Abstract
To build fishing gear, nodal sections with different orientations of the del are used: T0 (standard mesh arrangement); T90 and T45 (T0 rotated by 90° and 45° respectively). The paper discusses the use of this method to determine the hydrodynamic properties of objects with different mesh rotations. A schematization of the canvas was carried out to develop a mathematical model based on the Navier-Stokes equations. The calculation was performed on a regular computational grid using an implicit finite-difference scheme using the methods of coordinate splitting, linearization of nonlinear equations with subsequent correction of nonlinear coefficients, as well as rhenium of tridiagonal systems by the sweep method. The paper presents the results of numerical experiments in the form of visualization of pressure on the surface of various mesh structures at different angles of attack.
