The authors have proposed an urban-type wind power generation system, in winch small wind turbines, accommodated within rooftops of urban buildings or houses, absorb wind powers enhanced by the roof configuration. For the purpose, the performance of a simple cross-flow type wind turbine was improved from a viewpoint of the casing flowpath. The efficiency was improved as much as 30% in a relative sense compared to the original simple casing. At the same time, however, the required pressure difference was also increased, which wifi be necessary to be improved hereafter.
