Coupled CO2-well-reservoir simulation using a partitioned approach: effect of reservoir properties on well dynamics
We present a model framework for dynamic simulation of the flow of (Formula presented.) and other components in an injection well coupled with a near-well reservoir. With a partitioned approach, we employ numerical methods adapted to the governing equations in each domain. In both well and reservoir...
A multiscale porous–resolved methodology for efficient simulation of heat and fluid transport in complex geometries, with application to electric power transformers
The numerical simulation of fluid flow through a complex geometry with heat transfer is of strong interest for many applications, such as oil-filled power transformers. A fundamental challenge here is that high resolution is necessary to resolve the fluid flow phenomena, but this makes simulation of...

A detailed review on CO2 two-phase ejector flow modeling
Ejector-equipped vapor-compression systems for refrigeration and cooling, relying solely on (R744) as a natural working fluid, are perceived to be an eco-friendly and highly efficient solution for many applications. However, the complexity of two-phase ejector flows makes it very challenging to...
