Normal inverse gaussian PDF of velocity increments in a turbulent heated jet
Abstract eng: Normal Inverse Gaussian law with four parameters on, B, 5 and u is shown to fit very well the experimental pronounced PDF shape with heavy tails at small scales and the Gaussian-like shape for the large scales. The probability density functions of velocity increments are obtained from recorded time series in the self-similarity region of a heated jet. The Reynolds number (Re )- : 105) is sufficiently high to consider the flow as fully turbulent.
