Computer shaping of in-pile flow velocity field

A simple numerical algorithm permitting to find the law of radial variation of porosity of the shaping lattice placed in the inlet device of the reactor, at which the assigned shape of in-pile flow velocity field in the reactor core is provided, is plotted on the basis of numerical calculation of two-dimensional flow velocity fields in an anisotropic porous body. The numerical method for solution of hydrodynamic equations was tested by comparison with experimental data obtained when studying the process of mixing in the hydrodynamic model of the upper mixing chamber of the BN-600 reactor. Opportunities of the suggested algorithm are shown on the example of solving the problems of hydraulic shaping. Its operability at rather complex vertex flow picture in the inlet device is exhibited
