This rapidly changing scenario together with availability of high precision and large-scale experimental data has enabled development of high fidelity simulation tools capable of simulating multi-physics multi-scale phenomena.
For the simulation of multi-physics, multi-scale phenomena, it is often advantageous to build a comprehensive system- or process-model from a collection of sub-models, each of them purposely constructed to describe a certain aspect of the overall problem with high accuracy at low computational cost.
Characterizing and controlling nonlinear, multi-scale phenomena are central goals in science and engineering.
A new, integrative form of basic science should provide guidance in the multi-scale phenomena mentioned above and should further provide the tools to develop suitable action intending to control the effects of these developments.
Weinstein is a Professor of Applied Mathematics whose research focus is in partial differential equations, mathematical analysis, dynamical systems and applications to wave and other multi-scale phenomena in inhomogeneous, nonlinear and random media.
However, it has been proven during the recent years that multi-scale phenomena occurring in CFB reactors cannot be accurately reproduced by conventional models.
To take self-consistently into account such multi-scale phenomena, we have developed a new simulation model by directly interlocking the fluid simulation of the magnetohyrdodynamics (MHD) model and the kinetic simulation of the particle-in-cell (PIC) model.
First, we present a new S-HDS-based framework for modeling social diffusion on networks of real-world scale and complexity, enabling these dynamics to be appropriately represented as multi-scale phenomena.
Our aim in participating in the HighResMIP is to investigate multi-scale phenomena including tropical and extratropical cyclones, MJO, tropical waves, convection, and clouds in a seamless manner (see Section 7.2 of Haarsma et al. 2016).
Forty years ago, it was mainly about large-scale phenomena, like inflation and unemployment.
But there's no one right way to model these small-scale phenomena.
