Hi,

I was wondering if someone knows the limits of the SIMPLE algorithm.

What is the maximum speed that it can work with?
Is it limited by the Reynolds number?

I'm asking these questions because of my code. I've developed a small code that calculates the flow field in 2D. But, I've noticed that if the entry speed is high, the code goes bananas. Now my code is stable with entry speeds below 2 m/s and density of 1.

I haven't found a proper reason for this. I've been reading the books by Versteeg and Anderson, but I cannot find something that I can use to justify the behavior.

Please, I will appreciate any help, or the name of a book that I could read.
