Modeling of Susceptor Assisted Microwave Heating in Domestic Ovens
نویسندگان
چکیده
Susceptors are used in microwavable food packages to facilitate preferential heating. Modeling of susceptor assisted microwave heating in domestic ovens was performed using radio frequency and heat transfer modules of COMSOL Multiphysics 4.2. Two different approaches (domain discretization and transient boundary condition) were studied for taking into the account of discretizing thin susceptor film in the computational domain. Simulated temperature profiles were compared with microwave heating of 1% gellan gel cylinder placed with a susceptor film on top. There was good agreement between the experimental and simulated spatial temperature profiles. Error value of a point transient temperature profile was 1.51°C. The transient boundary condition approach was found to be better considering the computational time of 1 h compared to 5 h in domain discretization method. We also studied a method to model shielding effect of microwavable package and discussed its heating pattern.

Heating Performance Assessment of Domestic Microwave Ovens
Due to inherent nature of standing wave patterns of microwaves inside a cavity and dielectric properties of different components in a food, microwave heating leaves non-uniform distribution of energy inside the food volumetrically. Achieving heating uniformity plays critical role in improving the safety of microwave heated products. In this paper, we present a method for assessing heating unifo...
