EXPERIMENTAL INVESTIGATION AND HIGH RESOLUTION SIMULATOR OF IN-SITU COMBUSTION PROCESSES

PDF Version Also Available for Download.

Description

Accurate simulation of in-situ combustion processes is computationally very challenging because the spatial and temporal scales over which the combustion process takes place are very small. In this third quarterly report of our DoE funded research, we continue the discussion of the design of a new simulation tool based on an efficient Cartesian Adaptive Mesh Refinement technique that allows much higher grid densities to be used near typical fronts than current simulators. Also, we discuss the possibility of using Strang splitting for handling the large disparity in time-scales between the kinetics and transport in the in-situ combustion process. On the ... continued below

Also, we discuss the possibility of using Strang splitting for handling the large disparity in time-scales between the kinetics and transport in the in-situ combustion process. On the experimental side, we show results of experiments with our scanning electron microscope (SEM) to investigate the sand-clay-salt mixtures that are used for combustion in which we focus on grain sizes, shapes, orientations, characteristic inter-structures, and element analysis. SEM is shown to be a very effective tool in studying these mixtures.
