Being an experimental study of CFD simulation and air current measurement for application of PSWP generators on the rooftop of apartment buildings, this research developed urban wind power resources based on the wind speed data for the recent decade by Daegu’s Branch Office of Meteorology and designed and manufactured a PSWP module according to the current status of arrangements and rooftop parapets of apartment buildings and CFD simulation. It developed a method to optimize the efficiency of PSWP generators by creating the same outside air condition as the rooftop of apartment buildings and measuring air currents according to outside air velocity, wind direction change and PSWP installation condition. The results of the experiment according to outside air velocity, parapet distance, the percentage of perforated sheet, angle of guide vane, extension height of parapet and generator arrangement are as follows: For variable installations of generators for changes in outside air environment, outside air velocity over 5.0m/s and parapet, a distance of less than 0.5m is required to secure operating wind speed more than 3.0m/s; if the distance is over 0.5m, the height of parapet needs to be increased. When it comes to wind speed by wind direction, frontal winds are more advantageous than crosswinds; accordingly, as for the percentage of perforated sheet, an enclosed structure is favorable. For wind speed by guide vane angle, a horizontal angle to the wind direction (0°) is better. Also, the highest extension of parapet support, 0.45m, is more advantageous. For a single arrangement of a generator, the top of the parapet is effective, while the top of the front and the middle of the back are the most favorable for a double arrangement. |
