This paper presents a study on the application of Direct Numerical Solving (DNS) techniques using an experimental scale model. COMSOL Multiphysics is promising in solving dynamic heat and air transport. The experiments can be extremely useful as benchmark for CFD codes. Per saperne di più
A dynamic mathematical model, based on physical and transport properties and mass and energy balances, was developed for the simulation of unsteady convective drying of agricultural products (fruits and vegetables) in static bed conditions. The model utilizes water sorption isotherm ... Per saperne di più
Binder jet printing (BJP) is one of the additive manufacturing methods that are being widely implemented as an efficient alternative for casting and machining in the automotive industry. Sintering densification of the as-printed part (green part) adds uncertainty and possible undesirable ... Per saperne di più
Microfluidics-based mixing has been widely used in various areas such as chemical engineering, biomedical engineering and materials science. The micromixer can be strategies into two categories as passive and active method depending on the mixing principle. Magnetic mixing integrated ... Per saperne di più
Laser-based powder bed fusion (LPBF) is a promising additive manufacturing technology, where metallic parts are produced in a layer-wise manner. At each step, a rapid-moving laser irradiates and subsequently melts predefined zones of a relatively thin layer of fine spherical metal ... Per saperne di più
In this paper, detail magnetostructural analysis of fusion grade superconducting toroidal field coils that are used in ‘tokamaks’ is presented. The stresses that arise due to Lorentz forces in large size superconducting coils that carry high currents are of catastrophic type in nature. ... Per saperne di più
城市内超高层建筑物的高度和密度的快速增加会影响城市风环境，城市风环境与人身健康、社会经济息息相关，然而目前缺乏针对超高层建筑物的高度和密度对风环境影响的定量研究。本文利用COMSOL Multiphysics® 5.2版本CFD模块中的湍流k-ε接口，采取控制变量法，数值模拟超高层建筑物不同高度和密度分别对应的城市风场，从高空风噪、阻挡作用、城市通风三个方面综合评价风环境质量，探索形成良好风环境的高度密度参数组合。研究结果表明，相邻两栋超高楼之间的高宽比小于0.89时，高空风噪、阻挡作用、城市通风都能较好地符合环境要求。 Per saperne di più
我国南海地区常年高温高湿、雨量充沛、太阳辐照强度大，风速大且风中包含大量水汽，处于多强场耦合的热带海洋环境下，建筑围护结构承受着远高于大陆地区的热湿压力。尽管我国已开始对南海地区进行开发建设，但尚无相应的建筑热工设计指标体系进行指导，使得热工选材无据可依，围护结构设计有所失真。作为指标体系建立的重要基础研究工作，探究极端热湿气候下围护结构热湿耦合传递特点具有重要的科学价值和实际意义。本文针对南海地区建立了一维瞬态热湿耦合传递模型，利用Comsol数学模块系数型PDE接口进行了求解，探讨了热量传递、水分传输过程中相关参数的变化特点 ... Per saperne di più
COMSOL Multiphysics software, when properly configured, can readily solve modeling problems in the laminar flow regime using the standard Navier-Stokes equations or in the fully turbulent flow regime using the kappa-epsilon model. Failure to solve a particular model is typically ... Per saperne di più
The most common method for in-situ recovery of oil sands is Steam Assisted Gravity Drainage (SAGD). SAGD is based on injecting pressurized steam into the ground to heat up the highly viscous bitumen and reduce its viscosity allowing oil to flow. This process is energy and emissions ...
