The paper examines, by means of highly resolved large-eddy simulations, the fluid mechanic behaviour an incompressible, turbulent flow separating from axisymmetric, hill-shaped obstacle. hill is subjected to a flat-plate boundary layer thickness half height, developing within large duct in which placed. Reynolds number based on height and free-stream velocity 130000, momentum-thickness 7300. Extensive detailed experimental data are available for these same conditions, compared with...
A method to generate inflow boundary conditions for large-eddy simulations (LES) of turbulent free shear layers is presented. time series instantaneous velocity planes, with duration approximately equal the integral scale flow, extracted from a periodic simulation and saved on disk. This signal transformed into one, by using conventional windowing technique, re-used in actual as many times required obtain converged statistics. The applied LES spatially developing mixing layer. It shown that...
Abstract The paper investigates, by means of a simulation methodology, the flow separating from 40 degrees backward-swept wing at 9 incidence and Reynolds number 210,000, based on wing-root chord length. Simulation corresponds to LDA, PIV suction-side-topology measurements for same geometry, conducted other investigators specifically provide validation data. finest block-structured mesh contains 23·6 million nodes is organised in 256 blocks maximise quality facilitate parallel solution...
Given unsteady operating conditions, the combustion process in gas turbine combustor often suffers from equivalence ratio fluctuations (ERFs), which induce instability. In this study, effects of ERFs on a swirl-stabilized premixed flame were studied by large eddy simulation (LES). A new model with turbulence modification and two-step methane oxidation mechanism employed to simulate interaction between chemical reactions. LES was first validated comparing results corresponding experimental...
