Mathematical description of microwave drying requires the solution of two different physics: electromagnetics in the microwave oven cavity and food material and, transport process (mass, momentum and heat transport) in the food material. Maxwell’s equations for electromagnetics were ... Read More
The purpose of this study is to predict, with a multiphysics model, the degradation area of a composite material when a current is injected into the material. The main physical phenomenon is an exothermic reaction, with an irreversible nonlinear variation of the electrical conductivity. ... Read More
This work is dedicated to exact numerical modeling of modal dispersion and thermal noise in arbitrary cylindrical symmetric WGM structure. We develop a method and compare the results with experimental data from literature. We show that the real form of the resonator makes small influence ... Read More
