FLOW INDUCED CYLINDER OSCILLATION AND ITS CONTROL WITH HIGH ORDER SPECTRAL DIFFERENCE METHOD ON DEFORMABLE MESH
SPECTRAL DIFFERENCE METHOD DEFORMABLE MESH
2015/7/3
In the recent work by the authors, high order spectral difference (SD) method has been formulated in a framework with dynamic deformable meshes, and been demonstrated to preserve the design accuracy o...
Delaying transition in Taylor-Couette flow with axial motion of the inner cylinder
Taylor-Couette fl ow axial motion
2014/12/30
Periodic axial motion of the inner cylinder in Taylor-Couette flow is used to delay transition to Taylor vortices. The outer cylinder is fixed. The marginal stability diagram
of Taylor-Co...
