Abstract

A novel method to measure two-component velocity profile simultaneously was developed by using the combined system of a CCD area image sensor and a multi-point laser Doppler velocimetry (LDV). The benefits of this method are shown by pursuing the compact and convenient over the system. Moreover, results of some measurements such as the flow field behind the cylinder shows the reliability of the measurement for turbulence fields. The basic techniques of this method are established and the applicability for the measurement of flow field is shown.
