Operating air velocity的意思|示意

The main factors which had influence on drying rate were found: the operating air velocity, the speed of rotating drum, the temperature of air flow, the shapes and characteristics of materials.

找出影响干燥速率的因素有：操作气速，转鼓转速，热风温度，物料形状，物料特性等。

With numerical simulation method the effect of the airflow pattern created by the air inlet of varying velocity on contaminant concentration and thermal comfort in an operating room was investigated.
