Hello, Could you please give me some information about why these fluctuations are happening, is this a problem? if it is how can i solve it, and what am ı supposed to do to reduce the velocity residuals

There are lots of reasons, so start by checking the cell and mesh quality, the latter included whether you're resolving the flow & temperature gradients sufficiently. From there look at the flow field, what is going on and why might there be an instability in the result?
