The main mechanisms of acoustic attenuation in a bundle of fibres typical of lightweight fibrous porous materials are the dynamic viscous drag forces on the surface of the fibres, and the thermal heat transfer between the solid fibres and the surrounding fluid. Microstructure models ... Mehr lesen
Slot coating is a widely used commercial process for applying one or more thin layers to a substrate such as paper, fabric, film or other material. In many cases, a highly uniform thickness is required, where a coating head that has been corrected for use with a Newtonian fluid may not ... Mehr lesen
The Electrical Double Layer (EDL) plays a major role in understanding the interface between a charged surface (e.g. an implant) and ionic liquids (e.g. body fluids). The three classical models of the EDL (Helmholtz, Gouy, and Chapman-Stern) are numerically solved for a flat surface ... Mehr lesen
We present examples of the use of COMSOL Multiphysics for the solution of electrical conduction in varistors coupled to the solution of long-term heat-transport through conduction and convection. We fit measured power-loss and impedance data with analytic functions in order to simulate ... Mehr lesen
Mice are important animals used for biomedical research, and are widely used to study various disease models. When studying the behavior of mice and gathering biological data from them, miniature sensors and telemetry devices are needed. These devices must provide continuous monitoring ... Mehr lesen
目前大部分研究集中于空气声学领域，水下声学超材料的报道相对较少。由于水的声学阻抗远大于空气，所以水下声学超材料的设计思路与空气中的相比有很大的不同。针对水下声学超材料，人们提出了一种声学软超材料的概念，即把密度或体积模量远小于水的材料填充在水介质中来构建超材料。然而如何有效且有实际应用价值地制备声学软超材料，仍然是一个难题。本工作通过结合3D打印和材料表面疏水性质，提出了一种制备以气泡为共振单元的超材料的通用方法。利用3D打印的方法制备表面疏水的镂空框架结构，将其浸没入水中后镂空框架中就会形成气泡。这种方法能实现水下三维气泡阵列的快速制备，气泡的形状、大小 ... Mehr lesen
A patch antenna based on metamaterials of composite split-ring-resonators (CSRRs) and strip gaps is designed with COMSOL Multiphysics® software. The antenna is constructed by using CSRR structures in forms of circular rings on the patch and employing strip gaps on the ground plane. The ... Mehr lesen
Developing a new loudspeaker design requires not only knowledge and experience in the field, but also an access to verified and efficient tools. HARMAN’s Virtual Product Development (VPD) team has developed a Comsol Application to serve at the early stages of the design process. The app, ... Mehr lesen
The technology involved in high performance ultrasound imaging probes needs a reliable model to help in new projects development and performance simulations. To achieve a useful model, it is necessary to use correct values for all material parameters involved in the electro-acoustical ... Mehr lesen
An Acoustic Vector Sensor (AVS) is a compact device used for finding azimuthal as well as elevation angle of an acoustic source using particle velocity and pressure measured at the acoustic center of the device. There are mainly two types of AVS; namely P-P and P-U based AVS. P-P based ... Mehr lesen
