Bluff–Body Flow and Fluid–Structure Interactions

Dear Colleagues,

Flow-induced vibration (FIV) of cylindrical structures is of both fundamental and practical significance. Industrial and engineering architectures are often the combinations of multiple cylindrical structures, such as offshore platforms, risers, undersea pipelines, cables of cable-stayed bridges, groups of chimney stacks, tubes in heat exchangers, transmission line bundles, adjacent skyscrapers, etc. While the wake of a single structure is very complex, the flow interference between multiple structures, making the wake more complex, leads to high fluctuating forces, structural vibrations, acoustic noise, or resonance, which in some cases can trigger failure. Both experimental and numerical investigations have improved our understanding of flow-induced vibrations and provided some effective frameworks to suppress vibrations.

The flow and heat transfer topologies around isothermal circular and square cylinders have received a great deal of attention in many practical engineering applications, such as electronic-chip cooling systems (processors and power chips) and turbine blade cooling systems. Particularly, due to the technological developments of electronic components, the cooling of chips on board is a fundamental issue to increase the service life or to avoid overheating. Design optimization and miniaturization of electronics components are always demanded in terms of heat transfer enhancement.

Energy can be harnessed continuously from horizontal currents by employing alternating lift force technologies. Fluid flow over structures (e.g., foils, circular, square, rectangular cylinders) produces an alternating lift force due to complex fluid–structure interactions. The lift force generates vibration of the structure, while flow-induced vibration involves different phenomena such as vortex-induced and galloping vibrations. The kinetic energy of a violently vibrating structure can be converted into electricity, which can help to run a generator.

This Special Issue encompasses advances in bluff-body flow, fluid–structure interactions, heat transfer from bluff bodies, and wind/ocean energy in the fields of mechanical, civil, aerospace, ocean, chemical, energy, physics, and mathematics research. Research articles, review articles, and short communications are welcomed. Research techniques can be experimental, theoretical, computational, or a combination thereof. Papers should be academically excellent and original and include novel applications, approaches, and fundamental outcomes.
