Excitable modes in forced symmetry breaking for a cylindrical container with one rotating endwall
The technical relevance of swirling flows has inspired numerous investigations into the field: swirling flow burners, trailing vortices of delta wings, separators etc. are some of the applications where such research has yielded interesting results. At the same time, geophysics-inspired general swirling flow studies provided much input to this field. A subcategory of swirling flows is that wher...

متن کاملCharacteristics of endwall and sidewall boundary layers in a rotating cylinder with a differentially rotating endwall
The flow in a rotating cylinder driven by the differential rotation of its top endwall is studied by numerically solving the time-dependent axisymmetric Navier–Stokes equations. When the differential rotation is small, the flow is well described in terms of similarity solutions of individual rotating disks of infinite radius. For larger differential rotations, whether the top is co-rotating or ...
متن کاملSteady Vortex Breakdown in Swirling Flow Inside a Closed Container: Numerical Simulations, PIV and LDV Measurements
Numerical simulations and measurements using PIV and LDV have been carried out for steady vortex breakdown inside a closed container. The numerical solution has been employed as a benchmark to assess the capabilities and limitations of the experimental techniques in a difficult flow case involving a double breakdown in the limit of the
متن کاملA review of functionally graded thick cylindrical and conical shells
Thick shells have attracted much attention in recent years as intelligent and functional graded materials because of their unique properties. In this review paper, some critical issues and problems in the development of thick shells made from Functionally graded piezoelectric material (FGPM) are discussed. This review has been conducted on various types of methods which are available for thick ...
