CO2 storage in basalts: the impact of mineralisation on the hydromechanical response of the material

Carbon mineralisation in basalts is a promising cost-effective way to permanently store CO2 in view of climate change mitigation. In this work, the impact of carbon mineralisation on the hydromechanical properties of a basaltic sample is studied. Unlike pr ...

Assessment of the Thermal-Hydraulic Performance of the European DEMO NbTi Bus Bars

Rainer Wesche, Kamil Sedlák, Roberto Guarino

We present a numerical assessment of the thermal-hydraulic performance of the NbTi bus bars designed for the European DEMO. We consider the CS, TF and PF bus bars, as well as two alternative TF options for high-current operations. The main sources of stati ...

3-D granular modeling and in situ X-ray tomographic imaging: A comparative study of hot tearing formation and semi-solid deformation in Al-Cu alloys

Michel Rappaz, Jean-Marie Drezet, Meisam Sistaninia

The mechanical behavior of partially solidified Al-Cu alloys is investigated to assess the influence of mushy zone deformation on hot tearing. For this purpose, the results of a semi-solid tensile test conducted in situ using X-ray microtomography are comp ...

Dynamic saturation curve measurement for resin flow in glass fibre reinforcement

Véronique Michaud

A methodology is presented to determine the saturation curve of a resin/glass fabric system, during infiltration in a transparent mould under constant flow rate. Video acquisitions are transformed by image analysis into saturation level versus position and ...

Numerical modeling of laminar annular film condensation for different channel shapes

John Richard Thome

This paper presents a theoretical and numerical model to predict film condensation heat transfer in mini and micro-channels of different internal shapes. The model is based on a finite volume formulation of the Navier-Stokes and energy equations and it inc ...
