| Abstract: | The present paper deals with the entrance flow at low Renold number in a finite circular cone.The collocation method is used to solve this problem.In order to overcome the ill-conditioning of the matrix of the linear system,the least-square method and the modified Gramm-Schmidt orthogal process are used.Finally the velocity distribution in the entry region is obtained. |
