  • Segregation of granular Binary Mixtures by a ratchet mechanism.
    Physical Review E, 2002
    Co-Authors: Zénó Farkas, Ferenc Szalai, Dietrich E. Wolf, Tamás Vicsek
    Abstract:

    We report on a segregation scheme for granular Binary Mixtures, where the segregation is performed by a ratchet mechanism realized by a vertically shaken asymmetric sawtooth-shaped base in a quasi-two-dimensional box. We have studied this system by computer simulations and found that most Binary Mixtures can be segregated using an appropriately chosen ratchet, even when the particles in the two components have the same size, and differ only in their normal restitution coefficient or friction coefficient. These results suggest that the components of otherwise non-segregating granular Mixtures may be separated using our method.Comment: revtex, 4 pages, 4 figures, submitte

  • bubble point measurements of n butane n octane and n butane n nonane Binary Mixtures
    Journal of Chemical & Engineering Data, 2015
    Co-Authors: Elisabeth Mansfield, Stephanie L Outcal
    Abstract:

    Mixtures of small gaseous hydrocarbons with longer chain hydrocarbons are of interest to the natural gas industry as well as other industries in which separations are critical. In particular, Binary Mixtures of n-nonane are of interest, because n-nonane was recently incorporated into the GERG-2008 equation of state, but there is little experimental vapor–liquid equilibrium (VLE) data available to support the equation. The bubble-point pressures of four compositions of each of the Binary Mixtures n-butane + n-octane and n-butane + n-nonane were measured over the temperature range of 270 to 370 K. The data and the expanded uncertainty (at a 95 % confidence level, k = 2) of each point are reported. Additionally, the data are compared to existing literature data for the n-butane + n-octane and the GERG-2008 equation for both systems. This is the first report of vapor–liquid equilibrium measurements on n-butane + n-nonane Binary Mixtures.

  • bubble point measurements of eight Binary Mixtures for organic rankine cycle applications
    Journal of Chemical & Engineering Data, 2013
    Co-Authors: Stephanie L Outcal, Eric W Lemmo
    Abstract:

    The bubble-point pressures of two compositions of each of eight Binary Mixtures have been measured over a temperature range of 270 K to 380 K. Six of the Mixtures included pentane, which was mixed with 1,1,1,3,3-pentafluoropropane (R-245fa); methyl perfluoropropyl ether (R-E347mcc); 1,1,1,2,2,4,5,5,5-nonafluoro-4-(trifluoromethyl)-3-pentanone; 1,1-dichloro-1-fluoroethane (R-141b); trans-1,3,3,3-tetrafluoropropene (R-1234ze(E)); and dimethyl ether. The two remaining Binary Mixtures were 1,1,1,2,2,4,5,5,5-nonafluoro-4-(trifluoromethyl)-3-pentanone + methyl perfluoropropyl ether (R-E347mcc) and butane + R-245fa. Interaction parameters for a Helmholtz energy mixture model were fitted for each mixture. Bubble-point data are reported as well as mixture model parameters, along with deviations of the data from their respective equations. These Mixtures are of interest as working fluids in organic Rankine power cycles.
