Inverse Problem and a New Device to Estimate Thermal Conductivity of Composite Phase Change Material

M. Karkri [1], A. Nachaoui [2]
[1] Université Paris-Est, CERTES, Créteil Cedex, France
[2] Département de Mathématiques 2, Nantes Cedex, France

A new experimental device has been developed in order to characterize the phase change material (PCM) thermal properties (thermal conductivity k, sensible and latent heat thermal energy storage, cp and Lf) in the solid phase, during the solid-liquid transition and in the liquid phase. It ... Mehr lesen

Calculation of Surface Acoustic Waves on a Piezoelectric Substrate using Amazon™ Cloud Computing

U. Vogel [1], M. Spindler [1], S. Wege [1], T. Gemming [1]
[1] Leibniz Institute for Solid State and Materials, Dresden, Germany

In this work, we seek to simulate SAWs for a better understanding and to benchmark the currently available cloud computing possibilities of COMSOL Multiphysics® software. By using the MEMS module we demonstrate 3D models with reduced geometry to achieve principle information about the ... Mehr lesen

Remote Sensing of Electromagnetically Penetrable Objects: Landmine and IED Detection

R. Eze [1], G. Sivulka [2], ,
[1] City University of New York - LaGuardia Community College, Long Island City, NY, USA
[2] Regis High School, New York, NY, USA

The detection, characterization, and classification of underground environmental hazardous objects [mines, IEDs, and other unexploded military hardware] is a worldwide problem that needs urgent attention and solution. While electromagnetic sensor technologies have been applied to ... Mehr lesen

Novel Approach for Teaching Microchemical Systems Analysis to Chemical Engineering Students Using Interactive Graphical User Interfaces (GUIs)

A. Nagaraj [1], P. L. Mills [1],
[1] Department of Chemical and Natural Gas Engineering, Texas A&M University - Kingsville, Kingsville, TX, USA

Chemicals are an integrated part of our daily life. While chemicals are significant contributor to a nation’s economy, sound management of chemical production is essential for environmentally friendly operation without maximizing operational costs. Next generation technologies must be ... Mehr lesen

Computer Simulation of Microwave Heating of Initially Frozen Sandwiches Using COMSOL Multiphysics® Application Builder

D. Fu [1], L. Wang [2], J. Liao [1], S. Dus [1], K. Bearson [1],
[1] Tyson Foods, Downers Grove, IL, USA
[2] Simulprocess, Summerfield, NC, USA

Customers typically prepare sandwiches using a microwave oven to heat a frozen sandwich. This causes huge temperature variations and quality issues due to multicomponent with different dielectric and physical properties and with phase changes at different freezing points in the heating ...

FEM Convergence for PDEs with Point Sources in 2-D and 3-D

M. Gobbert [1], K. M. Kalayeh [2], J. S. Graf [1],
[1] Department of Mathematics and Statistics, University of Maryland - Baltimore County, Baltimore, MD, USA
[2] Department of Mechanical Engineering, University of Maryland - Baltimore County, Baltimore, MD, USA

Numerical theory provides the basis for quantification of the accuracy and reliability of a FEM solution by error estimates on the FEM error vs. the mesh spacing of the FEM mesh. This paper presents techniques needed in COMSOL Multiphysics® software to perform computational studies for ... Mehr lesen

Design of Solar Thermal Dryers for 24-hour Food Drying Processes

F. S. Alleyne [1], R. R. Milczarek [1],
[1] Healthy Processed Foods Research Unit, U.S. Department of Agriculture, Albany, CA, USA

Solar drying is a ubiquitous method that has been adopted for many years as a food preservation method. Most of the published articles in the literature provide insight on the performance of solar dryers in service but little information on the dryer construction material selection ... Mehr lesen

Preliminary Study of Particle Trajectory and Secondary Flow in Bend Configurations to Reduce Erosion

O. Ayala [1], A. Arruda [2], L. Calembo [2], E. Enes [2], D. Monteiro [2], R. Paizante [2], A. Rocha [2], M. Simões [2], J. Michaeli [1],
[1] Department of Engineering Technology, Old Dominion University, Norfolk, VA, USA
[2] Brazil Scientific Mobility Program, CAPES, Brasilia, DF, Brazil

To the best of our knowledge, only few researchers have made attempts to minimize the erosion in bends by modifying the bend configuration in order to alter the particle-laden flow pattern to reduce the erosion. In this work, we revisited those previously proposed bend configurations to ... Mehr lesen
