This example considers the thermal cracking of acetone, which is a key step in the production of acetic anhydride. The gas phase reaction takes place under nonisothermal conditions in a plug-flow reactor. As the cracking chemistry is endothermic, control over the temperature in the ... 詳細を見る

This alternative version of the Tubular Reactor app demonstrates how computational speed can be significantly increased by using a surrogate model instead of a full finite element model. A surrogate model is a simplified, computationally efficient approximation of a more complex and ... 詳細を見る

Chemical engineering students can model a nonideal tubular reactor, including radial and axial variations in temperature and composition, and investigate the impact of different operating conditions with this easy-to-use app. The process described by the Tubular Reactor with ... 詳細を見る

All integrated circuits (ICs) — especially high-speed devices — produce heat. In today’s dense electronic system layouts, heat sources are many times placed close to heat-sensitive ICs. Designers of printed circuit boards often need to consider the relative placement of heat ... 詳細を見る

This model serves the purpose of validation and verification of the Linear Elastic Material, Layered model in the Shell interface. In COMSOL Multiphysics, composites are analyzed either based on Layerwise 3D elasticity theory through the Layered Shell interface or based on FSDT-ESL ... 詳細を見る

During an internal short circuit of a battery, the two electrode materials are internally and electronically interconnected, giving rise to high local current densities. Internal short circuits may occur in a lithium-ion battery due to, for instance, lithium dendrite formation or a ... 詳細を見る

Graphene, carbon atoms arranged in a two-dimensional hexagonal lattice has sparked tremendous research and application interests since its experimental discovery about two decades ago. Besides being ultrathin, this material exhibits a plethora of interesting properties, including high ... 詳細を見る

ヒートパイプは, 作動流体の気化, 物質移動, 凝縮を通じて熱を効率的に伝達するように設計されています. ヒートパイプは, 電子機器の冷却など, 熱制御が重要となるさまざまな用途で使用されています. ヒートパイプ内部では, 高温側と低温側の温度差と蒸気圧の温度依存性により, 蒸気室全体に圧力差が生じます. この圧力差により, 蒸気は高温側から低温側へと移動します. 高温側では, 蒸発が蒸気-ウィック界面でヒートシンクとして機能し, 逆に低温側では凝縮が熱源として機能します. このモデルは, ... 詳細を見る

In this tutorial, the acoustic properties of a wax guard are analyzed. A wax guard is a small perforated mesh used to protect the receiver (the miniature loudspeaker in a hearing aid) used for receiver-in-the-ear (RITE) or receiver-in-canal (RIC) hearing aids. Because of the very small ... 詳細を見る

This tutorial studies the propagation of high intensity focused ultrasound (HIFU) though a tissue phantom. HIFU is used in many different biomedical applications such as thermal ablation of tumors, transcranial HIFU surgery, shock wave lithotripsy, etc. A HIFU transducer typically ... 詳細を見る
