Hi Chan
Flow separates where there is reverse flow close to the surface of the sphere. This normally happens around 80 degrees for lamianar bl and 120 deg for turbulent bl. I donot know why does it separate before 90 deg in lamainar case as there is favourable pressure grdient on the front surface. Do have some idea.
