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 ...

Electron beam has a wide range of applications in the material processing and joining techniques. Apart from that, it has also been utilized to simulate steady as well as transient fusion reactor relevant heat loads. Transient heat load events spontaneously occur in the fusion reactor. Several hundred megawatt of power is dumped upon the plasma facing material surfaces for a very short ...
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 ...

Optimization of a typical electrochemical system with insulating shields is considered in this work, which objective is to reduce the current peak due to singularity and smooth the current density distribution along electrode surface. Moving mesh method was adopted to allow change in design variables, i.e., position and width of the insulating shields. It was found that combining optimization ...

Interfacial structures/pattern, especially with small-scale dimensions, are important to the chemistry of materials in determining the optical, electrical, mechanical, or other physical properties of novel materials. Polymers are often used for surface patterning. The diversity, the relatively low cost, the convenient mechanical properties and the compatibility with most patterning techniques ...
