I introduce a model of fluidized reactor which, in presence of heterogeneous platinum-based catalyst, decomposes liquid formic acid producing gaseous mixture of carbon dioxide and hydrogen as the product. I treat the physical system as a (Class II) mixture of four constituents - namely ... Per saperne di più
Introducing a disorder into a finite periodic oscillatory system induces the presence of a 'trapped mode': a mode in which the displacement field is localised to the region of the disorder. A main inhibitor to MEMS resonators achieving a high quality (Q) factor is energy radiation ... Per saperne di più
We simulate a Capacitive Micromachined Ultrasound Transducer (CMUT) using COMSOL Multiphysics® software. The CMUT is an electromechanical system, therefore, we couple the physics of electrical and structural mechanics to describe its dynamics. We obtain the distributions of the electric ...

No processo Kraft a madeira é reduzida a uma massa fibrosa. Neste processo são rompidas as ligações entre as estruturas da madeira separando as fibras. Esta operação, denominada de polpação, é realizada em um equipamento denominado de digestor. Este trabalho analisa o comportamento ... Per saperne di più
Electromagnetic actuators are representing one important component of ABB's medium voltage reclosers [1, 2]. Their performance is strongly influenced by the considered material properties as well as by the electronic control units that will power the actuator. Depending on the studied ... Per saperne di più
A recurring problem, in heat assisted magnetic recording is the build-up of thermal energy in the near-field transducer leading to NFT deformation and the cessation of operation. A mechanism to dissipate this excess heat in the NFT without greatly effecting its’ plasmonic response is ... Per saperne di più
Abstract: As a environmentally friendly thermal energy harvesting device, thermoelectric generator (TEG) can convert heat into electricity directly. Therefore, researchers have made great efforts to detailed explanation the principium including established many steady-state models to ... Per saperne di più
隐伏地质构造是影响煤矿安全生产的主要因素，准确识别地质构造在槽波地质勘探研究中显得尤为重要，本文采用支持向量机的方法对槽波地质构造进行识别，首先用COMSOL仿真软件对采空区、冲刷带、陷落柱、小断层、褶曲5种不同地质构造进行模拟仿真，随后采集对每类地质选取了多个不同的测量点得出的仿真数据726组，预处理数据进行特征构建，分别进行时间分块方差统计、频域分块能量统计、时序信号总体的均值、方差、平均能量、最大最小值差统计。 接下来用支持向量机对不同地质构造进行识别，主要用到支持向量机回归，通过MATLAB编写SVM来对该分类问题的数据进行训练和预测 ... Per saperne di più
优先流作为结构性土壤水分入渗的主要方式，影响着作物对降水以及灌溉用水的利用效率，同时影响污染物在土壤中的迁移过程。虫洞等大孔隙是产生优先流的重要因素，准确评估优先流运动对于土壤入渗的研究具有重要意义。本文主要借助COMSOL Multiphysics软件，探索虫洞的存在对土壤水分入渗的影响。我们结合熔锡灌注法和三维激光扫描法，从田间土壤中提取到真实的虫洞三维结构，然后将真实的虫洞3D结构导入COMSOL5.5中，构建土壤入渗模型。该模型主要用到多孔介质和地下水流模块的理查德方程，其中土体主要由虫洞和土壤基质两部分构成 ... Per saperne di più
