Analysis on the Characteristics of Mechanical and Natural Wind Field
Abstract:By testing the flow field characteristics of three types of fans, the characteristics of physical parameters such as instantaneous velocity, turbulence degree, pulsation frequency and β value are compared and analyzed, and the main influencing factors of airflow characteristics of different types of fans are clarified. And through the comparison and analysis of the outdoor natural wind test, the dynamic characteristics of the fan mechanical wind and the natural wind are verified, which provides the research foundation and data support for the human body thermal comfort experiment suitable wind speed and fan comfort wind manufacturing and product development.
