Two friction stir welding models are presented – a global thermal model using the temperature dependent heat source and a local material flow and heat generation model allowing for detailed investigation of different contact conditions. The two models are coupled into a larger local-global model. The flow model includes frictional dissipation from the contact between the work piece and the ...

Methanol synthesis is a typical reaction in heterogeneous catalysis. In this work, we have studied a laboratory fixed-bed reactor packed with a Cu/Zn/Al2O3 catalyst in both adiabatic and isothermal tubular operational modes. A methanol synthesis kinetic model was implemented in COMSOL Reaction Engineering Lab. Both 1D and 2D pseudo-homogeneous dispersion models were applied to describe the mass ...

Efforts involving simulation of transmission line networks necessitate the accurate values of the parameters of the lines. In this paper, as an attempt in estimating such parameters, the parameters of high voltage asymmetric power lines are calculated. In the process of estimation, the three phase equivalent circuit model is used. The resistance and inductance of such lines are dependent ...

This paper presents the mathematical modeling for the analysis of the magnetostrictive materials, which describes the behaviour of the magneto-mechanical coupling in a rod of magnetostrictive material and capturing it in COMSOL® to produce a predictive and detailed analysis. A simulation of the behaviour under harmonic excitation is done in this work.

Vortex-induced vibration is a major cause of fatigue failure in submarine oil and gas pipelines and steel catenary risers. Even moderate currents can induce vortex shedding. In this paper, COMSOL Multiphysics is applied to study the flow pattern around submarine pipeline spans, and predict the amplitude and frequency of the vortex induced vibrations. The sensitivity of the computational fluid ...

Raman spectroscopy is a commonly used tool in biodiagnostics and sensor technology. Surface-enhanced Raman scattering provides high signal enhancements especially at nanostructured metallic surfaces. In this paper the electromagnetic Raman enhancement from different metallic nanostructures - including gold coated gratings, spherical and hemispherical particles - is calculated by using the finite ...

Surface acoustic wave (SAW) devices based on Rayleigh wave, shear wave, love wave, acoustic plate mode (APM) wave and flexural plate wave have been explored for sensors, actuators and telecommunication applications. An interdigital transducer (IDT) is a metallic comb-like structure fabricated over piezoelectric substrate. SAWs are generated over the substrate by applying electrical signal to the ...

Preparative chromatography is an important separation method where the simulated moving bed (SMB) technology is an increasingly used separation process for binary mixtures. Several chromatographic columns are arranged in a ring where the feedings and drains are changed cyclically to maintain a continuous separation. For this reason, an adaptive controller is proposed to adjust the flow rates ...
