摘要：This is an elementary study on the application of small-sized exhaust wind power generation to exhausters on the rooftop of high-rise apartment buildings, Here, CFD (Computational Fluid Dynamics) simulation is performed to determine the effect of multi-diffusers for exhaust wind velocity amplification and external wind attraction; the experiments are conducted using miniatures and actual mock-ups. The results of the study are summarized as follows. From the simulation of multi-diffusers for exhaust and ventilation, the wind velocity increased with a greater number of installations of devices, where up to eight was possible and about six was found to be appropriate. In simulation of exhaust effect, an increase in the external wind velocity leads augmentation in the exhauster wind velocity; in particular, it was confirmed that even when there was no exhaust wind (0m/s), there was an exhaust air rise effect due to inflow of the external wind, itself. In the results of experiments with miniatures and mock-ups, the exhauster discharge wind velocity increased due to the external air inflow in the apartment building exhauster, confirming the existence of an exhaust effect. The wind velocity increase rate was greater at the upper part than at the lower part, leading to the prediction that it would be possible to secure over 3m/s, the initial operation wind velocity of small wind power.
