A novel ventilation mode was introduced and investigated by a series of experiments under isotherm condition, focusing on elucidating the airflow patterns and characteristics associated with this mode. Semi-empirical equations were derived to effectively describe the jet characteristics.

The primary characteristic parameters of the jet include the maximum velocity um, the jet spread rate, and the non-dimensional velocity profiles.

In this section, these parameters will be comprehensively analyzed and discussed to gain a better understanding of the proposed air supply method.

The adaptive attachment ventilation with deflectors (AAVD) offers a customized air supply method for variable control zones. In essence, AAVD combines the principles of attachment ventilation and stratified ventilation.
