In a steady flow, condition (4) is equivalent to the condition that the velocities at the points of $ S \cap \Sigma _ {j} $ be finite. The shape of the surfaces $ \Sigma _ {j} $ is unknown in the course of solving ... WitrynaHence, since one can derive the impermeability condition with respect to and ,it follows also . Thus, by summing up, one sees that vanishes at the boundaries. In conclusion, one can write Finally, either the divergence of the velocity is zero at and then for all ,or it decays exponentially to zero. greenwall health scholars
