Effects of Sample Shapes and Thickness on Distribution of Temperature inside the Mineral Ilmenite Due to Microwave Heating
The study of interaction between microwave radiation and minerals is gaining increasing interest in the field of minerals and material processing. Further studies are, however, still required to
A nonlocal formulation for the problem of microwave heating of material with temperature dependent conductivity
Abstract. Microwave electromagnetic heating are widely used in many industrial processes. The mathematics involved is based on the Maxwell’s equations coupled with the heat equation. The thermal
Radio frequency (RF) treatment of dielectric materials emerges as an alternative and efficient way of heat treatment recently. But application of the system on various fields necessitates a good
Effects of temperature, moisture, and metal salt content on dielectric properties of rice bran associated with radio frequency heating
Results indicated that both ε′ and ε″ of RB samples increased with increasing temperature and MC, and the increase rate was greater at higher temperature and moisture levels than at lower levels, especially at frequencies lower than 300 MHz.
Numerical and experimental analysis of heat transfer in inductive conduction based wire metal deposition process
An inductive conduction heating process to heat the extruder in wire additive manufacturing is explored through numerical simulation and an in situ infrared imaging. The 2 D Finite Element Method
Finite element (GFEM) simulations on the effect of microwave heating for lossy dielectric samples with various shapes (circle, square and triangle)
This paper aims to investigate the thermal performance involving larger heating rate, targeted heating, heating with least non-uniformity of the spatial distribution of temperature and larger


Experimental and Numerical Analysis of Microwave Heating of Water and Oil Using a Rectangular Wave Guide: Influence of Sample Sizes, Positions, and Microwave Power
The heating process of water and oil using microwave oven with rectangular wave guide is investigated numerically and experimentally. The numerical model is validated with an experimental study. The
An Analysis of Temperature Distributions in Microwave Heating of Foods with Non-Uniform Dielectric Properties
Using flat cylindrical samples having non-uniform dielectric properties, we studied the heat transfer in food products when only the side surfaces of the samples were irradiated with microwaves. The
Analysis of microwave heating of materials with temperature-dependent properties
In this paper transient temperature profiles in multilayer slabs are predicted, by simultaneously solving Maxwell's equations with the heat conduction equation, using Galerkin-finite elements. It is
Radio Frequency Heating of Foods: Principles, Applications and Related Properties—A Review
It is evident that frequency level, temperature and properties of food, such as viscosity, water content and chemical composition affect the dielectric properties and thus the RF heating of foods, and these parameters should be taken into account when designing a radio frequency heating system for foods.
