Improving Heating Uniformity of Dried Fruit in RF Treatments for Pest Control: Model Development and Validation

B. Alfaifi[1], J. Tang[2], Y. Jiao[2], S. Wang[3], B. Rasco[2], S. Jiao[2], S. Sablani[2]
[1]King Saud University, Riyadh, Saudi Arabia
[2]Washington State University, Pullman, WA, USA
[3]Northwest A&F University, Yangling, Shaanxi, China

Non-uniform heating is one of the most important challenges during the development of radio frequency (RF) heat treatments for pest control. A computer simulation model using finite element–based COMSOL Multiphysics® software was developed to investigate the heating uniformity of raisins ... En savoir plus

CFD/Electromagnetics Interactions via Realistic Heat and Mass Transfer to Moist Substrates

G. Ruocco[1], M. V. De Bonis[2]
[1]Engineering College, University of Basilicata, Potenza, Italy
[2]Institute of Food Science and Production, National Research Council, Bari, Italy

Localized convection heat and mass transfer can be intensified and optimized by providing exposure to electromagnetic energy. Conjugate heat and mass transfer are configured by solving the momentum, heat and mass transfer simultaneously in both solid (substrate, comprising of a two-phase ... En savoir plus

Pulsed Power Accelerator Design with COMSOL Multiphysics® Software

D. Reisman[1]
[1]Sandia National Laboratories, Albuquerque, NM, USA

We have developed Thor: a pulsed power accelerator for performing dynamic material experiments. The design was aided by using the COMSOL Multiphysics® software with the AC/DC Module and RF Module. Our design process involved optimizing the impedance of the system while maintaining a good ... En savoir plus

Reliable Full-Wave EM Simulation of a Single-Layer SIW Interconnect with Transitions to Microstrip Lines

J. L. Chavez-Hurtado[1], J. E. Rayas-Sanchez[1], Z. Brito-Brito[1]
[1]ITESO - Universidad Jesuita de Guadalajara, Tlaquepaque, Jalisco, Mexico

We present a procedure to obtain reliable EM responses for a SIW interconnect with microstrip line transitions. The procedure focuses on two COMSOL® configuration settings: meshing size and simulation bounding box. Once both are properly configured, the implemented structure is tested by ... En savoir plus

Optimization of Active Packaging for Microwaveable Food Products Using COMSOL Multiphysics®

S. Landa[1], A. Bardenstein[1]
[1]Danish Technological Institute, Taastrup, Denmark

Upon operation, the magnetron of a conventional microwave oven induces a pattern of standing electromagnetic waves in the oven cavity. Interactions with the field define the amount of energy absorbed in a part of a food object within the cavity. The well-known inhomogeneous heating ... En savoir plus
