LoginA dynamic airflow compared with a steady airflow seems to intensify people's cold sensation . One possible reason is a physical factor - the enhancement of heat transfer - : this paper focused on that first possibiity, but the experimental results indicate that there is no increase of the heat transfer coefficient under sinusoidal airflow compared with a steady airfllow with the same mean velocity.
The conclusion is that a second factor - physiological and psychological - the alarm signal from thermoreceptors could be the reason for the intensifying of people 's cold sensation.
