tunnel floor

Due to the existence of boundary layer on a test floor, the characteristics of experimental flow field is different from the real situation, which leads to the inaccuracy of testing data. Therefore, the control of boundary layer is essential to a wind tunnel test floor.

由于地板附面层的存在，实验流场特征与真实情况存在差异，对实验结果的准确性产生一定影响，因而附面层的控制对风洞试验地板至关重要。
