The main objective of this study is to verify the compliance of an ongoing nuclear facilities stack design with the ISO 2889 requirements, during normal and off-normal conditions. In particular, with the numerical simulations, they have been identify well-mixed sample locations along the ... Read More
The primary aim of using jet as mixer, like in case of other mixing devices, is to increase the heat and mass transfer between the phases. Beside the injection position the geometry of the jet mixer and the injection nozzle has a major effect on the injection. In our study COMSOL ... Read More
In the paper, first a basic concept of the engineering approach for modeling and control of distributed parameter systems (DPS) based on interpretation of controlled systems as lumped input and distributed output systems (LDS) is introduced. Next, FEM modeling of temperature fields in ... Read More

High levels of Indoor Air Quality (IAQ) in Operating Theatres (OT) is an important issue in order to contribute in prevention of Surgical Site Infections (SSI). Despite of specific plant layouts are applied for OT ventilation (e.g. unidirectional flow), the effective use conditions can ... Read More
An industrial pulp screen is investigated. The dilute pulp is pumped through a screen barrier. In order to avoid the fiber network to plug, it is necessary to 1) fluidize the shear thinning pulp 2) expose the barrier with plug releasing pressure pulses. This work involves a 2-step ... Read More
The aim of this work is to present a model capable to describe the behaviour of a thermal flow sensor under every physical aspect. A generic thermal flow sensor relates the flow properties with a variation in the temperature profile inside the device itself. Thus, it is locally heated ... Read More

晶粒细化可有效减少金属凝固组织内部缺陷、提升产品质量。在钢铁冶金领域，通过脉冲磁场干预金属凝固过程以促使凝固组织发生细化是一类常见的手段。近年来人们针对脉冲磁场细晶机制提出诸多机理，为了揭示哪种或哪些机理起主要作用，有必要对脉冲磁场作用下金属熔体内部电磁效应进行研究。本文利用COMSOL Multiphysics中的磁场、流场（k-ε）和动网格技术，对模铸和连铸条件下脉冲磁场在圆柱形金属熔体内产生的磁场、感应电流、电磁力和流场进行仿真模拟研究。研究揭示了电磁场随时间演变规律，以及熔体在电磁力作用下的流动规律。研究表明磁场主要以竖直分量为主 ... Read More
摘要：本文通过数值模拟分析研究了高效空气过滤器的阻力与PPI、滤纸褶高之间的关系。研究表明，在一定条件下，增加PPI和增加滤纸褶高都可以增大过滤面积，减小滤纸阻力，但同时会增大高效空气过滤器结构阻力，因此滤纸存在最佳的PPI或褶间距和褶高使过滤器的阻力最低。不同的滤纸有不同的最佳结构参数。本文采用数值模拟方法对高效过滤器的阻力进行模拟，经与实测数据对比表明，误差低于10%，模拟方法可行。同时，通过对某款滤纸制成的高效过滤器进行了模拟分析，讨论了PPI和褶高对高效过滤器阻力的影响。最后建立了通用数值分析方法，通过更改相关设定参数，快速计算高效过滤器的阻力 ... Read More
