  THE ANALISIS OF SAINT-VENANT EQUATION SYSYEM ANALYTICAL AND NUMERICAL METHODS

  01.00.00 Physical-mathematical sciences

  Tags: sweep method fission method flow discharge saint-venant equation system diffusion-convection equation
  Description

  Diffusion-convection equation that has been received from Saint-Venant differential equation system describing nonstationary fluid motion in a river canal is investigated. Analytical method is considered for the solution of equation with the fixed factors and finite-difference method is considered for the solution of equation system with the float factors. The results of test calculations executed for a reaches of the river Kuban are presented

  CONSTRUCTING THE APPROXIMATE SOLU-TION OF THE TWO-DIMENSIONAL PROBLEM FOR THE EQUATION OF DIFFUSION WITH DEPENDING ON CONCENTRATION COEFFI-CIENTS AND SOURCE FUNCTION

  01.00.00 Physical-mathematical sciences

  Tags: the diffusion in the isotropic environment boundary problems with the nonlinear equations the method of basic potentials nonlinear source function
  Description

  In the article with the help of a technique, based on discretization initial problem of time variable and the method of basic potentials, is constructed the approximate solution of the second two-dimensional problem for the equation of diffusion with depending on concentration coefficients and source function. The general view of the approximate solution of this problem is reduced. On concrete example convergence of the approximate solution of the problem to the exact is shown
