As well as, simulation results demonstrate that the modified Frehlich spectrum and the modified von Karman spectrum have little difference on the beam spreading for partially coherent beam propagating in atmospheric boundary layer turbulence.
Simulation The curve in Fig.1 show that beam spreading radius w varies with initial emission radius w0 when propagation distance and initial zenith radian are fixed.
The simulation demonstrates that Eq. (14) represents well the w variation with z and θ, namely with the propagation height zcos(θ) and the two curves respectively derived from the modified Frehlich spectrum and the modified von Karman spectrum are very close.

The results of computer simulation modelling of backfill of spherical particles of two standard sizes are presented in the activities of scientists [25].
The simulation results were tested on field experiments in the manufacture of some structurally inhomogeneous material, which proved the high efficiency of modelling.
In scientific experiments [30, 31], a simulation simulation of the packaging of non-spherical elements (ellipsoids) is presented, which mainly have an irregular shape of elements and do not take into account the sphericity coefficient.
Purpose of the work is to develop a computer simulation model for the study of a heterogeneous environment, as well as to simulate the packing of elements of an elliptical (irregular) shape.

As shown in Fig.1, a two-dimensional (2D) simulation was chosen to analyze the turbulent flow in a horizontal channel with obstacles placed in the center of the channel.
The incompressible Navier-Stokes equations are used to solve the problem and are expressed as follows [24]: Continuity equation: (1) Momentum equation: (2) Energy equation: (3) Where Γ : molecular thermal diffusivity Γt : turbulent thermal diffusivity The standard k-ε model is a popular choice for CFD simulations because of its ability to provide good quality results at a relatively low computational cost.
For the numerical simulation, a mesh study was carried out with the aim of balancing the quality of the results obtained with the CPU time.
