Multiscale modelling of chloride transport in cementitious materials at the atomic and pore network scales

To reduce the CO2 footprint of construction materials, concrete producers blend their cement with Supplementary Cementitious Materials (SCMs). And even though such blended systems are eco-friendlier than the Ordinary Portland Cement (OPC), they are required to respect standards. In this context, understanding and predicting the durability of...

Microgeneration technologies in new build housing: Technological trajectories and user experiences

The UK has set a target for a reduction in CO2 emissions by 80% by 2050 compared to 1990 levels. The domestic sector accounts for 25% of UK emissions from the generation of heat and electricity for homes. For this sector to move to a low-carbon path, it will need to transform the environmental performance of housing. The transformation will...

Influence of the nozzle outlet face on near flow field mixing

The shape of the nozzle geometry is increasingly attractive in heating, ventilation and air conditioning applications. However an important consideration in the design of nozzle geometry is its effect on the dynamics of near flow field jet and to minimise the manufacturing cost for practical applications. In this investigation the effect of an...

Improving multigrid for 3-D electro-magnetic diffusion on stretched grids

We evaluated multigrid techniques for 3D diffusive electromagnetism. The Maxwell equations and Ohm's law were discretised on stretched grids, with stretching in all coordinate directions. We compared standard multigrid to alternative multigrid approaches with linewise smoothing and semi-coarsening, both as a stand-alone solver and as a...
