Abstract

This research presents a 3-D mathematical model to simulate the behavior of the sample with different air hole structure under microwave heating. Results show that the air holes interfered with the coupling of the composite material and Multiphysics; the air holes (d/Λ) between the ranges 0.56 to 0.72 had a positive effect coupled with the electromagnetic field where material absorbing efficiency has a significant improvement. Different air hole size arrays showed diverse heating effects, and the heating efficiency was improved and formed energy concentered to the core when the diameters of outmost cladding air holes were different from others. In particular, irregular air hole arrays interfered the distribution of standing waves in the microwave oven, and the change of the standing wave also led to the hot and cold spots transfer. This study will guide to explore the energy aggregation and transmission in microwave heating models.
