| Abstract |
The existing cooling system can not satisfied the human thermal need as compared to the natural breeze in country side where located near mountains and river side. Why don't we feel comfortable? This difference can be described by the fluctuation characteristics of natural wind. The natural wind fluctuates all the time in all directions and we can not recognize its behaviors. If the fluctuation characteristics of natural wind would be generated with existing cooling system, it could be a comfortable wind for us. In this study, the characteristics of natural wind will be analyzed through chaotic analyzing methods and will be compared to the mechanical wind. In this paper, the field measurement for natural wind which accomplished at near mountain in summer will be reported. Moreover the characteristics of mechanical wind will be analyze through laboratory experiment. Finally, the Chaotic Phenomena of Natural Wind and Mechanical Wind will be described. |
