flow over a sphere
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.
