Numerical Simulation of Flow Around Two Side-by-Side Circular Cylinders at High Reynolds Number

Discrete vortex simulation of the separated flow around a rotating circular cylinder at high Reynolds number

The separated flow around a rotating circular cylinder is investigated by the discrete vortex method combined with the boundary layer theory. The Keller Box method is used to solve the laminar boundary layer in order to determine the separation points on the upper and the lower sides of the rotating circular cylinder. The nascent vortices are then introduced near the separation points. A discre...

3D Numerical Simulation of the Separated Turbulent Shallow Flow around a Single Side Obstacle

In this paper, the performance of Reynolds Averaged Navier Stokes (RANS) simulations was evaluated to predict the flow structure developed by the presence of a sidewall obstruction in a uniform open-channel shallow flow. The study of these flow structures is important because they present in several real world configurations, such as groynes in rivers, where the erosion processes, mass transpor...

Numerical simulation of three-dimensional flow around two circular cylinders in tandem arrangement

Three-dimensional fluid flow around two circular cylinders in tandem arrangement is computed by the finite difference method without a turbulence model. The overlapped grid technique is employed to catch the flow interference between the two tandem cylinders. It is confirmed that the abrupt numerical change of drag coefficients and the Strouhal number is in good agreement with the previous expe...
