Advanced coal gasifier designs using large-scale simulations

Low-rank Coal Gasification Studies Using the Psdf Transport Gasifier

The Power Systems Development Facility (PSDF) is an engineering scale demonstration of advanced coal based power systems, including the KBR Transport Gasifier, a hightemperature, high-pressure syngas filtration system, and a gas cleanup unit. Designed to be at a sufficient scale to test advanced power systems and components in an integrated fashion, the PSDF provides data necessary for commerci...

Large-scale Reservoir Simulations Using Pc-clusters

Going through the development more than forty years, the overall water-cut to Daqing Oilfield has almost reached 90%. But there is still considerable residual oil in the place. Reservoir engineers want to know the residual oil spatial distribution and how to dig it. This requires large-scale reservoir simulation within limited time. Enlarged scale and highly expected efficiency need higher tech...

Large Scale Traffic Simulations

SFI WORKING PAPER: 1996-10-080 SFI Working Papers contain accounts of scientific work of the author(s) and do not necessarily represent the views of the Santa Fe Institute. We accept papers intended for publication in peer-reviewed journals or proceedings volumes, but not papers that have already appeared in print. Except for papers by our external faculty, papers must be based on work done at ...

Wri’s Pre‐gasification Treatment of Prb Coals for Improved Advanced Clean Coal Gasifier Design

Large Scale Simulations

In this chapter we will focus on molecular dynamics (MD) simulations with large numbers of atoms (N > 1000). Typically, ab initio or First Principles Molecular Dynamics (FPMD) calculations are performed with smaller clusters of say 100 or fewer atoms. This choice is largely due to limitations in computing resources. The simulation procedure we will explore in this chapter is known as Empirical ...
