Many numerical coupling thermo-hydro-mechanical-chemical models for methane hydrate bearing sediments(MHBS) have been proposed to analyze the mechanical behavior of MHBS during methane gas production. However, most of them are based on finite differential method (FDM) or finite volume method (FVM). Few models for MHBS based on finite element method (FEM) and Galerkin variation principle are ...

The press and blow (P&B) process is widely used to produce glass containers. While the P&B process has demonstrated to be capable of reducing container weight by as much as 33%, it can also induce the formation of micro-checks that weaken container strength. This paper presents a model of the heat transfer due to the intermittent contact of glass with the plunger during several pressing ...

A quasi static indentation test on a laminate composite has been investigated numerically and experimentally. In particular, the test has been implemented by COMSOL Multiphysics® and optimizing the Finite Element and mesh. In addition, the numerical strain results have been validated by the comparison with the respective experimental deformation data that have been obtained by fiber Bragg ...

This paper proposes the design of a 3-Degree of Freedom(DoF) motor based on surface acoustic waves in elastic solids. The rotor is propelled by wave fields, for linear and rotational motion respectively, in the stator, that can be steered by the driving signal of the piezoelectric actuators, which are placed on an elastic plate. The next considerations concern the feasibility of the proposed ...

Engineering design studies of the feasibility of conversion of the High Flux Isotope Reactor (HFIR) from high-enriched uranium to low-enriched uranium fuel are ongoing at ORNL as part of an effort sponsored by the U.S. Global Threat Reduction Initiative program. HFIR is a very high flux, pressurized light-water-cooled and moderated, flux-trap type research reactor whose current missions are to ...

The liquid food product packaging are today predominantly made with board LPB type board (Liquid Packaging Board) composite formed by board, which offers mechanical strength, polyethylene, constituent responsible for protection against the passage humidity, and aluminum foil, which helps protect against oxygen flow. On the day, paper and board are words used as synonyms for each other. ...

For the lack of higher order modes, lumped element (LE) models currently used may be insufficient to predict the system of balanced-armature receiver (BAR). We develop a LE multimode model for BAR in the frequency domain based on the techniques of mode decomposition, truncation, and selection via COMSOL Multiphysics® software. The validation is made by comparing with both the corresponding ...

Nematic Elastomers (NEs) possess both the elastic properties of rubbers and the orientational properties of liquid crystals. Those two properties makes the configuration of NEs very sensitive to isotropic-nematic phase transition. Our goal is to replicate with numerical experiments the phenomena of shape formation in Twist-Nematic Elastomers (TNEs): a flat bar evolves into a helicoidal shape ...

With the ever changing energy requirements & demand for better communication links across the planet, subsea umbilical & cable requirements are becoming more stringent. Where longer service life at a lower cost is now expected from manufacturers. In addition to this, with the need to exploit more sustainable energy sources from offshore wind & wave, where extreme weather conditions are ...

The design of ESS-Bilbao RFQ (RadioFrequency Quadrupole) linear accelerator cavity using COMSOL Multiphysics is presented. The work includes geometry definition, electrostatics, electromagnetic and thermomechanical coupled simulations. The main part of the work corresponds to the electromagnetic design. Geometry construction and meshing is very challenging, involving large models (3 m long) with ...
