This paper deals with an integrated numerical and experimental analysis work aiming at the investigation of the thermal distribution inside an industrial furnace built for metal materials treatments. The main goal of the research is to find the geometrical and/or functional parameters responsible for a not homogeneous thermal distribution inside the internal volume of the furnace. During the ...

A hybrid technique based on the use of the FEM and the transfer matrix method is used to identify the frequencies at which thermoacoustic instabilities are expected and the growth rate of the pressure oscillations at the onset of instability. The Helmholtz equation is used to model the combustion chamber and the classical ?-? formulation for the flame model is adopted. The gas turbine combustion ...

A time-dependent COMSOL Multiphysics model of an additive manufacture process, which uses powder consolidation by laser heating was developed, providing a platform to better understanding the manufacture process & provide a tool to reduce resulting distortion & optimization of an additive manufacture process. The model simulates a high intense laser energy source moving along a pre-defined time ...
Tim Poole graduated from Cambridge University with a Masters degree in Engineering in 2008 and immediately joined JDR Cables Systems, a leading supplier of custom subsea oil and gas umbilical systems and renewable energy cables. He started in the Research and Development team, working on creating new products lines and testing umbilicals, which included fatigue, tensile and bend stiffness ...

Industrial applications of fluid mechanics can require to satisfy necessities as diverse as legal norms, optimization requirements and manufacturing constraints. Therefore a Computational Fluid Mechanics software often becomes a must in the development of new devices or the improvement of older ones. Besides the legalistic aspect (such as the European Pressure Equipment Directive), several steps ...

Concentrated photovoltaic systems with high efficiency solar cells are being widely investigated, aiming at improving the cost-efficiency balance in the solar energy field. Different cell types are in use: e.g., high concentration triple junction cells, reaching efficiencies of the order of 35 - 40 % at 1000 suns, and medium concentration mono-crystalline silicon cells, with efficiencies of the ...

In this work we solve a model to simulate the drying of potatoes slices. The model considers both the transport of free and vapor water by applying a mechanistic approach. The critical moisture point (CMP) was considered, since it is a transition zone and it represents the point where water saturation is near from cero and hygroscopic domain begins. The CMP divides the hygroscopic and ...

The Swedish Nuclear Fuel and Waste Management Co (SKB) is responsible for final disposal of spent fuel and radioactive waste. SKB operates SFR, an underground waste repository in crystalline rock. The evolution of groundwater flow within the repository needs to be estimated considering different options for the design of the engineered barriers. The goal is to predict the effects of flow and ...

Bone resorption around hip stems, in particular periprosthetic bone loss, is a common observation post-operatively. A number of factors influence the amount of bone loss over time and the mechanical environment following total hip replacement (THR) is important. Conventional long stem prostheses have been shown to transfer loads distally, resulting in bone loss of the proximal femur. More ...

Several analytical solutions describing the mechanical behavior of a silicon micro membrane deflection, perfectly embedded and subjected to a uniform and constant pressure have been proposed. The obtained results are compared with those obtained by using COMSOL software for a rectangular diaphragm deflection. COMSOL Multiphysics is powerful software for solving problems based on partial ...
