Modeling Confinement in Quantum Dot Solar Cells
The efficiency of the first and second generations of solar cell has hardly seen dramatically increase over the years, in which most PV cells cannot use about 55% of the energy of sunlight because a single material can not capture the entire spectrum of sunlight. To achieve the objective ... Read More
Finite Element Simulation of Impulse Arc Discharge
Damages caused by lightning overvoltages remains to be an important issue for electrical industry, putting limitations for efficiency of transmission and distribution of electrical energy. Modern solutions for lightning protection such as multichamber arresters (MCA) for overhead ... Read More
Free Surface Deformation of the Weld Pool in Orbital Narrow Gap GTA Welding
Arc current welding is a widespread process in heavy industry for the assembly of metallic components. In order to ensure the good quality of assemblies welds, it is appropriate to master the welding process but also to have a deep understanding of interactions with the weld pool and ... Read More
Transient Simulation of the Removal Process in Plasma Electrolytic Polishing of Stainless Steel
Plasma electrolytic polishing (PeP) is an electrochemical method for surface treatment. In detail PeP is a special case of anodic dissolution [1] that unlike electrochemical polishing requires higher voltage and uses environment friendly aqueous solutions of salts. When the process ... Read More
Finite Element Prediction of Laser-Material Interaction Using COMSOL Multiphysics®
Surface engineering is a key technology used in a wide range of sectors in industry. Among other techniques, it involves adding functionality to a surface. This can be performed by creating a specific topography to a surface using laser texturing. The objective of the work presented in ... Read More
Adaptive Mesh Refinement: Quantitative Computation of a Rising Bubble Using COMSOL Multiphysics®
The mesh is a key component in numerical simulations as it represents the spatial discretization of the model geometry. To accurately measure the variation of the unknowns, a relevant mesh should have a high density of degrees of freedom in regions where the norm of the gradient of the ... Read More
Advanced Loudspeaker Calculator – an Example of COMSOL® Apps Utilization
Developing a new loudspeaker design requires not only knowledge and experience in the field, but also an access to verified and efficient tools. HARMAN’s Virtual Product Development (VPD) team has developed a Comsol Application to serve at the early stages of the design process. The app, ... Read More
Acoustic Modeling of a “Minute Repeater”
The project was ordered by a Swiss watchmaker. The aim was to modelize and optimize the acoustic of a minute repeater on one of the high range item made by the watchmaker. Therefore we based our work on a simplified geometry made by Creo. The mesh model includes the gongs, the bottom ... Read More
Light-tissue Interaction Modeling Using COMSOL Multiphysics® for Multi-layered Soft Tissues
Soft tissues are longest tissue structures found throughout a human body. It plays a vital role in connecting, providing support or surround other structures and organs of the body. Muscles, skin, tendons, ligaments, nerves, fibrous tissues, fat, blood vessels are commonly classified as ... Read More
Two-Phase Flow Modeling of Metal Vaporisation under Static Laser Shot Using a Double ALE Method
Additive manufacturing gathers technologies where near net shape components are produced by depositing successive layers of materials. Among these technologies, the Layer Beam Melting (LBM) process – often referred to as Selective Laser Melting (SLM) – is garnering industrial interest, ... Read More
