Numerical Modeling of the Temperature Distribution Within a Bonded Paper Web When Undergoing Microwave Heating in a Waveguide

In this paper, a numerical technique is used to study the temperature distribution within the heated bonded paper web placed in a waveguide. The parameters of the problem were selected so as to best locate the test sample that would generate the desired absorbed power. The method of false transient was utilized to accelerate the numerical convergence and the equations were discretized with central difference in both time and space. The resulting system of equations was solved using an Alternating Direction Implicit scheme. Good agreement was achieved between the numerical solutions and the experimental validations.
