Optimizing Design of Soil Mixing Equipment through COMSOL Multiphysics® Simulations

T. Qiu[1], W. C. Kogelmann[2], K. Talebi[3]
[1]Department of Civil and Environmental Engineering, The Pennsylvania State University, University Park, PA, USA
[2]Alpine Sales & Rental Corp./Alpine Equipment LLC, State College, PA, USA
[3]Department of Energy and Mineral Engineering, The Pennsylvania State University, University Park, PA, USA

Soil mixers are widely used to mix biochemical agents and additives to remediate contaminated soils or drill cuttings and sludges. Through COMSOL Multiphysics simulations, this paper aims to evaluate the effect of geometric configuration of the blades and rotational speed on the mixing ... En savoir plus

Optimizing Inductor Winding Geometry for Lowest DC-Resistance using COMSOL Multiphysics® with LiveLink™ for MATLAB®

H. Schneider[1], T. Andersen[1], J. D. Mønster[1], M. P. Madsen[1], A. Knott[1], M. A. E. Andersen[1]
[1]Technical University of Denmark, Lyngby, Denmark

An optimization routine is presented to optimize a hybrid winding geometry for a toroid inductor in terms of the DC-resistance. The hybrid winding geometry consist of bended foil pieces connected through traces in a PCB. MATLAB® is used to create a GUI that visually plots the winding ... En savoir plus

Modeling Bioelectrochemical Systems for Waste Water Treatment and Bioenergy Recovery with COMSOL Multiphysics®

T. Oyetunde[1], D. Ofiteru[1], J. Rodriguez[1]
[1]Masdar Institute of Science and Technology, Abu Dhabi, United Arab Emirates

Most conventional wastewater treatment processes are quite energy-intensive. Global wastewater production is increasing due to growth in population, industrialization, and urbanization, creating an urgent need for energy-efficient wastewater treatment technologies. Moreover, waste ... En savoir plus

Finite Element Analysis of BAW Sensor

M. Hashiguchi[1], Y. Sumiyoshi[1]
[1]Keisoku Engineering System Co., Ltd., Tokyo, Japan

Achieving passive device working over two GHz bands for next generation mobile phone has been strongly desired. This paper investigated the spurious mode suppression for the BAW resonator. The border-frame technique which has been proposed in many literatures is examined here ... En savoir plus

Flow-induced Vibrations of the Uvula and its Implication on Snoring

J. Xi[1], Q. M. Mohamad[1], Y. E. Yuan[1], J. Rohlinger[1]
[1]Mechanical and Biomedical Engineering, Central Michigan University, Mount Pleasant, MI, USA

Flow-induced uvula deformation considerably altered the flow dynamics inside the nose. For a weak soft palate, complete flow occlusion can occur (sleep apnea). Vibration of the airway structures is crucial to better understand snoring generation mechanisms and breathing-related ... En savoir plus

A Multiphase Porous Medium Transport Model with Distributed Sublimation Front to Simulate Vacuum Freeze Drying

A. Warning[1], J. M. R. Arquiza[1], A. K. Datta[1]
[1]Cornell University, Ithaca, NY, USA

A continuum, porous medium formulation with non-equilibrium sublimation was developed and validated for freeze drying without and with uniform microwave volumetric heating. The model incorporates the effect of Knudsen flow at low pressure and low permeability freeze drying. The ... En savoir plus
