摘要：
In order to evaluate an indoor airflow, which may cause the spread of viruses, it is effective to measure the speed and direction of the airflow using several accurately evaluated anemometers. However, since calibration of anemometers is a time-consuming task, so the authors developed a compact wind tunnel that can evaluate the accuracy of anemometers in a short amount of time. The design concept and performance of the wind tunnel are described by several indices, including averaging time, settling time, spatial distribution, and blockage effect. These results demonstrate the capability of the wind tunnel to evaluate several anemometers in a short measurement time with sufficiently high precision.
