In the molding industry, high productivity rate, low energy consumption, large 3D parts, and homogeneous temperature distribution are the main targets. The 3iTech® inductive technology developed by RocTool ensures both good temperature homogeneity and short heating time. Conventionally, to guarantee efficient cooling, a turbulent water flow is directly integrated into the mold. Ideally, to cope ...
A COMSOL Multiphysics® Software Analysis of Beam Tube Cooling in the High Flux Isotope Reactor of ORNL

 Research Reactors Division, Oak Ridge National Laboratory, Oak Ridge, TN, USA
Previous to the present work, a formal calculation was approved [1,2] to support the operation of the High Flux Isotope Reactor (HFIR) Horizontal Beam-Tube 1 of 4 (HB-1). The present calculation [3,4] repeats the previous work using COMSOL Multiphysics® software and extends the analysis to cover a broader range of coolant flow. In addition, this new calculation expands the analysis much further ...

Ventilation is mainly used to control indoor air quality and for the purpose of thermal comfort by diluting and displacing pollutants. Because of the effects it has on health, comfort, and serviceability, indoor air quality in our homes is becoming of increasing concern to many people. Many countries even push citizens to opt for energy conservation , energy savings buildings based on natural ...
作为一项重要的材料表面处理技术，抛光直接影响着材料表面粗糙度等表面质量评价参数。随着微纳技术和精密制造的发展，工业应用中对材料表面粗糙度的要求越来越高，对抛光技术的综合要求也随之越来越高。然而，一些传统抛光方法的弊端日益凸显，无法再满足工业需要。激光抛光作为一种非接触式抛光技术，避免了传统抛光技术的磨痕，作用区域可控，可以对选定的区域进行局部抛光，也可以对复杂结构、机械不可达或难接近结构进行抛光。本文基于传热学和流体力学的基础理论，利用多物理场耦合有限元软件 COMSOL Multiphysics®，建立激光抛光过程的热-流-自由液面变形有限元模型，分析了表面张力和 Marangoni 效应对自由液面变形的影响规律，阐明激光抛光的主导机制。

A 3-D model for compost was constructed taking as geometry basis a truncated cone, with dimensions of 4 m radius and 3 m height; in this structure an energy balance is applied for a two phase system (solid-air). Compost energy processes are modeled using COMSOL with a modified heat transfer equation which includes: volumetric heat capacity, chemical oxidation and biological growing and ...
Improvement of a Steady State Method of Thermal Interface Material Characterization by Use of a Three Dimensional FEA Simulation in COMSOL

An FEA model of a steady state thermal interface material characterization apparatus was created in COMSOL Multiphysics 4.2a. This model was then fitted using three convection heat loss coefficients and the conductance of the TIM layer to a set of experimental measurements made using a steady state apparatus. It was shown that the model successfully matched the measured temperature values and ...

Concentrated photovoltaic systems with high efficiency solar cells are being widely investigated, aiming at improving the cost-efficiency balance in the solar energy field. Different cell types are in use: e.g., high concentration triple junction cells, reaching efficiencies of the order of 35 - 40 % at 1000 suns, and medium concentration mono-crystalline silicon cells, with efficiencies of the ...

Tecnotion produces linear motors for the high tech automation and semiconductor markets. Orthocyclically wound coils give the best performance because the largest number of windings can be packed into a given volume, as opposed to "wild winding", where the windings fall where they may. Additionally, the anisotropic heat conduction perpendicular to the wire direction is optimized because each ...

There is a great need for an effective drug treatment of the posterior eye, as the major reason for visual disability in industrial countries is Age-related Macular Degeneration (AMD). In USA alone, there are almost 2 million people affected by AMD . A virtual pharmacokinetic 3D model of the human eye is built to address this problem, using COMSOL Multiphysics® software, based on the Finite ...

A thermo-physical 3D model of a commercial Li-ion battery was developed and validated. Visualization of the temperature distributions inside a Li-ion cell during cell stacking processes were simulated. Critical temperature levels depend on position, duration and intensity of the thermal stressing. Results show a maximum local temperature of 180 °C at the jelly roll after laser welding for 4 s ...
