In this paper, we create models with the use of COMSOL Multiphysics to predict evolution of temperatures and crust formation in meat during barbecuing and oven roasting. Sensitivity to parameters is analysed and predictions are compared to experimental data from literature.

Shape Memory Alloys are good candidates for being used as passive dampers, strain sensors, stiffness or shape drivers. In order to develop the use of these alloys in structural vibration control, we present in this paper how to implement a phenomenological model based on the Rl model in COMSOL Multiphysics. We use this implementation to simulate internal loops in order to characterize the ...

In this work, we present the modeling of V-shaped silicon micro-cantilevers. The sensitivity of different V-shaped silicon cantilevers is estimated, as a function of the geometrical dimensions of the cantilever.

Flows in highly heterogeneous media are found in many practical fields, such as hydrology, petroleum engineering, and chemical engineering. The case of two-region heterogeneous media (fractured media, catalytic beds, etc.) plays a fundamental role. The different questions associated to this specific case are illustrated in this paper for two different kinds of transport: (i) flow of a slightly ...

Elastic and poro-elastic models of ventricular dilatation in hydrocephalus are presented in this paper. An important result was the accumulation of fluid capping the horns of the ventricles. This indicates the importance of interstitial fluid in calculating of the deformation of the brain.

The aim of this work is to study tissue morphogenesis as a consequence of the constitutive cells dynamics. Tissue morphogenesis is modelled as a cellular system coupled with a global chemical control. p> Two concrete examples are presented, the secondary growth of conifer trees and the epithelial invagination.

The hyporheic zone is defined as an area where water and matter exchange through the sand, gravel, sediments and other permeable soils under and beside streams. Its impact on the hydro-system function is determined by the proportion of subsurface biogeochemical reactions and the fluxes of water exchanging with the hyporheic zone and flowing through the porous sediments. The objective of our ...

In this paper, we investigate the compressional wave generation in droplets and use different techniques to correlate the compressional wave generation to the shape of the droplets. Results show a good correlation between eigenmodes predicted by the theory and those experimentally observed.

In this paper, we study a novel type of NEMS - tunnel junctions mounted on thin membranes. Mechanical stress applied to the junction induces changes in the height and length of the barrier, allowing the modulation of the tunnelling current.
