Sreedhar, Madhu; Ragab, Saad Large eddy simulation of longitudinal stationary vortices. (English) Zbl 0832.76038 Phys. Fluids 6, No. 7, 2501-2514 (1994). The large scale structures developing due to centrifugal instabilities in stationary longitudinal vortices are studied by large-eddy simulation. The dynamic subgrid-scale model is used to model the subgrid-scale stress tensor, and temporal simulation is performed so that adequate grid resolution can be obtained.The simulations are made for a subsonic flow at low Mach number of 0.2 based on the maximum tangential velocity and the far-field speed of sound, which makes the calculations very near the compressible limit. The Reynolds number was 100000, periodic boundary conditions were imposed along the axis of the vortex, and symmetry boundary conditions were used in two directions in the cross plane. New large-scale structures around the core of the Taylor vortex have been observed. These structures appear as counter-rotating vortex rings around the vortex core similar to donut- shaped structures found in a Taylor-Couette flow.
