DESCRIPTION:Speakers: Peace-Maker Masukume (University of Fort Hare\, Depa
 rtment of Physics)\n\nOptimization of power output from ducted wind turbin
 es has been the focus of many researchers in recent years. However many ha
 ve dwelt much on diffusers than concentrators (nozzles) . Diffusers are ch
 aracterized by flow separation due to deceleration of the fluid and this l
 eads to energy dissipation. On the other hand a concentrator is accompanie
 d by a favourable pressure gradient  which stabilizes the boundary layer a
 nd thus minimizes energy dissipation. This study presents a mathematical m
 odel of a concentrator-Diffuser system which has been developed to optimiz
 e the power output of a low speed wind turbine. Optimization of the inclin
 ation angles of both the concentrator and the diffuser\, ducts exit ratios
   and the reduction in backpressure were found  to augment the mass flow a
 t the rotor due to increased pressure drop and reduction in flow separatio
 n. It is illustrated that Power coefficients (Cp) of about 0.65 are achiev
 able.\n\nhttps://events.saip.org.za/event/7/contributions/4880/
