Puffing of biomaterials involves mass, momentum and energy transport along with large volumetric expansion of the material. Development of physics-based models that can describe heat and moisture transport, rapid evaporation and large deformations can help understand the puffing process. In this context, a fundamentals based study of salt-assisted puffing of rice is described. A multiphase model ...

Performance of tactile sensation is affected by fingertip deformation characteristics produced when touching objects. Tactile performance of human fingertips is strictly associated with activity of the nerve endings and sensitivity of the soft tissue within the fingertip to the static and dynamic skin indentation. In this study, a Finite Element model, based on the physiological structure of the ...

As embalagens de produtos alimentícios são hoje em dia predominantemente feitas com cartão tipo LPB (Liquid Packaging Board) e usualmente estocadas de forma empilhada, tanto nas prateleiras como nos depósitos dos supermercados. O LPB é um compósito multicamadas de construção complexa, envolvendo, tipicamente, papel produzido com fibras virgens, polietileno e alumínio. O alimento líquido ao ser ...

A medical ventilator is an imperative device used to save life by delivering an assortment of air and oxygen into and out of the patients’ lungs to administer breathing or to assist obligatory breathing. The commercially available diaphragm based pressure sensors made up of silicon measure the air and oxygen flow. The proposed work utilizes the Piezo electric material for the pressure range ...

Resistive heating filaments used in high temperature applications at 2000°C and above are often made of refractory metals. The lifetime of such filaments is mainly limited by creep deformations which can in the worst case lead to a short circuit between filaments and other furnace components. With the aid of COMSOL Multiphysics software, the time-dependent creep deformation behavior of a heater ...

Describing and predicting the extent of the physicochemical processes as well as geometrical deformation taking place during food transformation is of major importance to control food functional properties. Unfortunately, only a few food-matrix models consider deformation particularly because of large deformation. In the case of a starchy product such as rice, water transport and swelling ...

This paper is concerned with the fatigue behavior of complex, three-dimensional, stress concentrations under multiaxial loadings. Starting from the stress field obtained from a linear elastic analysis and taking advantage of the so-called implicit gradient approximation, an effective stress index connected with the material strength is calculated. Besides, this work summarizes a first ...

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 ...

This paper will present a numerical model based on COMSOL Multiphysics suited to simulate the dynamic response of a catenary mooring (or a submarine cable). In general, mooring lines are subject to a direct wave load (e.g. drag, inertia) in addition to the movement of the vessel to which they are linked. Tests were carried out at the wave flume of the Maritime Laboratory of IMAGE Department, ...
