At this present research paper, solid particles jet into turbulent cross-flow trajectories and turbulence structure adaptations are presented for a non-reacting (No combustion) flow conditions. Additionally, the particle-source-in cell (PSI-CELL) methodology is used to achieve coupled (CFD-DEM) calculations. In the following research paper, a fully real fine-sized jet of Polyethylene with a mean diameter of (3.6 mm) has been taken as the solid jet into the carrier phase. The conveying velocity and the solid particles loading ratios during the experiments were varied from 7 m/s to 12 m/s, and 0.270, 0.610, 0.950, respectively. Both experimental and simulated findings reveal that the gas-phase velocity pattern in the horizontal direction takes an asymmetrical trend with solid increased particles loading ratio below the lower portion of the cylindrical channel. The findings of simulation and experiments demonstrate that the turbulence intensity within both radial and central areas of the cylindrical channel is greater than those presented in near-wall areas. Evidently, the velocity and pressure of the main flow field will decrease. There are improvements in the turbulence intensity about (240%) in some areas along with cross-section of the cylindrical channel.
