of a GM 3800

What you see here is the main passage to transfer coolant from the back half (right) to the front half (left). In these pics, you see a cut that is approximately ¼" deep x ¼" in height to increase the flow. Increasing the flow reduces the temperature in the back half and reduces the temperature differences between the halves. I would like to make a spacer that does not have the web between the two passages to increase the flow. Could some one give me a bit of guidance if making this spacer will increase the flow?
Thanks for your help
Mike

If handicapped by lack of adequate or appropriate machine shop tools, sandwich two plates to the area with an over sized hole in the inner plate.

RE: LIM coolant flow
The flow in your coolant system will be a function of all the pressure drops (restrictions) throughout the entire circuit, both before and after your divider. The flow will always take the path of least resistance. Enlarging that cross-over passage may have a big effect, or possibly no effect at all if there are other restrictions in the system.
Also try not to change cross-section too rapidly in your coolant passages. A point of abrupt pressure drop in the flow can actually create conditions for cavitation, which would cause local overheating.
Good luck.
