| This thesis examined the influence of relative permeability, constant concentration contaminant sources, multi-component gases, and latent heat effects on electrical resistance heating (ERH). An existing electro-thermal model coupled to a macroscopic invasion percolation model (ETM-MIP) was modified for the study. Simulations results showed that ERH may generate enough gas to significantly reduce aqueous phase relative permeability, thereby significantly reducing aqueous phase velocity and mass transport. When a constant concentration source zone is simulated, gas generation persists and gas bubbles travel much further with greater redistribution of contaminant. By including dissolved nitrogen and oxygen as background components, multi-component partitioning increases, resulting in more gas bubble generation. Finally, by taking into account latent heat, the model is able to simulate energy associated with vaporization, and constant co-boiling temperature plateaus are predicted in contaminant source zones. |
