Schlieren measurement of axisymmetric internal wave amplitudes

  title={Schlieren measurement of axisymmetric internal wave amplitudes},
  author={K. Onu and Morris R. Flynn and B. R. Sutherland},
‘Synthetic schlieren’’, which has been used to measure the amplitude of two-dimensional internal wave beams generated from an oscillating cylinder, is adapted to analyze axisymmetric internal waves generated by an oscillating sphere. This nonintrusive technique uses elementary inverse tomographic methods to measure the amplitude of the conical-structured wave beams everywhere in space and time. We compare the results with in situ probe measurements, and we examine the structure of the wave… CONTINUE READING
