In this work we report a numerical model of a Rotating Disk Electrode (RDE) voltammetry in a finite size domain. Thus, explaining the discrepancy of the diffusion coefficient obtained from the experimental rotating speed, with respect to the literature data. We achieved a very good ... En savoir plus
Fuel vapor restraint systems are used in vehicles to avoid discharge of volatile hydrocarbons from fuel tanks. The topic of this paper is the proper operation of fuel vapor restraint systems depending on the composition of bioethanol-fuel-blends. Experimental data serve as input to a ... En savoir plus
While many biological details in organogenesis have been uncovered, fundamental questions regarding the control of growth and shape during lung and kidney morphogenesis remain unsolved. Using mathematical models, we recently showed that only ligand-receptor based Turing models ... En savoir plus
Standard measuring techniques for thermal conductivity cannot be readily applied to determine the load-dependent thermal conductivity of porous adsorbents, because the local ad- and desorption inside the specimen and the thickness of the specimen are not considered. Hence, in this work a ... En savoir plus
During the last decades, mid-IR (3-12µm) laser sources have attracted attention due to their potential applications in different fields like infrared counter-measures (e.g: missile jamming) and remote chemical sensing. In this context, Onera has been working on the development of non ... En savoir plus
Salinity gradient represents an interesting renewable energy source. Reverse ElectroDialysis (RED) is an ion exchange membrane-based process that convert directly the salinity gradient energy into electric current. Thereby, two solutions at different concentrations are fed into two ... En savoir plus
Carbon dioxide levels are increasing faster than in hundreds of thousands of years due to fossil fuels burning. A serious worldwide interest is growing towards the field of CO2 valorization as a step in transitioning away from fossil fuel economy at the same time of decreasing CO2 ... En savoir plus
Benchmarks are important tools to verify computational models. In the research area of building physics, the so-called HAMSTAD (Heat, Air and Moisture STAnDardization) project is a very well known benchmark for the testing of simulation tools. In this paper we revisit this benchmark by ... En savoir plus
2D-modeling of arc welding in butt-joint configuration was performed in this study considering thermal-structural interactions. Thermal behavior was modeled in COMSOL Multiphysics® using the Heat Transfer Module with weld heat input as a Gaussian pulse whereas structural behavior using ... En savoir plus
Electrospinning is a process where high voltage is applied to produce polymer fibers of nanoscale diameter. Various polymers have been used for this process in molten form or as a solution with an appropriate solvent such as glycerol. The melt solidifies while the solvent evaporates to ... En savoir plus
