  • Solution of unsteady, two-dimensional, inviscid flows

    Creator:
    Kuo, Ying-Ming
    Abstract:
    The general theory of characteristics is reviewed for hyperbolic partial differential equations of n independent variables. The application of the theory of characteristics is made to unsteady, two-dimensional, rotational, inviscid flows; unsteady, two-dimensional, irrotational, inviscid flows; and unsteady, axial symmetric, inviscid flows. The characteristic surfaces and the compatibility relations are...

  • Effect of initial conditions on the convergence rate of the energy equation in Couette flow

    Creator:
    Seddigh, Foad
    Abstract:
    Computers are very efficient in handling the problems which deal with iteration. Numerical treatment of the unsteady energy equation is one sort of iteration. The convergence of the unsteady film coefficient, in two dimensional space, to its steady state value has been deduced by comparison of the results of the...

  • Swept time-space domain decomposition on GPUs and heterogeneous computing systems

    Creator:
    Magee, Daniel J.
    Abstract:
    Modern scientific and engineering problems often require simulations with a level of resolution difficult to achieve in reasonable amounts of time—even in effectively parallelized programs. Therefore, applications that exploit high performance computing (HPC) systems have become invaluable in academia and industry over the past two decades. Addressing the questions that...

  • A numerical study of inertial flow features in moderate Reynolds number flow through packed beds of spheres

    Creator:
    Finn, Justin Richard
    Abstract:
    In this work, flow through synthetic arrangements of contacting spheres is studied as a model problem for porous media and packed bed type flows. Direct numerical simulations are performed for moderate pore Reynolds numbers in the range, 10 ≤ Re ≤ 600, where non-linear porescale flow features are known to...
