“…They observed that for high values of streaming Reynolds number, the axial streaming velocity starts to depart from the theoretical slow streaming. Peng and Hsu [83] studied the flow in Stokes layers above an oscillating flat plate and inside an oscillating narrow channel using LDV for various Reynolds numbers in the laminar regime. They observed a good agreement between the experimental results and the theoretical predictions for a range of velocities and phases.…”

Velocity measurement in pulsating flows is more difficult than that in steady flows. One problem follows from the necessity to synchronize the measuring instrument with the characteristic of the flow which is not required for steady-flow measurements. The second challenge is high frequency response of the measuring device which is required for high frequency pulsating flow measurements. Because of development of more advanced measurement devices, there has recently been a growing interest in pulsating velocity measurement and the number of papers in this field has increased significantly in recent years. In this review, the most frequently-used advanced techniques for velocity measurement in pulsating flows are surveyed. The characteristics of different pulsating flows as well as the advantages and limitations of the developed techniques are discussed.

“…Laser Doppler velocimetry (LDV) is widely used in blood flow velocity measurements and is well established as a method for analyzing particle movements at a single point in a fluid based on the Doppler effect [9][10][11][12][13][14]. However, LDV requires a significant measurement time in order to delineate a two-dimensional (2D) or three-dimensional (3D) flow field.…”

“…Laser Doppler velocimetry has been used to measure the temporal change in the velocity of flowing fluids and fluctuations for the investigation of fluid flow. [14][15][16][17][18] However, in recent years, more advanced methods are required in order to investigate topics such as unsteady three-dimensional turbulent flow, micro-scale flow in electronics devices, and flow in biochemical systems. [19][20][21][22][23][24][25][26] We have previously developed a laser Doppler velocimeter (LDV) that is capable of measuring the velocity at multiple points along a straight line, and is based on a conventional single-point LDV.…”

A laser Doppler velocimeter (LDV) has been developed that is capable of performing two-dimensional (2D) cross-sectional measurements. It employs two horizontal laser light sheets that intersect at an angle of 13.3°. Since the intersection region is thin, it can be used to approximately determine the 2D flow field. An 8 ' 8 array of optical fibers is used to simultaneously measure Doppler frequencies at 64 points. Experiments were conducted to assess the performance of the LDV, and it was found to be capable of obtaining spatial and temporal velocity information at multiple points in a flow field. The technique is fast, noninvasive, and accurate over long sampling periods. Furthermore, its applicability to an actual flow field was confirmed by measuring the temporal velocity distribution of a pulsatile flow in a rectangular flow channel with an obstruction. The proposed device is thus a useful, compact optical instrument for conducting simultaneous 2D cross-sectional multipoint measurements.
