This paper deals with the nonlinear magnetic analysis of a 100 Nm, multi-disc, magnetorheological fluid rotary brake or clutch, carried out with COMSOL Multiphysics. Along with the results of the analysis, the paper presents merits and limitations found in the use of the software and introduces current efforts to include in future simulations the thermal and the mechanical responses of the ...

Politecnico di Milano
An efficient simulation of the inverse extrusion process has been performed through the coupling of three modules in COMSOL Multiphysics: fluid-dynamics, general heat transfer and ALE. The strain, the strain rate, and the stress field can be completely defined after the complete definition of the velocity field of the material under the action of the tool. The definition of the stresses and of ...

Buffer chemical polishing is a cheap, simple and effective processing technique for single grain high gradient and polycrystalline lower gradient cavities. This paper describes the thermal-fluid finite element model adopted to simulate the process, the experimental flow visualization tests performed to verify the simulation and a novel device fabricated to solve the problem.

The objective of this paper is to present the results of a numerical study undertaken to investigate the hydrodynamics and turbulent transport and mixing inside two contact tanks, which have the same channels but different location of the baffles. Transient concentration data were used to derive the residence time distribution (RTD) function for both tanks in order to evaluate and compare ...
Finite Element Analysis of Electro-mechanical Deflection of Cantilevers for SPM and MEMS Applications

University of Bologna
The understanding of the distribution of electrostatic forces at the nanoscale is of fundamental importance for the development of nanotechnology. In this work, in order to quantify the EFM cantilever/tip-sample interaction, we present a 3D static Finite Element Analysis of the electromechanical interaction between conductive probes and samples, using COMSOL Multiphysics. The simulation ...

This research presents a model describing the behavior of fluids during a septic filling processes. Numerical simulations were performed to investigate the laminar flow and rheological behavior of shear thinning and Newtonian fluids in 3-dimensional steady state and time-dependent configurations. The mass and momentum balance equations were solved with the finite element method using ...

This paper presents a two dimensional model of a Preferential Oxidation Reactor. The main aim of the mathematical model was to investigate the process performance of the reactor by parametric analysis. Temperature and concentration profiles along the length of the reactor were evaluated in order to enhance optimization and control of the PROX unit.

This paper describes an example of full fluid structure interaction. The 2D dynamics of a box-type pile-anchored floating breakwater is solved by means of two models using COMSOL Multiphysics . Simulated wave transmission and vertical displacements of the floating breakwater agree well with physical model results.
