The paper presents the discovery – by means of wind tunnel tests and with the support of CFD simulations – of a new aerodynamic phenomenon around circular cylinders. It is a new type of bistable flow, which is induced by the presence of ring beams along the height of a cylinder with a free-end. This investigation was performed within a research project on Solar Updraft Towers, i.e. ultra-high structures (1 km or even more) to produce renewable energy. They convert solar radiation into electric… CONTINUE READING
