We show a new, favourable space-saving method to host a neutron polarizer in the iron-containing monochromator shielding of a time-of-flight spectrometer for cold neutrons. In this poster you can learn e.g., how to create a robust, homogeneous, rectangular magnetic field (here realized by permanent magnet queues inside an iron tube). The time-of-flight spectrometer FOCUS at the spallation ...

We have used COMSOL Multiphysics® software to design a micropipette for single -cell gene expression profiling. The micropipette design allows us to insert it into a single-cell to extract genes through dielectrophoresis. As dielectriphoretic force depends on the applied electric field (E) and its gradient (∇E^2), we have successfully used COMSOL to calculate E and ∇E^2 in the vicinity of the ...

In this paper an electromagnetic solenoid actuator (EMVA) consisting of an upper and lower electromagnet, a linear moving armature and two preloaded springs is considered as a potential approach in Variable Valve Actuation (VVA) Systems for Internal Combustion Engines. In opposition to common approaches the underlying EMVA make use of a permanent magnet in the upper electromagnet. The analysis ...

In principal, the calculation of the magnetic state inside a magnetic object requires the evaluation of the field in the entire unbounded space. With finite element methods restricted to finite domains, commonly auxiliary domains are employed which result in a non-physical cut-off. Not only are these additional domains result in an increased number of degrees of freedom which are strictly ...

Although resuscitation during pregnancy is relatively uncommon and rarely causes death, they have a particularly large impact in terms of the mortality of the unborn child and long-term effects on families and society as whole. In this paper, we present a new 3D finite element model of a pregnant female torso which accounts for presence of amniotic liquid and calculate current density ...

This work presents the results of a 3D numerical magneto-hydrodynamic (MHD) simulation of an electromagnetic DC pump for liquid metal using a rectangular metal flow channel subjected to an externally imposed transversal inhomogeneous magnetic field. In this study. 3D numerical simulation based on the finite element method was carried out using the computer package COMSOL Multiphysics 3.5a. The ...

In the present work, we have studied the electron transport properties of single silicon nanowire using Semiconductor Module of COMSOLMultiphysics software. We construct a MSM (metal-semiconductor-metal) model where metal is selected as copper and semiconductor is taken as silicon. Silicon is doped with n-type impurity by increasing doping concentration. Further, the Schottky diodes formed at ...

The understanding of pH-sensitive hydrogel swelling response in different buffer environmental condition is essential for its use in different practical applications. This necessitates its simulation in steady state and transient conditions. This paper mainly deals with the details of the numerical simulation performed by developing coupled formulation of chemo-electro-mechanical behavior of ...
