I know many of us regularly use the PIMPLE algorithm and many also inspected the source code and played with the iterations in the different loop levels.
We get good results from it.
There is also valuable information made available by Tobias Holzmann in the wiki and in his book.

But, unlike for SIMPLE and PISO algorithms, I have not seen any paper which actually describes the implementation from a "numerical methods" point of view.

In the git of the code I could find this commit which seems to go back further in time than the Foundation's git but it still doesn't give much information.

Is anyone aware of the history of the PIMPLE algorithm and whether any paper on its implementation details from a numerical point of view is available?
