| Abstract: | The velocity profile of the laminar flow in axisymmetrical convergent wedge-shaped spherical clearance is influenced by the specific shaped clearnce.The approximate expressions of the entrance region lengeth and the velocity which are anexplicit function can be obtained by using the energy integral eguation in sphericalcoodinatates.And the flow resistance is analyzed. |
