Wake destructive behavior and vortex shedding behind bluff bodies may be controlled by
use of active and passive methods. Computational fluid dynamics, experimental and …

Porous coating on cylinders reduces the aerodynamic noise due to vortex shedding. A key
understanding of how porous media suppress vortex shedding is related to near-field …

Flow around a circular cylinder is ubiquitous in nature and industrial applications. In marine,
coastal and bridge engineering, undesirable vortex-induced vibrations (VIVs) of structural …

The flow behavior around a vertical circular cylinder placed in shallow water was controlled
by a splitter plate inserted at various locations downstream of the cylinder. The splitter plate …

The flow and heat transfer topology of an isothermal cylinder (diameter D) in the wake of
another smaller (diameter d) cylinder is numerically investigated for a spacing ratio of L/d …

This work aims to provide a systematic experimental study on the wake of two tandem
cylinders of unequal diameters. The fluid dynamics around a circular cylinder of diameter …

The effect of the installation of a circular cylinder upstream of the returning turbine blade on
the performance of the Savonius wind turbine was studied experimentally. The experiments …

The Savonius drag-type wind turbine suffers from poor efficiency due to the adverse
negative torques on the returning blades when they rotate against incoming flows. It was …

Studies on the flow-induced vibration (FIV) of tandem unequal-diameter flexible cylinders in
a broad gap ratio range are scarce. To reveal the effect of the gap ratio on and characterize …

This paper presents a detailed investigation of Strouhal numbers, forces and flow structures
in the wake of two tandem cylinders of different diameters. While the downstream cylinder …
