Ar/H2 discharges are frequently used in various industrial applications, such as etching processes, surface treatment, and film deposition. In the discharges, the active species, such as ions and hydrogen atoms, are responsible for surface reactions, which could be considered as the ... Per saperne di più
We present numerical results involving microorganisms adhering to a plane surface submitted to a shear flow. The purpose is to have a better understanding of the removal mechanisms occurring during the cleaning in place of food processing equipments. The biological cell, i.e. the ... Per saperne di più
Heat transfer in a plane shear flow configuration consisting of two infinitely long parallel plates is considered. In laminar flows over undulated substrates eddies can be generated due to the kinematical constraints. A closed form analytical solution for the velocity field, based on ... Per saperne di più
We apply COMSOL Multiphysics for reproducing our experimental observations of fluid flow and transport processes in geological media. Our experimental GeoEPT-method allows the 4D monitoring of transport processes in geological material on laboratory scale. Explicitly we import ... Per saperne di più
Flow channel design in a PEM fuel cell plays a critical role for uniformly distributing reactants to the reaction sites and effectively removing product water to prevent flooding. Simplistic design and uniform reactant distribution make parallel channels a potential candidate for ... Per saperne di più
Microchannel heat sinks designed for applications in electronic cooling and having microscale heat transfer combine the attributes of high material compatibility, high surface area per unit volume ratios, and large potential heat transfer performance with a highly sophisticated and ...

Self-heating is a problem to consider for Ultrasound Imaging probes. Since the probe is in contact with the skin, it’s necessary to find a solution to lower the front face temperature in order to avoid patient discomfort, even at the most demanding operating condition. One solution ... Per saperne di più
In the Collaborative Research Centre 692 at TU Chemnitz several academic institutions work on aluminum matrix composites (AMCs). These materials consist of an aluminum matrix, which is reinforced by SiC or Al2O3 particles with dimensions less or equal 1 µm. One main task is finishing ... Per saperne di più
“页岩气革命”使美国成功摆脱了对他国能源的严重依赖,目前我国页岩气的勘探开发也已取得了突破性成果,但是随着页岩气的开发,仍存在三大问题困扰着科学工作者和现场工程师:(1)页岩气开发过程中的渗透率演化规律尚未摸清;(2)在产气过程中,页岩气在产量上往往呈现出不确定性;(3)缺乏针对页岩气进行历史拟合和产量预测的数学工具。针对以上三个主要问题,我们定义非常规储层固有渗透率的演化是裂隙和基质之间物质传输和应力传递的结果,并建立了离散体模型研究孔隙变形与流体流动之间的耦合作用;以此为基础,我们建立双基质双重孔隙介质模型(连续介质模型)研究页岩基质变形与流体流动之间的耦合关系 ...

This paper shows a model to estimate the scaling parameters for reverse osmosis membrane processes. The model takes into account the concentration polarization of ionic species in the membrane channel of spiral-wound modules and the effect of the spacers on the flow. The scaling ...
