Head Nedopekin F.V., Registration Date 29-02-2008 Organization Donetsk National University popup.description2 The mathematical sample piece is developed for the personal computer and the computing algorithm of hydrodynamical processes in a tundish ladle in three-dimensional statement is formulated. In a problem nonlinear equation Navie-Stoksa in approximation of turbulent viscosity, sample piece Prandtliy is realized. Numerically the problem is solved by means of integration-interpolation a method of the "indignant" operator, a difference against a stream, a method of variable directions and prorace. At the assaying of vortical structure it is visible, that in the left part of reception section the vortical structure is less developed, than in right. It speaks that submission of a jet of metal is carried out more close to the left partition. Uniform intensity of agitation is observed only in a drag of section. All this allows to draw a conclusion, that speeds of the expirations of a melt from channels of partitions at casting section will be different, that can lead to growth of quantity of nonmetallic which get with a melt in a crystallizer pan Product Description popup.authors popup.nrat_date 2020-04-02 Close
