Simulation of proppant transport in slickwater with DNS-derived drag correlations
This dissertation is developed to address a need of multiphase flow models for proppant transport: problem-relevant drag correlations. This dissertation consists of small-scale simulations by direct numerical simulations (DNS) and larger, fracture-scale simulations by MFIX (Multiphase Flow with Interaction eXchange). DNS was employed to study the influences of several dimensionless numbers, namely the Reynolds number of cross flow, 〖Re〗_x, the Archimedes number, Ar, consisting of gravity, density difference, slickwater viscosity, and proppant size, the density of proppants relative to that of ...
