Analysis of Power Density Distribution in Microwave Ovens

Modeling the heating uniformity contributed by a rotating turntable in microwave ovens

“…The earliest efforts in this area were primarily analytical (Shou-Zheng & Han-Kui, 1988;Watanabe & Ohkawa, 1978). However, with the availability of extensive computing facilities, solution of Maxwell's equations for electromagnetics coupled with heat transfer in the oven cavity can be obtained using different numerical methods such as finite difference time domain (FDTD) method (Dincov, Parrott, & Pericleous, 2004;Ma et al, 1995) and finite element method (FEM) (Zhang & Datta, 2000).…”

“…Microwave ovens heat food volumetrically by electromagnetic radiation. The process of microwave heating of foods has been extensively studied, both experimentally (Nott & Hall, 2005;Swain, Russell, Clarke, & Swain, 2004) and theoretically using analytical (Shou-Zheng & HanKui, 1988;Watanabe & Ohkawa, 1978) and numerical methods (Knoerzer, Regier, & Schubert, 2006;Ma et al, 1995). Numerous methods have been suggested to improve heating uniformity in microwave ovens that include using microwaves in combination with some other heating source, changing food composition and using active packages like shields and susceptors.…”

Simulation model for moving food packages in microwave heating processes using conformal FDTD method

“…The literature contains numerous reports on analytical models to describe electromagnetic fields inside domestic microwave ovens (Paoloni, 1989;Watanabe and Ohkawa, 1978;Webb et al, 1983;Shou-Zheng and Han-Kui, 1988). But only electromagnetic field distributions were considered in these studies.…”

Coupled electromagnetic and heat transfer model for microwave heating in domestic ovens

“…A computer simulation of microwave heating of foods could facilitate proper designing of foods to assure microbial safety. Extensive modeling efforts have been made to simulate microwave heating using simple analytical approaches (Watanabe et al, 1978) to computational approaches solved using numerical methods. Researchers have made assumptions to simplify the problem and reduce the computational time.…”
