    摘要: In heat generators and burners, it is frequently necessary to realize discontinuous cross-sectional expansions of a flow duct. When the flow (U) passes over the step (10) formed in the wall (8) of the flow duct, coherent lateral separation vortices form which are propagated almost undamped downstream of the step and frequently represent the cause of thermo-acoustic vibrations of high amplitude. In accordance with the invention, vortex-generating elements (20) with a lateral pitch dimension (t) are arranged on a line transverse to the main flow (U) a distance (s) upstream of the step (10). Given an expedient selection of the pitch dimension (t), the lateral coherence of the separation vortex is enduringly destroyed.

    摘要: What is described is a burner system with a premix burner (1), in which is provided at least one vortex generator (2), through which passes an air-containing gaseous main flow (ZL) which flows axially through the premix burner (1) and into which gaseous and/or liquid fuel is injected, downstream of the vortex generator (2), as a secondary flow for generating a fuel/air mixture, and with a combustion chamber (5) which adjoins the premix burner (1) downstream of the latter and has a combustion chamber cross section (C2) which is larger than the flow cross section (C1), delimited by the premix burner (1), directly upstream of the combustion chamber (5). The invention is distinguished in that, between the premix burner (1) and the combustion chamber (5), a flow duct (10) is provided, delimited by side walls which create a gradual transition between the flow cross section (C1) and the combustion chamber cross section (C2), and in that upstream, within and/or downstream of the flow duct (10) is provided at least one flow stall structure (11), by means of which the fuel/air mixture passing through the flow duct (10) is separated locally from the side wall of the flow duct (10).

    摘要: A low pressure drop, highly efficient structured packing comprises sheet material formed into vertical preferably square channels containing vortex generators formed from the sheet material. The channels, while vertically linear, are periodically interrupted by the vortex generators providing tortuous fluid paths along the channels. The thus formed vortex generators form openings between adjacent channels providing fluid communication between and uniform flow within the different channels. The packing can be utilized in fluid mixing or those operations that require multiphase mass transfer, such as absorption or distillation. The addition of a catalyst makes the structure suitable for catalytic distillation. Turbulence is provided the fluids by the tortuous vertical path with low pressure drops transversely and vertically, with optimum liquid holdup.
