[1] To determine the efficacy of turbulence in the solar wind, the amount of mixing of the solar wind plasma is quantified. If magnetohydrodynamic turbulence in the solar wind acts as does Navier-Stokes turbulence, the chunk mixture of scalar quantities in the solar wind plasma should evolve with time. In particular, (1) the sizes of plasma chunks should decrease with distance from the Sun owin...

This paper presents a multi scale color coding technique which enhances the visualization of scalar fields along integration lines in vector fields. In particular, this multi scale technique enables one to see detailed variations in selected small ranges of the scalar field while at the same time allowing one to observe the entire range of values of the scalar field. This type of visualization,...

a r t i c l e i n f o Keywords: Mixing performance DEM MGMMI Blade-rake angle Bladed mixers This study focuses on the understanding of flow over a single blade and its impact on powder mixing. The Discrete or Distinct Element Method (DEM) is used and the flow of a single blade through a bed of a binary particle mixture is studied. Mixing performance with respect to a blade-rake angle and partic...

A new strategy to formulate transportation fuels surrogates using model predictions of gas-phase combustion targets is explored. Given a selection of individual fuel components, a multi-component chemical mechanism describing their oxidation kinetics, and a database of experimental measurements for key combustion quantities such as ignition delay times and laminar burning velocities, the optima...

This paper follows the evolution in understanding of the multiple mapping monditioning (MMC) approach for turbulent combustion and reviews different implementations of MMC models. As the MMC name suggests, the original version represents a consistent combination of CMC-type conditional equations (conditional moment closure) and generalised mapping closure. It seems that the strength of the MMC ...
