Numerical simulation of laminar symmetric flow of viscous fluids.

In practice, there are many works dedicated to the drastic simplification of the Navier-Stokes equations and to finding their particular solutions that are very relevant for practice. These studies are usually based either on symmetry considerations or on the theory of concreteness and dimensions. In this article, a mathematical model of the motion of an incompressible fluid in a diffusion nozzle was created and numerical results were obtained. For this, the Nave-Stokes equation was reduced to a parabolic equation with Mises substitutions. Using the obtained numerical results, the longitudinal and transverse velocities of the fluid were determined [ABSTRACT FROM AUTHOR]
