Aerodynamics of a Cyclone Heat Exchanger

详细

The results of an experimental and analytical study of the effect of gas flow rate (Reynolds number) on the pressure distribution, the tension of surface friction, and the characteristics of the boundary layer on the heat-transfer pipe surface of a cyclone heat exchanger offset from the aerodynamic axis of a highly turbulent swirling flow are provided and analyzed. It was found that the decrease of the Reynolds number below the value that defines the boundary of the cyclonic flow self-similarity changes the flow conditions around the pipe surface, the position of the critical points, the dimensions of the characteristic zones, and the flow regime of the boundary layer in its frontal part.
