...Waraporn Klinbun; Phadungsak Rattanadecho The present work studies numerically the heating of multilayer porous packed bed which is subjected to the microwave radiation with a rectangular waveguide. The multilayer porous packed bed consists of the layers of fine and coarse beds. The simulations...

...Phadungsak Rattanadecho; Waraporn Klinbun This paper proposes mathematical models of the microwave heating process of dielectric materials filled in a rectangular waveguide with a resonator. A microwave system supplies a monochromatic wave in a fundamental mode ( TE 10 mode). A convection exchange...

...P. Rattanadecho; N. Suwannapum; W. Cha-um Microwave heating-drying of hardened Type I-cement paste using a rectangular waveguide is a relatively new area of cement-based materials research. In order to gain insight into the phenomena that occur within the waveguide together with the temperature...
