Linear and Secondary Instabilities in Incompressible Axisymmetric Boundary Layers: Effect of Transverse Curvature By N.V INODand RAMA GOVINDARAJAN

The stability of the incompressible boundary layer in the axial flow past a cylinder has not been studied a great deal. The laminar flow is shown here to be always stable at high transverse curvatures to linear as well as secondary disturbances. At low levels of curvature, the first instability is delayed, but several non-axisymmetric modes are simultaneously unstable, which could lead to a dif...

Secondary Instabilities in Incompressible Axisymmetric Boundary Layers: Effect of Transverse Curvature

The incompressible boundary layer in the axial flow past a cylinder has been shown Tutty et. al.([11]) to be stabler than a two-dimensional boundary layer, with the helical mode being the least stable. In this paper the secondary instability of this flow is studied. The laminar flow is shown here to be always stable at high transverse curvatures to secondary disturbances, which, together with a...

Impinging laminar jets at moderate Reynolds numbers and separation distances.

An experimental and numerical study of impinging, incompressible, axisymmetric, laminar jets is described, where the jet axis of symmetry is aligned normal to the wall. Particle streak velocimetry (PSV) is used to measure axial velocities along the centerline of the flow field. The jet-nozzle pressure drop is measured simultaneously and determines the Bernoulli velocity. The flow field is simul...

Numerical Simulation of the Incompressible Laminar Flow Over a Square Cylinder

Simulation of fluid flow over a square cylinder can be performed in order to understand the physics of the flow over bluff bodies. In the current study, incompressible laminar flow over a confined square cylinder, with variable blockage factor has been simulated numerically, using computational fluid dynamics (CFD). The focus has been on vortex-induced vibration (VIV) of the cylinder. Vorticity...
