Rapid mixing of liquids is important for most microfluidic applications. However, mixing is slow in conventional micromixers, because, in the absence of turbulence, mixing here occurs by molecular diffusion. Recent experiments show that mixing can be enhanced by generating transient flow resulting in chaotic advection. While these are planar microchannels, here we show that three-dimensional or...

The properties of ρ-mesons at finite temperature (T ) are examined with an effective chiral lagrangian in which vector and axial-vector mesons are included as massive Yang-Mills fields of the chiral symmetry. It is shown that, at T 2 order, the effective mass is not changed but only the mixing effect in vector and axial-vector correlator appears. PACS numbers : 25.75+r, 11.10.Wx, 11.30.Rd Types...

Chiral symmetry restoration in a dense medium is to some extent a consequence of the nuclear pion cloud. These pions induce a mixing of the axial and vector current contributions in the axial and vector cor-relators. We discuss their influence on hadron masses and investigate the signal produced by the remaining contribution associated with chi-ral symmetry restoration. Using the quark-meson co...

We define maximal CP nonconservation as occurring when a unique convention-independent parameter t, a quartic function of the Kobayashi-Maskawa matrix V, is maximized. The maximum value is much greater than the experimental upper limit, and so the observed CP nonconservation is much less than maximal. Maximal CP nonconservation corresponds to maximum mixing of the quark generations, just as max...

In this study, an Eulerian-Eulerian multi-fluid model (MFM) was used to simulate the segregation pattern of a conical fluidized bed containing ternary mixtures of equidensity TiO2‌ particles. Experimental 'freeze–sieving' method was employed to determine the axial mass fraction profiles of the different-sized particles, and validate the simulation results. The profiles of mass fraction for larg...

Mixing tanks equipped with mechanical stirrer are broadly applied in chemical and petrochemical industries, due to their variety of industrial process requirements. In this study, helical single blade mixer was designed applying CATIA and then mixing of fluid and solid particles, in a tank with this agitator was examined by OpenFOAM. For velocity distribution in the mixing tank, continuity, mom...
