Stratocumulus transitions in present-day and future climate

Clouds have a strong net cooling effect on our planet, as they reflect a large part of the incident solar radiation. To be able to make accurate forecasts of the global climate, cloudiness should therefore be correctly represented by climate models. Currently, however there are large differences in the forecasted temperature increase among...

Wave Simulation in Truncated Domains for Offshore Applications

<Subject and main objective> There is a desire to assess extreme wave loads on offshore structures like Floating Production, Storage and Offloading (FPSO) vessels, either for design, or for evaluation when circumstances near the structure change. Design formulae for extreme wave loads are scarce and have limited validity for specific structures....

Nonisothermal flows of vicsoelastic fluids. Thermodynamics, analysis and numerical simulation.

Computational Modeling of Hydro-Electro-Mechanical Flow During CO2 Geosequestration

CO2 geo-sequestration (CGS) is considered to be a feasible technology for reducing the amount of CO2 emission into the atmosphere. Selection of an appropriate reservoir is vital and requires appropriate knowledge of the involved phenomena and processes. In a CO2 geo-sequestration process, carbon dioxide goes through mainly four storage (trapping...

Large-eddy simulation of a turbulent jet

Direct and Large Eddy Simulation of Turbulent Flow in a Cylindrical Pipe Geometry

Initial porosity of random packing: Computer simulation of grain rearrangement

The initial porosity of clastic sediments is poorly defined. In spite of this, it is an important parameter in many models that describe the diagenetic processes taking place during the burial of sediments and which are responsible for the transition from sand to sandstone. Diagenetic models are of importance to predict the sub-seismic...

Mould filling simulations during powder injection moulding

Powder injection moulding (PIM) is a versatile technology capable of producing complex and near net shape parts. Significant help in optimisation of the PIM process can be obtained from the numerical simulation. To obtain realistic numerical results it is necessary to fulfil certain conditions. The material properties should be correctly...

Simulation of foam in Enhanced Oil Recovery (EOR) and Carbon Capture and Storage (CCS) applications

Foam is an agglomeration of gas bubbles separated from each other by thin liquid films. Foam injection has been proved to be an efficient way to increase sweep efficiency in gas-injection enhanced-oil-recovery (EOR) processes or enlarge the storage space for trapping of CO2 in aquifers. Numerical simulation, an important tool developed by...

Experimental Study and Numerical Simulation of the Reaction Process and Microstructure Formation of Alkali-Activated Materials

Alkali-activated materials (AAMs) show promising potentials for use as building materials. Before the utilization, AAMs must satisfy the properties required from the construction sector, such as good durability and long-term service life. These properties mainly depend on the chemical and physical properties of the microstructure of AAMs. In the...

Hydraulic functioning of permeable pile groins: Numerical simulation

Beach erosion, the loss of sand from a beach due to longshore and/or cross-shore sediment transport mechanisms, is a challenging problem. In order to stabilize the beach and to slow down the rate of beach erosion, the construction of hard hydraulic structures is a traditional option. Groins are one of the oldest man-made hydraulic structures...

Geological Controls on Depositional Architecture of Turbiditic Deposits from Stepped Slope-to-Basin Profiles

Deep-water siliciclastic systems are of great societal relevance as their deposits<br/>in subsurface store hundreds of billions of barrels of hydrocarbons in different sedimentary basins worldwide. The sediment density flows that form these systems, termed turbidity currents, are capable of destroying subsea installations, such as...
