Technical Papers and Presentations

Airbus Safran Launchers is the market leader in Space Launch services. Rocket engines are among the most powerful machines that exist. The core of the rocket engine is the combustion chamber where in the case of liquid propellant rocket engines, fuel and oxidizer are injected, mixed and ... Read More

The main mechanisms of acoustic attenuation in a bundle of fibres typical of lightweight fibrous porous materials are the dynamic viscous drag forces on the surface of the fibres, and the thermal heat transfer between the solid fibres and the surrounding fluid. Microstructure models ... Read More

In order to improve hydrogen production in an ethanol reformer it is needed to understand what happens inside it. Also, a simulated model can simulate different work conditions avoiding the necessity of doing tons of experiments. A 3D computational fluid dynamics simulation study of ... Read More

Since the industrial demand in the energetic, mining and oil & gas sectors has increased exponentially these last decades, security standards and fire protection methods are extremely important not only for the employees, but also for the infrastructure involved in production areas ... Read More

The machining of hardened steel or powder metallurgical steel, for example to manufacture impact extrusion punches, is a big challenge for conventional machining technology as milling or turning. A non-conventional machining technology is Electrochemical Machining (ECM), which allows ... Read More

This work is a first evaluation of the validity of the frozen rotor approximation for the simulation of a stirred beaker. The agreement is good, further analysis will be carried before using the model to optimize labscale setup dedicated to IL electrochemistry. Read More

The vestibular systems are very important to balance of body. But some people have vertigo and dizziness caused by vestibular disorder. It is well known how the symptom appears physiologically. The benign paroxysmal positional vertigo (BPPV) which comes from moving an otolith in ... Read More

The JPM Silicon GmbH presents a novel method for the production of solar grade silicon in the microwave oven. This method can specially reduce the energy costs and increase the efficiency of the process. A numerical model is developed which depicts the physical, chemical and ... Read More

Time-dependent multiphysical simulation of pulsed and continuous laser welding of dissimilar metals, based on Moving Mesh (ALE) approach, is proposed. Strong coupling between heat transfer, laminar compressible flow and ALE is used. The model was validated for a case of single ... Read More

Additive Layer Manufacturing (ALM) methods, like Electron Beam Sintering (EBS), constitute an interesting process concerning the production of small series and customized products. However, transient effects occur during processing due to the different physical principles of an electron ... Read More
