    Direct numerical simulation of turbulent Couette-Poiseuille flow with zero skin friction

    No full text
    The near-wall scaling of mean velocity U(y) is addressed for the case of zero skin friction on one wall of a fully turbulent channel flow. The present DNS results can be added to the evidence in support of the conjecture that U is proportional to √yw in the region just above the wall at which the mean shear dU/dy = 0

    Studies on the Structure of N-Phenyl-Substituted Hexaaza[1(6)] paracyclophane: Synthesis, Electrochemical Properties, And Theoretical Calculation

    No full text
    [[abstract]]The N-phenyl-substituted hexaaza[1(6)]paracyclophane (3, hexamer) has been synthesized successfully in two steps and the noncoplanar conformation was calculated by Gaussian program. The electrochemical properties exhibited lots of interesting results and each overlapping oxidative wave contained two-electron transfer.[[note]]SC
