Investigation of the Efficiency of a Supersonic Rocket Aerosol Collector
The aim of this investigation is to apply computational fluid dynamics simulations to support the design development of an impaction-based probe collector. This collector should allow submicron aerosol impactions in the supersonic free stream radially aside a sounding rocket body in the ... En savoir plus
Numerical Calculations of Gas Flows in COMSOL Multiphysics® for Nuclear Physics Studies
Studying the properties of nuclei produced in various types of nuclear reactions at accelerator facilities is challenged by small production yields and short half-lives of isotopes of interest, therefore making high efficiency and fast timing essential parameters of the experimental ...

Towards Data Driven Design of Flow Blurring Atomizer
Liquid atomization relies on a variety of forces that disturb the surface of the liquid. In the case of flow-blurring (FB) atomization, turbulent structures are induced within the liquid channel to achieve this effect. It is known that the transition from the conventional flow-focusing ... En savoir plus
Bubble Detachment from the Surface of a (Photo)Electrode
Many (photo)electrolytic devices involve the generation of bubbles (e.g., hydrogen, oxygen). In these devices, bubble coverage on the surface of the electrode not only decreases the active area, but also induces optical loss.[1,2] Efforts in understanding the bubble detachment process ...

Elastohydrodynamics of Roll-to-Plate Nanoimprinting on Non-Flat Substrates
Roll-to-plate nanoimprinting is a manufacturing method to replicate micro- and nanotextures on large-area substrates with UV-curable resins. Figure 1 shows a schematic of the roll-to-plate imprint process, which is considered in this study [1]. It uses several rollers, for imprinting and ... En savoir plus
Simulation Based Design of a Bladeless Centrifugal Flow Compressor
The bladeless centripetal flow turbomachinery or disc turbine was invented by Nikola Tesla with the aim to realize a turbine with higher efficiency and simplicity compared to the state of the art at that time. Unlike conventional turbines, the disc turbine does not use rotor blades. ... En savoir plus
Reinforcement Bars Corrosion in a Carbonated Concrete
In the construction sector, the concrete and the steel bars represent still the key components, although they are very vulnerable by the atmospheric agents, as in the case of their degradation caused by corrosion. The value of the concrete carbonation may enhance the corrosion around the ... En savoir plus
HETT22 – A COMSOL® App to Accurately Simulate, Plan and Monitor Concrete Castings
HETT22 is a software developed through joint efforts by Deflexional and Heidelberg Materials. It enables construction companies to accurately simulate, plan and monitor heat and strength development in concrete after castings. Leveraging the power of the COMSOL Multiphysics® software, ...

A Multiscale Approach to Simulate Vacuum Drying of a Packed Bed of Spray-Frozen Particles
Preservation of biopharmaceuticals by spray freeze-drying is of great interest as it involves gentle drying and can be easily integrated with continuous manufacturing strategies. The drying of packed beds have been extensively studied experimentally, but a detailed mathematical model of ... En savoir plus
Monte Carlo Simulation to Model Natural Variability in Food Drying
Convective drying of fruits and vegetables is a widely used preservation method and serves to reduce food waste, to make them available off-season and to reduce weight-related transport costs. However, the high energy consumption and impact of the process set-up and process settings on ... En savoir plus
