Fuel bundles in the CANDU (CANada Deuterium Uranium) reactor are designed for heating a pressurized coolant (heavy water) to generate electricity. The designs for the fuel bundles differ based on the number of heating elements. The flow of heavy water over the elements and inside the ... 詳細を見る

This document presents the Computational Fluid Dynamics (CFD) simulation of a commonly used Microfluidic Droplet Generator (MFDG) using the Laminar Two-Phase Flow, Phase Field method in COMSOL Multiphysics®. The paper discusses the effect of the channel’s geometry in droplet size at ... 詳細を見る

Pulse-echo FEM simulation is seldom found in literature for ultrasound imaging array probes, since the complete modeling of such device is extremely complicated. Nevertheless, the 2D FEM described in the present work was successful, thanks to the following design procedure (see figure): ... 詳細を見る

COMSOL Multiphysics is offering an important alternative to home codes for modeling and simulation of complex problems with including coupled effects on heat and mass transfer. The present work focuses on low Prandtl number fluid melts subject to symmetry breaking and transition to ... 詳細を見る

The crystal growth industry uses high temperature processes. To improve production efficiency, a good knowledge of thermal effects is necessary. We show in this article a methodology to get reliable data by mixing simplified models, sensitivity studies and parameters adjustments. The ... 詳細を見る

We compare the output of 2D single fracture models as well as analytical solutions of the problem. The temperature signal is evaluated with the heat transfer mode while the flow field is assumed to exhibit Darcy flow everywhere. The problem is time-dependent so we have to take into ... 詳細を見る

COMSOL Multiphysics is a powerful tool in theoretical study. Lei Zhou, Jiping Huang and other professors in Physics Department, Fudan University have achieved some exciting results of soft, tunable metamaterials. We use it to study non-equilibrium behavior of rhoeological (ER) fluids and ... 詳細を見る

We address the use of magnetic fields, forces, and materials for medical purposes. In particular, the treatment of osteochondral lesions is aimed for. To support ongoing activities in this field of research, last advances in using Finite Element Analysis (FEA) for the simulation of ... 詳細を見る

In the Fluid Jet Method, a polishing fluid is compressed and delivered through a nozzle, allowing the spot area to become continuously replenished with abrasives and coolant. Process parameters include: Abrasive type and concentration, Inlet pressure, Nozzle diameter, Impingement angle, ... 詳細を見る

Wettability affects two-phase displacements in porous media by determining the microscopic distribution of fluids in pore spaces. The impact of wettability on transport properties at macro-scales has been widely addressed in literature; however a deeper understanding of wettability ... 詳細を見る
