Numerical Simulation of the Effect of Inlet Design on Thermal Storage Tank Performance Using COMSOL Multiphysics®

W. Yaïci[1], M. Ghorab[1], E. Entchev[1]
[1]Natural Resources Canada, CanmetENERGY, Ottawa, ON, Canada

This study presented the results of 3D unsteady CFD simulations to investigate the influence of adding a flat baffle plate at the entrance during the discharging operation on the flow behaviour, thermal stratification, and performance of a hot water storage tank installed in solar ... Read More

Acoustic-Structure Interaction Simulation of a Differential Phase Sensor

J. H. Lee[1]
[1]Department of Mechanical Engineering, American University of Sharjah, Sharjah, UAE

The idea of application as a hearing device based on a parasitoid fly, Ormia ochracea has been studied extensively recently. This paper addresses another possible application as an underwater directional sensor. In order to study the feasibility of the application, it is necessary to ... Read More

Numerical Modeling of Power Reactors' Fuel Bundles

R. Schmidt[1], T. Yousefi[2], B. Farahbaksh[2], M. Z. Saghir[2]
[1]University of Louisiana at Lafayette, Lafayette, LA, USA
[2]Ryerson University, Toronto, ON, Canada

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 ... Read More

Multiphysics Topology Optimization of Heat Transfer and Fluid Flow Systems

E. Dede[1]
[1]Toyota Research Institute of North America, Ann Arbor, Michigan, USA

This paper is focused on topology optimization of heat transfer and fluid flow systems for multiphysics objectives. Specifically, COMSOL Multiphysics software is coupled with a method of moving asymptotes optimizer in a custom COMSOL / MATLAB script. Various physical process including ... Read More

Optimized Channel Geometry of a Flow-Focusing Droplet Generator for Parallelization

D. Conchouso[1], E. Al Rawashdeh[1], D. Castro[1], A. Arevalo[1], I.G. Foulds[1]
[1]King Abdullah University of Science and Technology, Thuwal, Saudi Arabia

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 ... Read More

FEM Simulation for ‘Pulse-Echo’ Performances of an Ultrasound Imaging Linear Probe

L. Spicci[1]
[1]Esaote SpA, Florence, Italy

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): ... Read More

Studying Transition Flows for Low Prandtl Number Fluids

H. Jamai[1], A. Elamari[1], M. El Ganaoui[2], F.S. Oueslati[1], B. Pateyron [2], and H. Sammouda[3]
[1]LETTM, Département of physics, F.S.T, Tunisie
[2]SPCTS UMR CNRS, Faculte of Sciences, Limoges, France
[3]ESST-H., Sousse, Tunisie

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 ... Read More

Study of ER Non-equilibrium Behavior with COMSOL

L. Zhou
Fudan University, Shanghai, China

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 ... Read More

Pore-Level Influence of Contact Angle on Fluid Displacements in Porous Media

H. Ali Akhlaghi Amiri[1]
[1]University of Stavanger, Stavanger, Norway

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 ... Read More

Using Temperature Signals to Estimate Geometry Parameters in Fractured Geothermal Reservoirs

F. Maier[1], P. Oberdorfer[1], I. Kocabas[2], I. Ghergut[1], M. Sauter[1]
[1]Dpt. Applied Geology, Center of Geosciences, Georg-August-University, Göttingen, Germany
[2]Petroleum and Natural Gas Engineering Department Batman, Batman University, Batman, Turkey

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 ... Read More
