摘要

The fluctuation characteristics of airflow have impacts on the thermal comfort. Three different kinds of mechanical airflows were tested and analyzed in the paper. The results show that the characteristic parameters of the mechanical airflow, such as power spectrum, change regularly with the distance from the fan supply terminal. The phenomenon is summarized and explained in the paper.
