  • energy dissipation rates of newtonian and non newtonian fluids in a stirred vessel
    Chemical Engineering & Technology, 2014
    Co-Authors: Xu Wang, Xin Feng, Chao Yang, Zai-sha Mao
    Abstract:

    Energy dissipation rates of water and glycerol as Newtonian fluids and carboxyl methyl carbonate solution as non-Newtonian fluid in a stirred vessel are investigated by 2D particle image velocimetry and compared. Mean Velocity profiles reflect the Reynolds (Re) number similarity of two flow fields with different rheological properties, but the root mean square Velocity profiles differ in rheology at the same Re-number. Energy dissipation rates are estimated by direct calculation of fluctuating Velocity gradients. The varying energy dissipation rates of Newtonian and non-Newtonian fluids result from the difference in fluid rheology and apparent viscosity distribution which decides largely the flow pattern, circulation intensity, and rate of turbulence generation.

  • SDSS-IV MaNGA: stellar population correlates with stellar root-Mean-Square Velocity V rms gradients or total-density-profile slopes at fixed effective Velocity dispersion σ e
    Monthly Notices of the Royal Astronomical Society, 2020
    Co-Authors: Michele Cappellari, Shude Mao
    Abstract:

    ABSTRACT Galaxy properties are known to correlate most tightly with the galaxy effective stellar Velocity dispersion σe. Here, we look for additional trends at fixed σe using 1339 galaxies (M* ≳ 6 × 109 M⊙) with different morphologies in the MaNGA (DR14) sample with integral-field spectroscopy data. We focus on the gradients (γrms ≡ σ(Re/4)/σe) of the stellar root-Mean-Square Velocity ($V_{\rm rms} \equiv \sqrt{V^2 + \sigma ^2}$), which we show traces the total mass density gradient γtot derived from dynamical models and, more weakly, the bulge fraction. We confirm that γrms increases with σe, age, and metallicity. We additionally find that these correlations still exist at fixed σe, where galaxies with larger γrms are found to be older and more metal-rich. It means that mass density gradients contain information of the stellar population which is not fully accounted for by σe. This result puts an extra constraint on our understanding of galaxy quenching. We compare our results with galaxies in the IllustrisTNG hydrodynamical simulations and find that, at fixed σe, similar trends exist with age, the bulge fraction, and the total mass density slope but, unlike observations, no correlation with metallicity can be detected in the simulations.
