Structure of a Classical Vortex Ring

J. M. Russell [1],
[1] Florida Institute of Technology, Melbourne, FL, USA

This talk is for users of the COMSOL Multiphysics® software who, like the present author, are relative newcomers to numerical simulation but have a strong grounding in Hydrodynamics or related areas of Mathematical Physics. As part of a multi-year plan to develop proficiency in Equation ... Per saperne di più

Numerical Simulation of Coupled Fluid-Solid Interaction in Digital Rock Samples

V. Das [1], T. Mukerji [1], G. Mavko [1],
[1] Stanford University, Stanford, CA, USA

Digital rock physics (DRP) is an emerging field where a rock sample is imaged, relevant physical processes are simulated numerically on the digital rock sample, and the numerical solutions are used for understanding and interpreting the rock in different in-situ conditions. The use of ... Per saperne di più

Multiphysics Simulation of 2nd Generation 238Pu Production Designs Using the COMSOL Multiphysics® software

C. J. Hurt [1], J. D. Freels [1], A. Elzawawy [2],
[1] Research Reactors Division, Oak Ridge National Laboratory, Oak Ridge, TN, USA
[2] Vaughn College of Aeronautics and Technology, East Elmhurst, NY, USA

In order to qualify experiments for in-vessel irradiation at the High Flux Isotope Reactor (HFIR) at Oak Ridge National Laboratory, safety assessments need to be completed and documented to ensure adequate target cooling and structural integrity. Previously, finite element analysis ... Per saperne di più

Modeling Two Phase Fluid Flow in High Speed Counter Current Chromatography

G. Stevens [1], K. Weisbrod [1], R. Chamberlin [1], S. Yarbro [1],
[1] Los Alamos National Laboratory, Los Alamos, NM, USA

High-speed counter current chromatography (HSCCC) is a unique process presenting possibilities for efficient separations by creating a large interfacial area between two phases in counter current flow. Millifluidic channels rotate about both planetary and solar axes to create a rapidly ... Per saperne di più

Mathematical Modeling of Drug Transport in Brain Tumors

Y. Guo [1], M. O. Bernabeu [2], C. D. Arvanitis [1],
[1] Georgia Institute of Technology, Atlanta, GA, USA
[2] University of Edinburgh, Edinburgh, United Kingdom

Blood-brain and blood-tumor barriers (BBB and BTB) constitute a major obstacle to the transport of therapeutics in brain tumors. Focused ultrasound (FUS), when combined with circulating microbubbles, provides a noninvasive method to locally and transiently disrupt the BBB/BTB. ... Per saperne di più

Improving Thermal Effect on Biological Tissue using Multiphysics Simulation and Shape Optimization

A. Ward [1],
[1] System Insight Engineering, Centennial, CO, USA

As minimally invasive and robotic surgical devices get smaller, designing precise energy delivery to create the desired tissue effect becomes a key component in product development. With many interdependent physical phenomena occurring simultaneously, it becomes necessary to use tools ... Per saperne di più
