New Development of Airflow Fluent Characteristics and Its Impact on Human Thermal Comfort
The dynamization of airflow is an important way to ameliorate indoor thermal environment.As the acceptable dynamic airflow,the study on dynamic characteristics of natural wind and the comparison between natural and mechanical wind will be meaningful for people to ameliorate indoor thermal environment.The fluctuant characteristics of natural wind and mechanical wind are obviously different.However,the fluctuant characteristics of mechanical wind can be changed to those of natural wind in some conditions. With the development of turbulence statistical theory,chaos and fractal theory,researchers began to use these theories to describe the structural characteristics of fluctuating airflow in different environments or from different generating sources.The current achievements of the studies on airflow fluctuation and thermal environment are reviewed in the paper from two aspects: the effect of airflow fluctuation on thermal comfort and the physical structure of airflow fluctuation.This paper reviews these achievements first,followed by a summary of studies conducted at Tsinghua University.
