| Title of the article | Method of collocation for equations of the problem of motion |
| Abstract. | This work contains a mathematical model of the problem of motion in the axisymmetric channel. Numerical solution of equations for the problem of motion is proposed to calculate using the collocation method. For this purpose in the field of integration as a collocation nodes Chebyshev nodes of the first kind are taken. Given the computational scheme of the method of collocation, which leads to a system of linear matrix equations, which is solved by the method of the matrix is constructed. The results of numerical solutions in the form of the distribution graphs of velocity vectors and the pressure of a flowing part of the study of the channel are resulted. It is shown that the results of this study are consistent with the results obtained earlier by the author with the help of other computational methods. Together with differential methods it is expedient to use a collocation method for the solution of problems of hydrodynamics of a current of viscous liquid in rotating and motionless canals. |
