Benefit of Vapor Consideration for LPBF Additive Manufacturing Process Simulation
Simulation of laser processes are more and more efficient. In some cases, as welding and additive manufacturing, the physical phenomena are complex, multi-physics and multi-phases, thus some assumptions have to be done. For Laser Powder Bed Fusion, a laser beam melts and vaporizes the ... Read More
Modeling and Multiphysics Simulation of the Directed Energy Deposition Additive Manufacturing
In this paper, we present a study of the simulation of Directed Energy Deposition (DED) Additive Manufacturing (AM) using a multiphysics approach. We use a combination of Heat Transfer in Fluids, Solid Mechanics and Laminar Flow physics to accurately simulate the DED process. The ... Read More
A Framework for Automated, Data-Driven Digital Twin Generation from Multiphysical Simulation Models
A digital twin is a virtual set of information replicating its physical counterpart at the utmost fidelity. Digital and physical twin benefit from bi-directional data exchange that occurs in real time and over the whole process lifecycle. Until now, experts in the design phase have ... Read More
Modeling of Iron Ore Reduction Above the Cohesive Zone of the Blast Furnace
The blast furnace shaft is a huge counter flow reactor in which heat and mass exchange play a significant role in its mathematical modelling. The heat exchange model is already available in COMSOL Multiphysics® via the Local Thermal Non-Equilibrium interface. This multiphysics coupling ... Read More
Simulation of Thin Water Layers on Wafer Surfaces During Bond Chamber Evacuation
Thin liquid layers play a crucial role in many applications. In the case of direct wafer bonding, the amount of water in the bonding interface determines the bonding strength and is therefore of high interest. Simulations can help to study the influence of different technological and ... Read More
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 ... Read More
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 ... Read More
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 ... Read More
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 ... Read More
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 ... Read More
