Sure thing, the solver I am working on is this one: https://gitlab.com/alie89/flubio-code-fvm.
It is a 3D, collocated, unstructured, finite volume solver for incompressibility NS. I can run steady, unsteady and I can use SIMPLE, PISO and Factional step method (both explicit and fully implicit momentum). I can also solve for turbulence (k-omega, BSL, SST, Spalart-Allmars, LES). I have also implemented some kind of Immersed boundary (2D/3D) that I need to resume at some point. Hot topic of the moment, I am developing a fully coupled pressure based solver using field-split. What I have now is working ok, I have validated it on a lot of 2D problems and going on with 3D right now. If all the tests are passed, I'll focus on tuning the field splitting which looks to be a quite interesting topic! Flubio is a project I have been carrying on since PhD days. The implementation is 99% on my shoulders, despite the fact I am collaborating with some people around. I am coding evenings and weekends/free time, it gives me a lot of satisfaction and also a lot of insights!
