Problem definition in the rate of movement is formulated. Finite - difference scheme is received. Numerical computation is received. The geometrical dimensions of zone of liquid flow with low speed are shown.застойная зона, микроструктура, вязкая жидкостьstagnant zone, microstructure, viscous liquid
