Kinetics of Proteins in the Blood-Brain Barrier

K. Gandhi [1],
[1] University of California, Riverside, CA, USA

The delivery of chemotherapy for cancer into the central nervous system, in particular the brain, remains a challenge. This results in brain metastases commonly being a cause of death from cancer. Here, we look at the environment of the blood-brain barrier. Then, we explore two proteins ... Read More

Thermal Analysis of Dry Type Power Transformer under Effect of Linear and Nonlinear Loads

R. G. Mafra [1],
[1] Universidade Federal de Itajubá, Itajubá, MG, Brazil

The thermal performance of the dry type power transformers is directly connected to the internal heat source caused by electrical losses. Thus, it is necessary to evaluate the temperatures reached by the transformer core to ensure optimum operation. This paper presents a detailed ... Read More

Heat Generation Breakdown of Lithium-ion Batteries

WeiDong Fu [1], DongYou Wang [1], ZhiJun Qiu [1]
[1] Contemporary Amperex Technology Co., Limited, Ningde, China

The thermal behavior of lithium ion batteries could be investigated by efficient simulation method [1,2]. Here, we developed an electrochemical-lumped thermal analytical model to analyze the thermal response and heat breakdown of a pouch LiNi1/3Co1/3Mn1/3O2 battery (3Ah) under fast ... Read More

Modeling, Simulation, and Optimization of Piezoelectric Bimorph Transducer for Broadband Vibration Energy Harvesting in Multi-Beam and Trapezoidal Approach

N. Chen [1], V. Bedekar [1],
[1] Department of Engineering Technology, Middle Tennessee State University, Murfreesboro, TN, USA

The objective of the research is to design a broadband energy harvester device through the multi-beam approach and non-linear trapezoidal geometry approach. The performance of two piezoelectric PZT-PZN polycrystalline ceramic composition samples are simulated in COMSOL Multiphysics®, and ... Read More

Sensitivity Analysis of CPP’s for Solvent Removal Process of a API-Protein Bonded Nano-Suspension

C. C. Huang [1], T. Liu [1], F. Faassen [1],
[1] Teva Pharmachemie B.V., Haarlem, The Netherlands

Solvent extraction and evaporation is a widely used unit operation in the manufacturing of micro and nano-particles. Due to the weak bond of the API to the protein, the product is highly sensitive to temperature, mechanical mixing and extraction/evaporation rate. A slow extraction ... Read More

Optimization of an Explosive Mixture Cooling Process Including a Phase Change

J. D. Wheeler [1], P. Namy [1], C. Coulouarn [2], E. Benade [2],
[1] SIMTEC, Grenoble, France
[2] TDA Armements, LA-FERTÉ-SAINT-AUBIN, France

In the scope of improvement of the industrial “ammunition cooling” process, a COMSOL Multiphysics® model is developed to transfer an existing cooling process. A device filled with a liquid explosive mixture is placed in an apparatus which controls the environment temperature. This ... Read More

Simulation of a Vortex Ring: Dealing with the Unbounded, Doubly Connected Domain

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

This talk is for intermediate-level users of COMSOL who, like the present author, are relative newcomers to numerical simulation but have a strong grounding in Hydrodynamics or related areas of Mathematical Physics. Most turn-key Computational Fluid Dynamics packages, including COMSOL ... Read More

Multiphysics Modeling and Development of Automotive Heat Exchanger for Exhaust Heat Recovery

Asutosh Prasad [1], Raj CN Thiagarajan [1],
[1] ATOA Scientific Technologies Pvt Ltd, Bengalore, Karnataka, India

An Internal Combustion Engine (IC Engine) is a heat engine where combustion of air-fuel mixture occurs in a combustion chamber. The combustion of chemical fuels produces energies in form of heat and pressure. The pressure energy then converted to mechanical work through piston, ... Read More

Coupled Optical and Thermal Modeling of Novel Solar Thermal Collectors

A. Hassanzadeh [1], Y. Bhusal [1],
[1] University of California - Merced, Merced, CA, USA

In the present study, the performance of the two novel solar thermal collectors are modeled using COMSOL Multiphysics. Firstly, Parabola and seagull geometries are utilized as primary and secondary reflector with high concentrator(50X) for high temperature application (650°C). Secondly ... Read More

COMSOL Multiphysics Models for Teaching Chemical Engineering Fundamentals: Absorption Column Models and Illustration of the Two-Film Theory of Mass Transfer

W. Clark
Chemical Engineering Department, Worcester Polytechnic Institute, Worcester, MA, USA

COMSOL® models have been developed for teaching gas absorption fundamentals. Model results are compared to environmentally significant experimental results for removing CO2 and SO2 from air using water as solvent. For concentrated gas mixtures, the models are shown to be equivalent ... Read More
