Control of flow past a circular cylinder using rotating control rod is investigated by conducting two-dimensional numerical simulations with Reynolds number 200, rod-to-cylinder diameter ratio 0.2, gap position angles the between 0° and 180°, rotation rates −7 7. The rate positive if rotates in anticlockwise direction. aim this paper to discover effects angle on control. If placed at side (posi...

The momentum equation in the kinematic wave model is a power-law equation with two parameters. These parameters, which relate the discharge to the flow area, are commonly derived using Manning’s equation. In general, the values of these parameters depend on the flow depth except for some special cross sections. In this paper, improved estimates of the kinematic wave parameters for circular chan...

The problem of generation self-sustained oscillations in the flow past a circular cylinder with splitter plate is solved numerically. We investigate both transient process and steady periodic vortex shedding behind cylinder. evolution vorticity field shown for various length plate. It demonstrated that oriented along direction significantly reduces forces applied to With increasing average drag...
