We present quantitative nano-scale analysis of the 3D spatial structure of an anticorrosive aluminium epoxy barrier marine coating obtained by ptychographic X-ray computed tomography (PXCT) [1-3]. We then use COMSOL Multiphysics® software to perform simulations on the acquired real 3D ... 詳細を見る
In the core of Chemical Engineering is the reactor design that includes most of all scientific disciplines. The reactors, in general, are treated ideally. Unfortunately, it is observed in the real world a very different behavior from that expected. Thus, to characterize nonideal ... 詳細を見る
The objective of this simulation effort is to develop a mathematical model of vacuum desorption on a POC (Proof of Concept) canister loaded with Zeolite 13X/5A . This canister contains a pelletized adsorption bed which is used to adsorb H2O and CO2. Once this bed is fully saturated with ... 詳細を見る
One can hardly get the exact analytic solution of a full time-dependent convection-diffusion equation, for describing the dynamics of a non-premixed flamelet. The analytic solution of the linearized form with such a model was studied by MATLAB®. And also, a numerical computation was made ... 詳細を見る
Iodine absorber is a widely used purification equipment for purifying air in a nuclear power plant. In China, the common type is Ⅱ iodine absorber. Impregnated activated carbon is the main absorber within the iodine absorber. Because of the decays exothermic of radioactive iodine, heat ... 詳細を見る
Mathematical description of microwave drying requires the solution of two different physics: electromagnetics in the microwave oven cavity and food material and, transport process (mass, momentum and heat transport) in the food material. Maxwell’s equations for electromagnetics were ... 詳細を見る
Introduction: Singlet oxygen (¹O₂) has a critical role in the cell-killing mechanism of photodynamic therapy (PDT). Therefore, in this study, the distance-dependent reacted ¹O₂ is numerically calculated using finite-element method (FEM). Herein, we use a model [Ref. 1] that has been ... 詳細を見る
Proton Exchange Membrane (PEM) fuel cells are quickly becoming an attractive technology due to their ability to meet increasing energy demands in a cleaner, more efficient way compared to existing methods. A fuel cell is an electrochemical device which converts the chemical energy of a ... 詳細を見る
在可再生能源需求不断增长的背景下，本研究探索了一种新型的湿气发电（Moisture Electricity Generation, MEG）技术。这项技术利用地球上最丰富的资源——水，为环境友好型能源泛在获取开辟了新途径。然而，MEG器件内部的理化过程相当复杂，难以直观分析【2】。为了克服这一挑战，本研究采用了COMSOL Multiphysics®软件进行模拟仿真，以量化阐释这些复杂的动态理化过程。 集成仿真模型结合了多孔介质流、化学反应工程和电磁模块，通过耦合Richards方程、Nernst-Planck方程和Poisson方程 ... 詳細を見る
本工作提出一种双螺旋微波辅助生产生物柴油反应器来克服现有大规模连续流微波加热的局限性。基于隐函数、水平集和任意拉格朗日-欧拉公式（ALE）的算法，建立了一个关于微波加热、化学反应工程和流体搅拌流动的综合模型，通过流动连续性一致对使速度连续。在此模型中甲醇和油酸的摩尔比为6:1，以浓硫酸为催化剂，反应过程中所用的材料参数是关于反应溶液组分和温度的双变量函数。利用该模型，计算了加热过程中管道内部混合溶液温度、生成的油酸质量分数以及反应速率。 詳細を見る
