A flow acceleration system (FAS) comprised of a compact diffuser with flange at the exit was designed, fabricated and retrofitted with a commercially available micro wind turbine. After design and laboratory experiments, pilot testing at the rooftop of a building in a typical urban site at Dhaka, Bangladesh was conducted to compare the power generation performance with a bare turbine of same specifications. The obtained data indicate the augmentation in power and de-escalation in cut-in speed, suggesting that the FAS augmented wind turbine can be an effective solution for power generation in the context of urban areas in Bangladesh.
