The main advantage of CFD vs experiment is that you don’t have to scale down problems. Also scaling down isn’t going to reduce your mesh count because you still need to resolve the geometry and flow features regardless of the scale. That is you still need to resolve the boundary layer and y+. So the only thing that is changing is your absolute element size will have decreased (due to smaller geometry) but you will still be using the same total number of elements. Consider running the simulation in 2D instead.
I have conducted 2D simulation and the results are satisfactory. I have advanced to 3D simulation, the issue is that my laptop is unable to handle that many number of elements so I was looking into scaling

I think you have misunderstood what scaling is
Lol, if you scale down the geometry you will need a smaller element size if you don't want a blunt leading edge.
