Accelerating motion of a vertically falling sphere in incompressible Newtonian media : an analytical solution
The transient motion of a sphere falling through a Newtonian fluid has been investigated using a drag of the form given by Abraham/Wadell, the average accuracy of which was found to be 7.6% for a sphere with Reynolds number Re in the range 0 less than or equal to Re less than or equal to 10(4), 12% for 10(4)
