This work aims to establish a fast and robust mechanistic model framework for predicting phase fraction profiles in bubbly flows. The main motivation is that the associated closure laws can in the future be used as a basis for a more general gas entrainment model in multiphase flows. Two-phase gas...

Fe–26Si–9B alloy is a promising high temperature phase change material (HTPCM), due to its high heat of fusion, small volumetric change, abundance, and low cost. Additionally, graphite has been identified as a promising candidate for use as a container material for this alloy. In this study, the...

Hydrocarbon production driven by water flooding is energy-intensive. This paper presents well-placement and joint well-placement-and-control optimization studies with objective function taking into account emissions, pursuing more energy-efficient water flooding. To assess the effect of emission...

The growing concern for the emission of greenhouse gases and several recent international regulations promote the introduction of innovative solutions aiming at the reduction of pollutant production in all human activities, including maritime transportation. Phasing out conventional marine gas oil...

Flexible graphite (FG) with ρ = 1 g/cm3 density is a type of highly porous and anisotropic graphite, mainly used for gaskets and sealing applications, but also suitable for energy absorption, such as in the beam dumping devices of the Large Hadron Collider (see Heredia 2021 [1]). Knowledge of its...

Carbon Capture and Storage (CCS) is among the main available options to cut CO₂ emissions from the industry and energy production sectors, but the high costs of current CCS technology still limit their large-scale applicability. For this reason, there is increasing interest in alternative absorbents...

The effect of raw materials on the temperature development and prereduction behavior of Comilog and Nchwaning manganese ores (3.33–4.00 mm or 11.20–15.00 mm) were investigated in a CO-CO2 atmosphere. Experiments were conducted at a heating rate of 6 °C/min from room temperature to 1000 °C where the...

Carbon capture, transport, and storage (CCTS) enables the decarbonization of industrial emitters. CCTS is regarded as crucial in reaching net-zero emission targets but currently stands far behind the required scale. CCTS deployment for point sources may be accelerated by CCTS chains relying on...
