This publication aims to investigate conjugate heat and mass transfer around a clothed virtual manikin. This research can be performed at different scales: (1) at material scale where a piece of textile is investigated in 1D or 2D space or (2) at system level where a clothed cylindrical body (2D) or a complete manikin (3D) is modeled. The work is based on previous methods and results from ...

Nano patterning for chip manufacturing has reached its limitation with 193i lithography standard process. Directed Self Assembly (DSA) of Block Co-Polymers (BCP) is envisaged as an alternative complementary technique that can reduce critical dimension and pitch with high throughput and limited cost . For contact layers that require patterning of cylinders with diameter of tens nanometers, DSA ...
所谓近场声学，是相对于远场声学而言。传统的声学理论，通常只研究远离光源或者远离物体的声场分布，一般统称为远场声学。远场声学在原理上存在着一个远场衍射极限，限制了利用远场光学原理进行显微和其它光学应用时的最小分辨尺寸和最小标记尺寸。而近场声学则研究距离光源或物体一个波长范围内的光场分布。在近场声学研究领域，远场衍射极限被打破，分辨率极限在原理上不再受到任何限制，可以无限地小，从而基于近场声学原理可以提高显微成像与其它光学应用时的光学分辨率。 声学超材料自问世之日起就受到了国内外科学家们的广泛追捧，在很多领域都可以看到其踪迹，以声子晶体为代表的声超材料具有很多天然材料所不具备的声学特性，为声学信号处理带来了很多创新的思路和途径。 声超材料的突出特点在于采用尺寸远小于入射波长的人工结构构建出等效参数，利用等效参数实现“小尺寸结构调控大尺寸波长”的目的。 ...

Electrochemical flow cells have found widespread use in analytical chemistry due to their short response time, high sensitivity and selectivity. The geometrical flexibility and therefore, the ease of coupling the electrochemical to other experimental techniques has attracted considerable interest for applications in electrocatalytic research as well. Such coupling is far more cumbersome with the ...

Acoustic standing waves can be used to manipulate micrometer sized particles, cells and organisms. In most applications these objects are driven towards pressure nodal lines, predominantly by the primary acoustic radiation force. Interestingly, at intermediate particle concentrations, detailed phenomena of line-formation and inter-line repulsion occur. Such phenomena are believed to be caused by ...

This paper presents a multiphysics model to the convective, conductive and radiative heat transfer for the thermoelectric modules (TEMs), which are used to convert heat flux into electrical current. The model basically consists of heat transfer in solids, heat transfer in thin shells, surface-to-surface radiation and non-isothermal turbulent flow. The developed model has a good agreement with ...

This project makes a first attempt at modelling fluid flow over shark skin on a microscopic level. The modeled fluid flow shows good agreement with theory. Further refinement of the model parameters holds promises of better understanding of this complex fluid flow phenomenon. The COMSOL Multiphysics® model was evaluated against micro particle image velocimetry measurements of the same flow ...

Graphene, a single layer of carbon atoms, has demonstrated extremely high electric and thermal conductivities, tensile strength, and is therefore an exciting novel building block in the world of 2D flexible electronics. We propose the integration of graphene with MEMS devices to investigate the strain dependence on graphene material properties, such as electrical and thermal conductivity, index ...

Present study discusses a new method of how to apply numerical simulation in COMSOL Multiphysics® software to improve the accuracy of polymer melts viscosity measurements. The main emphasis is placed on evaluating the effects of entrance and exit geometry of a capillary rheometer on viscosity measurement. By combining experimental and COMSOL® simulation results, an accurate Bagley correction ...
