Understanding the interactions between microbubbles and surfaces is key to the successful deployment of microbubbles in a range of applications. Two important examples are their use as a drug delivery mechanism, and their potential use of acoustically-driven bubbles as microscale sensors. Drug delivery with bubbles involves sonication at high frequency close to a boundary, and sensing with ...

The reduction of energy consumption in the building sector (nearly 40% of the energy consumption in Europe) is a real challenge to achieve the objective of the “2020 European climate and energy package”. In recent years, great interest is observed for the Stirling thermoacoustic machines. Nonlinearities due to the high level of acoustic pressure generate DC flows that are superimposed on the ...

The ear doesn’t solely listen but it also speaks. Sounds formed in the inner ear which are measurable in the outer ear are called Otoacoustic emissions (OAEs). Some claim these are produced by the outer hair cells (OHCs), the amplifiers in the inner ear. Our hypothesis is that the OHCs only amplify distortion products (DPs) but do not produce them.

Free convective fluid flow and heat transfer in cavity domains has received considerable attention over the past few years and the importance of this problem is due to the broad spectrum of industrial applications and environmental situations. The aim of this study is to investigate the effect of Darcian free convective heat transfer in a square cavity partially filled with porous media with ...

The fixed beds have the advantage of large heat transfer area, for they are used in some designs of innovative nuclear reactors as the reactor FBNR. Inside of study of fixed beds is important to define the following parameters: flow minimum and velocity profile of cooling fluid, temperature profile of cooling fluid and the fuel elements.

SOFC is a high temperature electrochemical device known for its fuel flexibility. Apart from using pure hydrogen, it can utilize CO (carbon monoxide), CH4 (methane) or any other higher hydrocarbon. Since methane is highly researched hydrocarbon fuel, it was chosen to start with. The most prominent problem faced while using hydrocarbon fuel in SOFC is the formation and deposition of carbon on the ...

Electrodermal Activity (EDA) is a measure of changes in the conductivity of the skin. It has have been found to be indicative of the individual’s autonomic nervous activity which is correlated to their stress and emotional state. These conductivity changes are tracked by injecting a small electric current directly into the skin and measuring the induced voltage drop over time. With increase in ...

Necrosis of human tissue can typically be obtained by exposure to temperatures below 40°C or above +50°C. However, inherent variability in tissue properties, the complexity of tissue response and dissipation of thermal energy by local perfusion or blood flow can make the development of routine, predictable in-vivo approaches to produce necrosis difficult. Although a number of thermal ablation ...
我们分别使用一个 2D 等离子体射流模型和一个 1D 放电模型来研究了脉冲等离子体射流中 OH 自由基的产生机理。对处于空气环境下的等离子体射流，我们发现产生 OH 自由基的反应主要有 H2O 的电子碰撞电离，H2O+ 的电子中和以及 H2O 被 O（1D）分解。其中 H2O 的电子碰撞电离所占比例最大。工作气体中额外的 N2，O2，空气和 H2O 使得管外的 OH 自由基密度有了少量提升，这也是由Penning电离产生的更多的电子引起的。另一方面，所增加的 O2 和 H2O 也大大增加了管内 OH 的密度，这分别是由于O（1D）浓度和 H2O 浓度的上升。在脉冲关闭时，气流将会把大量的 OH 自由基输送出管道。结果还表明脉冲数可以有效的控制等离子体的化学反应。所得实验结果得到了由激光诱导荧光测量的支撑，也同大气压等离子体在医疗、医药和材料加工行业的多种应用有关。

We have developed a model for computing current and field distributions in multifilamentary superconducting thin films subjected to the simultaneous effects of transport ac current and applied dc field perpendicular to the sample. The model is implemented in COMSOL’s PDE module (general form) and solves Maxwell equations using a highly non-linear resistivity to describe the superconductor ...
