摘要：
Combining boundary-layer theory and experimental data for the pressure distribution and boundary-layer thickness over the surface of a sphere, the following expression was obtained for the drag coefficient: CD=1+ 9.06 Re 1 22 Using this formula as a basis, an expression was developed for relating the settling velocity of spherical particles to their diameter at any value of the Reynolds Number. The validity of such expressions discussed and compared with experimental data. © 1979.
