The novel concept of distributing the food super chilled (partially frozen) in order to prolong the shelf life has been suggested in the project. The temperature of the distribution chain is envisaged to be +5C. The suggested application has the following advantages: 1) Partial thawing of the product in the distribution chain makes it easier to handle. 2) The unhealthy and labour-demanding ...

In this paper a finite element method(FEM) study of a surface acoustic wave (SAW)device excited by electrostatic coupling method is performed by using COMSOL Multiphysics. We have modeled a Rayleigh wave type SAW device by choosing YZ Lithium niobate as the substrate. The effect of external radio frequency (RF) field to the SAW device is analyzed. The effect of distance between the contactless ...

Opalinus clay is currently being proposed as a potential host rock for radioactive waste repository in deep geological formation. It is then important for performance assessments to understand the transport properties of such rocks. Clay materials are characterized by low hydraulic conductivities and diffusion is assumed to be the main transport mechanism. The studied rock is a complex assembly ...

The present work is aimed at evaluating the capabilities of COMSOL Multiphysics® to treat heat transfer in Molten Salt Reactors (MSR). The analyzed situation is represented by the molten salt in turbulent regime flowing through a cylindrical channel surrounded by graphite, with both the fluid and the solid generating power. A suitable validation framework has been set up on the basis of an ...

In an experimental nuclear fusion facility dust is generated both during normal machine operations and by macroscopic erosion of the plasma facing materials due to intense thermal loads. This dust can be mobilized by air ingress in case of LOVA (Loss of Vacuum Accident) threaten safety of workers and public. A small facility, Small Tank for Aerosol Removal and Dust (STARDUST), was set up in ...

A solidification process of casting explosives in shell is studied in this paper. An enthalpy method approach is used to model the solidification process. Both the thermal and mechanical effects are taken into account. An ALE (Arbitrary Lagrangian-Eulerian) method is used to represent the physical deformation due to solidification. Results from the model are verified against experimental ...
