Ecological Systems and Devices Annotation << Back ESTIMATION OF STABILITY LIMITS OF AIR INTAKE OPERATION USING EDDY-RESOLVING TURBULENCE MODELS A.A. Utkina, A.S. Kozelkov, A.V. Kornev, R.N. Zhuchkov, N.S. Spirin The paper presents the technology and results of the flow problem numerical simulation in the air intake. An original approach was applied to constructing a technique for modeling separated flows for a problem with a complex geometric shape, including a method for constructing a computational model and developing numerical methods that make it possible to perform high-precision simulation on a grid of arbitrary polyhedrons. The presented algorithm allows not only to analyze the flow around full-size objects, but also to significantly improve the calculation accuracy when modeling separated flows, which brings the modeling of separated unsteady turbulent flows in solving industrial problems to a qualitatively new level of accuracy of modeling unsteady flow around various bodies. Keywords: discrete model, Enhanced detached eddy simulation, SSG/LRR-ω/EDES model, air intake. DOI: 10.25791/esip.5.2022.1297 Pp. 19-30.
