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 ... Per saperne di più
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 ... Per saperne di più
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 ... Per saperne di più
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 ... Per saperne di più
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 ... Per saperne di più
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 ... Per saperne di più
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 ... Per saperne di più
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 ... Per saperne di più
Chemically driven actuators capable of directional motion have attracted considerable attention for their autonomy, sustainability, and versatility[1]. However, conventional enzyme-based actuators often suffer from limitations such as high cost and insufficient control over orientation. ... Per saperne di più
新能源汽车电池热失控特征极大关系着电池的安全边界，本文通过建立单体NCM电池的一维产气反应动力学耦合三维传热几何仿真模型，对电池热失控期间的温度，膨胀力特征进行分析。在COMSOL Multiphysics中先依据电池尺寸建立电池三维几何模型，电池结构为长方体热源，不额外考虑电池极耳的发热功率，将电池视作导热系数各向同性的集总热模型，之后在几何模型的基础上建立一维副反应动力学模型，利用偏微分方程接口模块实现实现电池热失控副反应产热量的计算，最后利用固体传热模块完成电池温度与产热的耦合，并输出相对应的膨胀力数值。通过完成验证的热失控模型，针对热滥用情况中的SOC ...
