Abstract
In order to detect the point of boundary layer separation, a measuring method based on the change of surface pressure distribution is discussed, and a design of flexible substrate based micro pressure sensor array is also proposed. This array can achieve real-time online measuring while meeting the measuring requirement of non-planar surface. The paper studies a determination method used to detect separation point and proves its validity through a flow simulation of 2D column. The introduction of micro pressure sensor array expands ways detecting boundary layer separation point.
