3D Visualization of the separated fluid flows
For the detailed investigation of the 3D unsteady incompressible viscous separated fluid flows around a sphere (for 200 < Re < 700) and circular cylinder (for 200 < Re < 400) the direct numerical simulation and 3D visualization are used. For 3D visualization of the fluid flows around a s...

| description | For the detailed investigation of the 3D unsteady incompressible viscous separated fluid flows around a sphere (for 200 < Re < 700) and circular cylinder (for 200 < Re < 400) the direct numerical simulation and 3D visualization are used. For 3D visualization of the fluid flows around a sphere the definition of vortex core as a connected region containing two negative eigenvalues of the S2+2 tensor is used (where Sij and ij are the rate of strain and the rate of rotation tensors). The formation mechanism of vortices in the sphere wake for Re = 500 is described in detail. For 3D visualization of the fluid flows around a circular cylinder the 3D isosurfaces of the steamwise component of vorticity (i)x are used. |
