Extract

Computer modeling and simulation of microwave processing systems provide significant advantages that are expected to play an important role in the development, scale-up, commercialization, and effective utilization of microwave heating technology. These advantages include the following:

• Understanding of the physical aspects of microwave interaction with materials. Microwave heating is a complex process, and computer modeling may help identify the role of materials properties, dimensions, input power, heating rates, etc. on the effective use of microwave heating procedures. Hybrid microwave heating often refers to the use of SiC rods, or lining the insulation surrounding the sample with thin SiC coatings, to help stimulate the microwave heating process. This is particularly important when microwaves are used to sinter low-loss materials that do not effectively absorb electromagnetic radiation. This complex hybrid heating process may lead to unpredictable results in routine microwave heating experiments; and many aspects of its procedure may be simulated, evaluated, and possibly optimized using computer modeling. For example, the number, dimensions, and locations of SiC rods in a typical picketfence arrangement and the thickness of SiC sheets that may be used to allow effective stimulation of the heating process, while still not shielding the sample from the microwave energy, may be better understood, and guidelines for experimentations may be developed using numerical simulation.
