Development of Methods of Gas Flow Computation in Short Diffusers

The paper suggests numerical and experimental computation methods of gas flow in short diffusers. The results of numerical investigations, carried out in ANSYS CFX for thirteen variants of turbulence, as well as experimental results are presented. For turbulence model k-ω, good repeatability of experimental data is obtained. The possibility of numerical computation methodology implementation while developing critical infrastructure systems with short diffusers is proved.
