A pulsed Coandă-effect reciprocating wind energy generator

Wind Energy Generation by Forced Vortex Shedding

“…Therefore, to calculate system efficiency, evaluation of the power invested in applying the ASB and the power extracted from the flow is required. The CoRe device [24][25] [26] is comprised of a sting-mounted cylinder on a pivot that is counterbalanced by tension springs which has one degree of freedom (1-DOF), free to rotate about a pivot. The system's center of mass is located above the rotation axis and it is only the springs that hold it balanced.…”

“…It is important to note that for an ASB energy harvesting device, the phase angle can be 32 externally imposed because the input blowing pulses can be arbitrarily input. The damping ratio of the system  is based on value from previous work [24]. In order not to violate the linear assumptions,  was changed as function of C  and r V such that the cylinder velocity to the wind speed ratio / 0.1 AU   …”

“…The system was subsequently loaded with an air-pump and produced net positive power [23]. More recently, our group developed the so-called Coandă-based Reciprocating (CoRe) system [24] where alternating slot blowing at 0.05 e St  was applied alternately on the sides of a circular cylinder, for the purpose of developing a wind energy device (see Video). This concept is particularly effective as a high-torque device [25] that was demonstrated as a means of driving piston pumps for water desalination [26].…”

“…Другим известным направлением примения плохообтекаемых тел является микроэлектроника [25]. Широко плохообтекаемые тела используются в возобновляемых источниках энергии, в частности для получения кинетической энергии в ветровых турбинах [26][27][28].…”
