In the article leads results of the tree-teeth labyrinth seal flow modeling obtained with ANSYS-CFX. The results were compared with experimental data acquired on test facility «Dynamic Seal Model». Experimental data allowed to compare measured pressure distribution along chambers and in circumference of the rotor in the chamber’s centers. Such integrated approach for verification of the modeling strategy and ANSYS-CFX permits more efficient using this software in engineering practice, seals design in modern gas turbine. Also it helps to find way to increase efficiency of the gas turbines through improving their dynamics. The article is useful for engineers specialized in aerodynamics and turbo-machinery.
