CMT-Bone — A Proxy Application for Compressible Multiphase Turbulent Flows

CMT-bone is a proxy app of CMT-nek, which is a solver of the compressible Navier-Stokes equations for multiphase flows being developed at University of Florida. While the objective of CMT-nek is to perform high fidelity, predictive simulations of particle laden explosively dispersed turbulent flows, the goal of CMT-bone is to mimic the computational behavior of CMT-nek in terms of operation counts, memory access patterns for data and performance characteristics of hardware devices (memory, cache, floating point unit, etc.). CMT-bone, as a proxy app, has a tremendous potential to be an important benchmark to realize tradeoffs in HPC software, hardware, and algorithm design aspart of the co-design process.

Mixing at a sediment concentration interface in turbulent open channel flow

In this work we address the role of turbulence on mixing of clear layer of fluid with sediment-laden layer of fluid at a sediment concentration interface. This process can be conceived as the entrainment of sediment-free fluid into the sediment-laden layer, or alternatively, as the transport of sediment into the top sediment-free flow. This process is governed by four parameters—Reynolds number of the flow
