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 ... Read More

Additive Manufacturing is revolutionizing the industrial sector for complex and individualized metallic components. The most limiting factor of the widely established laser beam melting technology is the scan velocity due to inertia of the mirrors [1]. In electron beam melting (EBM), ... Read More

Solar energy storage has been an extensive research topic among the several thermal energy applications over the past three decades. Thermal energy storage (TES) systems in general, improve the energy efficiency of systems and sustainability of buildings by reducing the mismatch between ... Read More

Introduction: The simulation of coupled heat and moisture transfer in constructions is becoming even more important in the last years. COMSOL Multiphysics represents a powerful tool for this kind of simulations as shown in [1,2,3], although applications in this area are still rare. For ... Read More

Low cost high energy density batteries that can be charged and discharged rapidly are required in a number of applications. Tapping energy from renewal resources such as solar, wind and tide requires rapidly generated energy to be first stored and then used round the clock. Storing ... Read More

This work investigates the possibility of thermal activation of future tunnels to heat and/or cool the surface buildings or infrastructure such as subways stations. The principle is to insert pipes in the tunnel lining segments, which are connected to a geothermal pump. A heat transfer ... Read More

The paper illustrates the use of COMSOL (via the “Coefficient-Form PDE” option) for obtaining the relativistic quantum mechanics wave function Ψm(x,y,z,t), m=1,4 as a solution to the time dependent Dirac equations. Once having Ψm(x,y,z,t), it can be used to compute the probability ... Read More

In The Netherlands rising dampness problems due to flooding of rivers and high groundwater levels form an essential treat for monumental buildings and heritage. A number of cases exists where rising dampness problems lead to the deterioration of wall finishes but also of valuable wall ... Read More

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 ... Read More

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 ... Read More
