Ground freezing techniques using liquid nitrogen are commonly used in order to increase the mechanical properties of the soils. This article presents a new ground heat exchanger using aluminum to increase the effective radius of the heat exchanger. Simulation results indicate that the ... Per saperne di più
The paper studies the thermal modeling and simulation of photovoltaic cells suitable for use in highly concentrated solar flux (> 1000 suns). The cells studied are those of GaAs kind. These cells are a very good alternative to be studied instead of more complex multi junctions cells. ... Per saperne di più
Multi-Scale and Multi-Dimensional (MSMD) modeling approaches have been proposed to simulate the thermal, electrical distributions and concentration behaviors of large size pouch cell. This approach is based on coupling of the energy balance with the Newman’s electrode model. Newman’s 1D ... Per saperne di più
The use of a reaction sphere as an actuator used by satellite Attitude Control System was proposed over twenty years ago. In principle this concept assumes the use of a single reaction sphere which can be accelerated in any direction instead of a set of reaction wheels. The solution ... Per saperne di più
One of the methods to recover oil from medium and low viscosity in complex reservoirs uses air injection leading to oil combustion. In this case the oxygen in the air burns the heavier components of the oil, generating a heat wave leading to vaporization of lighter components. The ... Per saperne di più
Ultra-thin chips of less than 20µm become flexible, allowing integration of silicon IC technology with highly flexible electronics. This combination allows for highly intelligent products of unprecedented thinness, flexibility and cost. Examples include sensor systems integrated into ... Per saperne di più
We theoretically studied the microwave coplanar line of different geometry based on MgO substrate with a thin (30 nm) ferroelectric layer under the external electric field using the environment of 3D modeling in COMSOL Multiphysics®, RF Module, Frequency Domain. Frequency dependence of ... Per saperne di più
The purpose of this work is to show whether an important difference in Lithium solid concentration and electrolyte concentration can be observed in a Lithium-ion battery model, when considering either the Butler-Volmer kinetics or the Tafel kinetics for describing the electrode kinetics ...

COMSOL Multiphysics® is used to simulate a thermal transport based flow sensor, which will be embedded in a micro-channel of a Poly-methyl methacrylate (PMMA) based microfluidic device. The channel height is 100μm and for simulation purposes the lengths has been set to 1.2mm. The heater ... Per saperne di più
Auxiliary Power Units can play an important role in reducing vehicle emissions, especially in diesel and kerosene driven vehicles. In conventional vehicles the electricity supply comes from a generator that is directly coupled to the propulsion engine. New generation of fuel cell APUs ... Per saperne di più
