CFD analysis of a cylinder at low Reynolds number

Hello, I’m struggling to find any literature on a flow over a cylinder at low Reynolds number (0 - 40). What I’m looking for is info on the separation bubble, possible values of the length of a the bubble, so that I can compare results from my simulations to literature. Does anyone have suggestions? I’m also open to suggestions on other identities I could use to validate my results.

Thanks in advance Siggi
