Mechanisms and enhancement of CO2 condensation heat transfer
Heat transfer characteristics of CO2 condensation on common heat exchanger materials, method development and experimental results
Understanding condensation of CO2 is essential for e.g designing compact heat exchangers or processes involved in Carbon Capture and Storage. However, a consistent experimental campaign for condensation of CO2 on common materials is lacking. In this work, we present an experimental method and an...
Condensation heat transfer of CO2 on Cu based hierarchical and nanostructured surfaces
Phase-change processes such as condensation are efficient means of heat transfer. However, condensation is also an energy-intensive process and extensive research is conducted to increase the heat transfer efficiency. Increasing the effective heat transfer area in terms of surface structures on...
A combined fluid-dynamic and thermodynamic model to predict the onset of rapid phase transition in LNG spills
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 combined fluid-dynamic and thermodynamic model to predict the onset of rapid phase transitions in LNG spills
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...
