A discrete vortex method is implemented with a hybrid control technique of vortex shedding
to solve the problem of the two-dimensional flow past a slightly rough circular cylinder in the …

Numerical tests at high Reynolds number flows were taken on circular cylinder placed near
and parallel to a moving ground. A moving ground running at the same speed as the free …

A new technique for two-dimensional vortex methods is presented. The vorticity field is
discretized and represented by vortex blobs. Viscosity and roughness are incorporated into …

Turbulent flows around bluff bodies are present in a large number of aeronautical, civil,
mechanical, naval and oceanic engineering problems and still need comprehension. This …

This paper describes the development of a Lagrangian roughness model to simulate the
effect of surface roughness in two-dimensional flow on the proximity of the cylinder, at high …

A purely Lagrangian vortex method is employed to investigate turbulent flows past a rough
circular cylinder under moving wall effect at large-gap regime, namely h*/d*= 0.45 and 0.80 …

Brazil has one of the richest river basins in the world and an energy matrix based mostly on
hydroelectric power. Current national policy is increasingly promoting renewable sources …

The objective of this paper is to study the vortex shedding from a circular cylinder near a
moving ground; this is done using the Vortex Method. A moving ground has been widely …

This paper concerns the numerical simulation of the flow around an oscillating circular
cylinder, which moves with constant velocity in a quiescent Newtonian fluid with constant …

As one of the typical negative factors affecting the vortex structure and flow characteristics of
hydraulic machinery, the TLV has a non-negligible impact on the energy performance. In …
