Modeling Drug Release from Materials Based on Electrospun Nanofibers

P. Nakielski[1], T. Kowalczyk[1], T.A. Kowalewski[1]
[1]Institute of Fundamental Technological Research Polish Academy of Sciences, Warsaw, Poland

Comprehensive studies of drug transport in nanofibres based mats have been performed to predict drug release kinetics. The paper presents our approach to analyze the impact of fibers arrangement, one of the parameters varied in our parallel experimental studies. COMSOL Multiphysics® has ... Read More

Modeling Deep-Bed Grain Drying Using COMSOL Multiphysics®

J.G. Pieters[1], R. ElGamal[1], F. Ronsse[1]
[1]Faculty of Bioscience Engineering, Department of Biosystems Engineering, Ghent, Belgium

CFD simulations were carried out to predict the convective heat and mass transfer coefficients in the rice bed, and correlations were developed for the convective heat and mass transfer coefficients as a function of drying air flow rate. The developed correlations were used to extend the ... Read More

Metal Foam Tube Flow Characterisation

T. Spillmann[1]
[1]CSIRO, Energy Technology, Newcastle, New South Wales, Australia

In this study the flow through a tube filled with highly porous aluminium foam of three different pore sizes is analysed using COMSOL Multiphysics® CFD Module and compared to experimentally determined pressure drop data. Analyzing the flow through an array of pores allow the deduction of ... Read More

Laser-Ultrasonics Wave Generation and Propagation FE Model in Metallic Materials

A. Cavuto[1], G.M. Revel [1], M. Martarelli [2], F. Sopranzetti [2]
[1]Università Politecnica delle Marche, Ancona, Italy
[2]Università e-Campus, Novedrate (CO), Italy

A 2D axisymmetric model was considered in order to evaluate the propagation paths of the ultrasonic waves generated inside an aluminum plate sample due to a rapid thermal expansion produced by laser pulse. Laser Doppler Vibrometer is used to experimentally validate the numerical results ... Read More

Lamb Waves in Fluid-Loaded Plates

T. Kaufmann[1], F. Kassubek[1], D. Pape [1], M. Lenner[1]
[1]ABB Corporate Research, Baden-Dättwil, Switzerland

Lamb waves are elastic waves propagating in free solid plates. In the case of plates loaded with a fluid, the equations describing these waves have to be modified to include the effects of the fluid. In our work we have tackled this problem using COMSOL Multiphysics®. We have used the ... Read More

Investigation on Sensor Fault Effects of Piezoelectric Transducers on Wave Propagation and Impedance Measurements

I. Buethe[1], C.-P. Fritzen[1]
[1]University of Siegen, Institute of Mechanics and Control Engineering-Mechatronics, Siegen, Germany

For active Structural Health Monitoring (SHM), one popular sensor type is the piezoelectric wafer active sensor (PWAS) due to its multi-purpose application as actuator and sensor and its low cost. It is used to generate a wave field, which interacts with the structure and is recorded by ... Read More

Investigation on an Encircling Pulsed Eddy Current Probe Performance Using COMSOL Multiphysics®

S. Majidnia[1], R. Nilavalan[1], J. Rudlin[2]
[1]Brunel University, London, United Kingdom
[2]TWI ltd, Cambridge, United Kingdom

Conventional eddy current techniques have been used to a great extent for detection of surface breaking defects in conductive materials. However, detection of sub-surface defects is limited due to the single frequency and skin effect phenomena. Pulsed Eddy Current (PEC) techniques ... Read More

Integrated Solar Thermal Collector with Heat Storage

A.R. Sánchez-Guitard[1], E. Ruiz-Reina[1]
[1]University of Málaga, Málaga, Spain

In this work, we study the design of a new integrated system for Solar Water Heating that combines the solar thermal energy collection (primary circuit) with the heat storage (secondary circuit) into the same device. We have performed different finite element method simulations using ... Read More

Influence of Thermal Conductivity and Plasma Pressure on Temperature Distribution and Acoustical Eigenfrequencies of High-Intensity Discharge Lamps

J. Schwieger[1], B. Baumann[1], M. Wolff[1], F. Manders[2], J. Suijker[2]
[1]Heinrich-Blasius-Institute of Physical Technologies, Hamburg University of Applied Sciences, Hamburg, Germany
[2]Philips Lighting, Turnhout, Belgium

High-intensity discharge (HID) lamps are energy-efficient light sources with excellent color qualities. A three-dimensional model of a low-wattage lamp, which includes plasma, electrodes, and burner walls, was developed in COMSOL Multiphysics®. Most parameters appearing in the coupled ... Read More

Influence of the Atmospheric Disturbance on the Respiration of a Forest Soil

C. Wylock[1], S. Goffin[2], M. Aubinet[2], B. Longdoz[3], B. Haut[1]
[1]Université Libre de Bruxelles (ULB), Transfers, Interfaces and Processes (TIPs), Brussels, Belgium
[2]University of Liège-Gembloux Agro-Bio Tech, Unit of Biosystem Physics, Gembloux, Belgium
[3]INRA, Centre INRA de Nancy, UMR1137 Ecologie et Ecophysiologie Forestières, Champenoux, France

The assessment of forest soil respiration and its isotopic composition is one of the important issues for the carbon cycling modeling (greenhouse gas emission control) because it is often inaccurate. Soil respiration is a complex process, depending on the coupling of several phenomena, ... Read More
