Introduction: We study an innovative technology for water bottling using PET, aimed at reducing the thickness of the plastic bottles. The goals are the reduction of the amount of plastic used for a single water bottle, the reduction of the packaging costs and more environmental sustainability. The required thickness of the bottle depends on its structural function: when carried, the bottles are ...

Introduction: Power electronic converters such as those for High Energy Physics Experiments (HEPEs) must operate in thermally hostile environment. Heat generated by electronics components must be conveniently dissipated to ensure electrical performances and improve reliability. Due to the high power density, the presence of closed environments, and the requirement of non-thermal interaction with ...

A scheme for inductive wireless powering and readout of passive LC sensor is presented. The sensor’s inductor is designed as a planar square coil and is used as the power receiving component. The capacitor is connected directly to the inductor and it was designed as an interdigital capacitor. With a transmitting coil (coupling antenna), an electromagnetic field is generated which couples with ...

Waterflooding and steam-flooding are used worldwide for EOR. Recently, CO2-flooding has attracted global attention as a means of EOR as well as for carbon capture and sequestration. These processes cause significant changes over time in the fluid composition of oil reservoirs. This paper demonstrates the feasibility of a borehole transient electromagnetic (TEM) system that can map the fluid ...

Introduction: Understanding the mass and charge transport behavior of heterogeneous systems that include diffusion, migration, and reaction of ions is important in fuel cells, batteries, and other electrochemical applications. Here, a numerical model for charged species transport and reaction has been developed to simulate the electrochemical behavior of a novel type of “non-flooding” hybrid ...

This paper describes the development of a COMSOL model of Electro-Chemical-Mechanical Planarization (ECMP) that was validated with experimental data. ECMP is used for processing of semiconductor wafers. We developed a 2D model of flow of phosphoric acid solution (the electrolyte) between two parallel plates that focuses on the physics and electrochemistry in ECMP. The model includes steady-state ...

Interstitial fluid pressure (IFP) is elevated in tumors. Owing to this elevated IFP, the interstitial fluid velocity (IFV) is negligible throughout the tumor but significant near the tumor margin. Any therapeutic strategy that can lower IFP will improve drug convection within the tumor and decrease convection of drugs from the tumor margin. High intensity focused ultrasound (HIFU) has been shown ...

In this work, we study the design of a new integrated system for Solar Water Heating that combines the solar thermal energy collection (primary circuit) with the heat storage (secondary circuit) into the same device. We have performed different finite element method simulations using COMSOL Multiphysics®, for solving the equations of heat transfer (conduction and convection) and those of fluid ...
