The heat and mass transfer processes occurring in a domestic oven is in detailed analyzed in this work, with the final objective of improving the global energy efficiency of the system. A 3D Finite Element model developed with a Multi-physics approach is validated with the experimental data from the standard test for energy consumption of the European Union (EN 50304:2001). In this test a brick ...

Sound energy distribution patterns within enclosed spaces are the basic concerns of architectural acoustics. Energy decays are analyzed for major acoustical parameter estimations, while spatial energy distribution and flow vectors are indicative in the analysis of sound energy circulation and concentration zones. In this study the acoustical field of a real-size multi-domed monumental ...

We simulate a Capacitive Micromachined Ultrasound Transducer (CMUT) using COMSOL Multiphysics® software. The CMUT is an electromechanical system, therefore, we couple the physics of electrical and structural mechanics to describe its dynamics. We obtain the distributions of the electric field and the stress as a function of time. Finally, we derived the time evolution of the device for several ...

An important part of the society considers an increased share of renewable energies as an integral part of a strategy towards a sustainable future. As far as heat supply is concerned, this can be achieved using solar thermal collectors, borehole heat exchangers or trough the combustion of biomass. This article shows two applications of two configurations of twisted conduit inside the external ...

Digestion is the process of breaking down food into smaller components, by mechanical and enzymatic action in the digestive tract, so that the smaller nutrient molecules can be more easily absorbed in the intestinal tract. To study and analyze the human digestive process, different methodologies have been used in the past. In general, in vivo feeding studies with humans provide the most accurate ...

Museum buildings strive for a stable indoor climate to reduce the risk of cultural object degradation. An incorrect temperature or relative humidity can induce or accelerate deterioration processes such as biological, chemical or mechanical degradation. In order to reduce these risks, museums often install (parts of) an HVAC system to control the indoor climate of exhibition rooms. The indoor ...

Introduction Thermal management is a key challenge in development of modern microelectronics systems. This is becoming an increasingly critical area of microelectronics packaging design due to the ever increasing levels of miniaturisation, integration and operating frequency which result in significantly higher power densities. This study looks to address this challenge through advanced ...

Mutually-soluble solvents can enhance oil recovery both in completely and partially water wet fractured reservoirs. When a strongly or partially water-wet matrix is surrounded by an immiscible wetting phase in the fracture, spontaneous imbibition is the most important production mechanism. Initially, the solvent moves with the imbibing brine into the core. However, upon contact with oil, as the ...

COMSOL Multiphysics® software is used to model the field joint application process on carbon steel pipelines for deep sea crude oil transportation, taking into account not only heat transfer, cure kinetics, and crystallization, but also thermal, cure and crystallization shrinkage and the resulting interfacial thermal stresses. Experimental data from the raw materials are implemented in the model ...

Localized calcium events in the endothelial cells (EC) can modulate smooth muscle cell (SMC) calcium (Ca2+) and membrane potential dynamics through release of endothelium derived hyperpolarizing and relaxing factors. Ca2+ levels in the smooth muscle cell (SMC) determine its contractile state.The underlying complex mechanism regulating the SMC Ca2+ levels and ultimately vessel tone remains poorly ...
