Abstract


  • This study investigates the distribution of turbulence intensities in unsteady non-uniform flows. Yang &

    Chow’s (2008) work was extended to express this distribution based on the relationship between

    Reynolds shear stress and turbulence intensities in unsteady flow. It was found a self-similarity

    relationship between Reynolds shear stress and turbulence intensities in unsteady flow. This

    relationship has been developed as empirical equations based on experimental data available in the

    literature. By applying the self-similarity relationship, good agreements between the measured and

    predicted turbulence intensities have been achieved.
