Summary on Grant Application Form |
In most shear flows the onset of turbulence occurs as a result of vortex or wave instabilities. Recently Hall & Papageorgiou (1999) discovered that certain types of time periodic flows become chaotic as a direct consequence of their unsteadiness. Such a possibility occurs at all amplitudes but a particularly interesting case occurs when the forcing is of low amplitude and steady streaming flows occur. This scenario will be developed in a wide variety of fluid flows of practical importance. The mechanism investigated will be relevant to applications as varied as the damping of offshore structures, mixing devices and blood flow.
