Marangoni flow affects the heat and mass transfer occurring in the molten metal regions in welding and additive manufacturing processes. It originates from the surface tension gradient (∂γ/∂T) induced at the melt pool surface due to the temperature difference. The flow pattern within ... Per saperne di più
A numerical finite element model of one human brain is built in COMSOL in order to study a particular form of hydrocephalus, the so called Normal Pressure Hydrocephalus (NPH). The geometry of the ventricles and the skull is obtained by Magnetic Resonance Imaging (MRI) and imported in ... Per saperne di più
This talk is for intermediate-level users of COMSOL who, like the present author, are relative newcomers to numerical simulation but have a strong grounding in Hydrodynamics or related areas of Mathematical Physics. Most turn-key Computational Fluid Dynamics packages, including COMSOL ... Per saperne di più
In a water based electrolytic polishing process, the formation of molecular hydrogen at the cathode is unavoidable and it can contribute to the formation of surface defects at the anode side. This paper presents the work to model and simulate the molecular hydrogen flow inside radio ... Per saperne di più
During examination of molecular gas flow in freeze dryers in near-vacuum properties, an idea came up to model a molecular fish trap nozzle. An appropriate shape of this fish trap nozzle allows to separate free flowing molecules into 2 chambers, and obtain a pressure gain in a isothermal ... Per saperne di più
In this study the inverse Jet-ECM process of micro bores is investigated by help of multiphysics simulations. Based on the micro bore of a commercial sample nozzle a model geometry was derived. For simulating inverse Jet-ECM a transient model has been developed. Electric currents and ... Per saperne di più
In this work, a MEMS based condenser microphone [1,2] using Polyimide as the diaphragm has been designed. The microphone structure has a backplate placed on top of the diaphragm. The backplate and the diaphragm are made up of polyimide. The two polyimide plates are separated by air gap ... Per saperne di più
This paper presents the design and simulation of micromixer for Lab-On-Chip (LOC) applications. There are two types of micromixers: one is an active micromixer and another one is a passive micromixer. This paper investigates microfluidic flow characterization and mixing rate of two ...

For the SAFARI Imaging Spectrometer, part of the SPICA satellite payload, a Calibration Source is under development. Challenges in the design include the low cooling power (few mW) available at cryogenic temperatures. COMSOL Multiphysics® simulations were used extensively in the design ... Per saperne di più
Analytical methods used for inductance calculation of toroidal coils yield large errors in the case of coils sparsely wound on low permeability cores. Numerical field calculations can provide “exact” figures. We have outlined several simulation methods. Simplifications, assumptions, and ... Per saperne di più
