Acoustic wave propagation due to the breakage or slippage of reinforced wire in water-filled prestressed concrete cylinder pipe (PCCP) attracts interest in non-destructive pipe testing. Current practice of acoustic emission (AE) detection and wire-break related events (WRE) recognition ... En savoir plus

The mesh is a key component in numerical simulations as it represents the spatial discretization of the model geometry. To accurately measure the variation of the unknowns, a relevant mesh should have a high density of degrees of freedom in regions where the norm of the gradient of the ... En savoir plus

This paper is about the influence of the diffusion coefficient when simulating mixed electrode materials. The results show that when simulating dynamic behavior of a lithium ion battery cell with mixed electrode material the diffusion coefficients is very important. En savoir plus

This poster presents a numerical modeling approach for hygrothermal behavior of bio-based materials. The mathematical model describes the heat and moisture transfer through a wall of bio-based materials. The studied wall is subjected to both convective heat transfer and moisture flux ...

Reducing HVAC energy consumption in buildings has provoked a lot of thought and has, subsequently, drawn a lot of attention. Out of the several methods that have been introduced to achieve this goal, the usage of Phase Change Materials (PCMs) in the structural components is one of the ... En savoir plus

Assessing the severity of the internal corrosion of structures is of paramount importance in the oil & gas industry. Modelling and simulation of this process proved to be key techniques to understand its mechanism and the main factors influencing its severity [1-4]. Considerable ... En savoir plus

In the framework of the Austrian FFG project SaLüΗ!, a compact mechanical ventilation system with integrated micro-heat pump was developed. The aim was a high level of prefabrication and a compact design allowing for installation also in small flats, e.g. into the façade. Due to the ... En savoir plus

In this paper, a carbon dioxide sensor is introduced. At present many CO2 sensors are available, but they all required power in the order of few watts, therefore they are not suitable for long term unattended operation. This paper gives the brief description of CO2 sensor modeling using ... En savoir plus

Many materials require functionally graded cellular microstructures whose porosity is engineered to meet specific requirements of diverse applications. It has been shown in previous work that the bubble growth rate of a polymeric foam can be influenced by the surrounding acoustic ... En savoir plus

The residual stresses developed in a stiffened panel manufactured using Electron Beam Freeform Fabrication (EBF3) process were studied. EBF3 process is a layer additive process that can be used to build near-net shaped parts directly using computer controlled techniques, which can be ... En savoir plus
