Heap leaching in the mining industry had become a sophisticated practice at least 500 years ago. It is a mineral processing technology whereby piles of crushed Run-of–Mine rock are leached with chemical solutions to extract minerals. The goal of this work is to contribute to the understanding of the behavior of a heap leach pad by using coupled Hydro-Mechanical-Chemical simulations. COMSOL ...

Magnetic Particle Imaging (MPI) is a new imaging technology based on the non-linear magnetisation of magnetic nanoparticles which can be used as a tracer material. In a high speed 1D MPI Device, a sinusoidal signal containing a single frequency generate a time-varying magnetic field via the drive coil. We propose to use a COMSOL Multiphysics® simulation to be able to calculate otherwise hard ...

SAFARI is a far-infrared imaging spectrometer for the Japanese satellite observatory SPICA. SAFARI covers the wavelength range 34—210 μm (1.4—8.8 THz) using Transition-Edge-Sensor (TES) bolometers. We have built a test facility to qualify and characterize the SAFARI focal plane units using cryogenic optical calibration sources. To support this work we have used COMSOL Multiphysics® to model the ...

A COMSOL Multiphysics® model of our apparatus has been created in order to simulate the pressurizations of our nanoparticles by Deuterium. Using reference measurements during a cooling process, we calibrated the model so that its thermal aspects reflect the ones of our experimental set up. To reproduce the pressurizations, the following variables are parameters : the location of the heat ...

Kheer is a popular Indian dairy dessert prepared from concentrating milk with simultaneous cooking of rice grains. Conventional methods of preparing kheer have limited its mechanized production. Therefore, a conceptual design of continuous kheer-making machine has been prepared which among other components consists of a heating section for cooking kheer. The present study investigates the CFD ...
Modeling of Noise Produced by Offshore Wind Turbines with Different Foundations and Effects on the Marine Environment - new

Vibration produced by offshore wind turbines during their normal operation transmits through the tower into the foundation where it interacts with the surrounding water and is released as noise. The noise produced by offshore wind turbines can be detected by fish and marine mammals and may lead to alteration of their behavior. Given that noise is emitted at the interface between the foundation ...

This study deals with the 3D modeling of a light photocatalytic textile. This process aims to decontaminate industrial effluents such as water with pesticides. The present study describes the implementation of a reactive transport model in a computational fluid dynamics model developed on a Representative Volume Element (RVE) of the textile, i.e. at the microscopic scale. The final ...
引言：为了不断地增加磁存储密度，机械硬盘中磁头和盘片之间的间隙，即飞高，已经减小到了 10nm 以下，以比特磁记录技术（BPM）和热辅助磁记录技术（HAMR）为代表的新兴技术不断涌现，给磁头磁盘界面的超薄气体润滑特性研究提出了新的挑战。 COMSOL Multiphysics® 的使用：由于在超薄气体润滑领域，连续介质模型已经不再适用，控制方程为玻尔兹曼方程。本文以 F-K 模型为控制方程，此模型是在线性玻尔兹曼方程和 BGK 方程基础上结合流量连续条件建立的修正雷诺方程。我们使用了 COMSOL Multiphysics® 中的 PDE 接口进行了自定义修正雷诺方程的建模，并利用参数化扫描进行不同参数影响的分析。利用LiveLink with MATLAB 接口编制磁头动力学方程，并进行方程的求解，得到磁头飞行的稳定飞行姿态。 结果：通过 COMSOL 的仿真计算 ...
