Аннотация: This paper presents the results of numerical simulation of twodimensionallaminar flows near a regular system of cylinders, forming a plane latticeperpendicular to the velocity vector of the oncoming supersonic flow. A multiblockcomputing technology is applied using local curvilinear grids adapted to the surfaceof bodies and having finite areas of overlap with a global rectangular grid. The viscousboundary layers are resolved on the local grids using Navier–Stokes equations.The interaction of shock-wave structures and aerodynamic wakes behind the elementsof the lattice is described within Euler equations. With a sequential increaseand decrease in Mach number of the oncoming flow, several rearrangements of theflow structure near the grid are found. A multiple hysteresis was revealed, whichis expressed in the fact that the flow structure and aerodynamic loads on the latticeelements depend not only on Mach number but also on the history of its change.https://doi.org/10.1007/978-981-15-2600-8
