Vortex-Induced Vibration of a Circular Cylinder at Low and Subcritical Reynolds Numbers-Part I: Low Reynolds NumbersBy Sintu Singha, K. P. Sinhamahapatra
Abstract: The vortex-induced vibration of a circular cylinder at low and low subcritical Reynolds numbers is studied numerically over wide ranges of the influencing parameters. The cylinder dynamics is modeled using a spring-damper-mass system and the fluid dynamics is simulated using the two-dimensional approximation. An implicit, collocated moving grid finite volume algorithm implemented on an unstructured triangular mesh is adopted to solve the fluid dynamic equations. The numerical simulation confirms that …

Numerical Simulation of Low Reynolds Number Incompressible Flow over Two Side-by-Side Circular CylindersBy Sintu Singha, K. P. Sinhamahapatra
Abstract: A second-order accurate unstructured collocated implicit finite volume method based on the primitive-variable formulation is used to study the flow field around a pair of cylinders arranged in side-by-side configuration. Numerical simulations are carried out for long time on a high-resolution mesh to obtain the appropriate evolution of the overall flow field and vortex structure of the wakes. A wide range of gaps between the cylinders is considered over a …
