Spectral analysis of thermal emission from melt pool during laser material processing
Laser technologies such as welding, cutting and metal deposition are widely used in the industry. High quality requirements regarding process products cause that there is often a need to monitor the process. For this purpose, optical sensors integrated with a laser head are often used. ...

Simulation and comparison of a band gap metamaterial using a relaxed micromorphic model
We present here an architectured band-gap metamaterial, filtering mechanical waves in specific ranges of frequencies which, by its very specific geometry, challenges the simulation of linear elasticity problems including such elements. This unorthodox behaviour can be described as a ... Read More
A first approximation to the modeling of vapor plume evolution in laser welding
A quantification of spatial and temporal evolution of laser-induced plume would enhance the comprehension of high speed imaging results and allow optimizing the acquisition conditions for the emission spectroscopy. What temperature and concentrations of the evaporating species are ... Read More
Membrane Electrode Assembly for CO2 Electroreduction: Influence of Flow Channel Design
Electrochemical reduction of CO2 to value added chemicals is a promising strategy to mitigate its emission from atmosphere and close the carbon cycle. Although the knowledge on designing electrocatalysts for CO2 electroreduction exists, challenges are associated with developing CO2 ... Read More
Numerical simulation of non-aqueous phase liquids imbibition in unconsolidated porous media
A three-dimensional multiphase laboratory experiment was simulated with a view to evaluating the subsurface distribution of non-aqueous phase liquids (NAPL). The experiment was set-up to reconstruct the migration of hydrocarbon-leaks, occurring in the earth´s surface, predominantly ... Read More
Flow and heat transfer simulations as a development tool for a novel microcalorimeter
Calorimetry is the method of choice for determining one of the most elementary physical quantities: heat, Q [in J]. Depending on the individual issue a wide range of techniques, devices and methods are available for users [1]. One approach is called isothermal microcalorimetry (IMC). It ... Read More
Numerical simulation to improve the H2O-barrier property of films by integration of water absorbers
Flexible electronic devices are very sensitive against the ingress of oxygen and water vapor from the atmosphere and therefore must be protected by encapsulation with high barrier films. Typically these films contain at least two or three inorganic barrier layers separated by polymeric ... Read More
Finite element modelling of three-phase non-isothermal flow in heavy oil reservoirs- case study SAGD
Thermal enhanced oil recovery methods form the majority of the enhanced oil recovery projects worldwide. Among the thermal methods, steam injection is the most effective and most applied process in petroleum industry. The main mechanism of the steam injection method is the reduction of ... Read More
3D unsteady Benard-Marangoni instabilities during the evaporation of the volatile sessile drops
Our current research is focused on thermal Marangoni instabilities in sessile ethanol drops which develop spontaneously during evaporation. Our current problem for numerical model is 3D unsteady with moving interface of a sessile drop under forced evaporation and showing internal flow ... Read More
The use of 3D printed material for trunk exoskeleton system
Since the 60’s, exoskeleton technology has fascinated scientists and engineers alike, from examples such as the early GE “Handyman” through to model XOS, a military grade heavy duty system. This technology can also be found in the clinical setting, where systems can offer patients, who ... Read More
