      <title>NUMERICAL AND EXPERIMENTAL METHODS FOR THE PREDICTION OF FIELD POINT VELOCITIES AROUND PROPELLER BLADES</title>
      <link>https://trid.trb.org/View/82506</link>
      <description><![CDATA[Flow characteristics of a series of NSRDC research propellers (propellers 4381, 4382, 4383, 4498) are experimentally investigated applying Laser-Doppler Anemometer technique. This experimental method is significantly different from conventional ones in providing precise quantitative flow information which would be extremely difficult or impossible to obtain with mechanical measuring probes. The flow characteristics are directly obtained or derived from the measurement of field point velocities. Also, theoretical study has been made for the prediction of field point velocities utilizing numerical lifting-surface theory and the results are compared to those measured. It has been found that the agreement is good or at least theory nicely follows the experimental pattern, which indicates the possibility of a simple correlation between measurement and the present theory.

      <title>DESIGN CONSIDERATIONS FOR A 3-D LASER DOPPLER VELOCIMETER FOR STUDYING GRAVITY WAVES IN SHALLOW WATER</title>
      <link>https://trid.trb.org/View/13964</link>
      <description><![CDATA[A laser velocimeter system using three frequency-modulated light beams and one detector for measurement of the instantaneous velocity vector in reversing flow is considered. An analysis of the scattering and detection processes by means of the Mie and optical mixing theories is outlined. A system proposed for gravity wave studies uses an argon-ion laser and three Bragg cells as a source and a photomultiplier detector of the light backscattered from 0.2 micrometer-diameter spheres, introduced into the flow in a low concentration, and can measure local velocity vectors of magnitude between 0.1 m/sec and 3.0 m/sec, with turbulent fluctuations of 1% or greater intensity.
