SIMULATION OF A FREE JET USING SEKUNDOV'S ONE-PARAMETER TURBULENCE MODEL
Main Article Content
Abstract
In the work, a technique is carried out, where the scale of turbulence in the one-parameter
model of A.N. Sekundova is determined through analytical equations, which is used to calculate the width of the
jet. For numerical implementation, the equations ofthe boundary layer are written in physical variables and an
implicit absolute stable difference scheme of the second order in the transverse and first order in the
longitudinal directions is used. To compare the obtained numerical results, experimental data from known
sources were used. The distributions of axial velocity and turbulent viscosity, profiles of axial, radial velocities,
turbulent viscosity in various radial sections are determined. It is shown that the boundaries of the expansion
are generally rectilinear, but at the end the jet narrows slightly
