Internal Heat Generation Estimation During a Microwave Heating Process


Background/Objectives: This article describes a way for estimating the internal heat generation function during microwave heating processes. Methods: We solve the corresponding inverse problem to estimate the internal heat generation function. We consider an illustrative example dealing with the heating of solid spherical Silicon Carbide samples. We used two numerical strategies: The Spiral Optimization Algorithm and the traditional Levenberg-Marquardt method. Findings: Even if both approaches differ in nature, our results indicated an excellent agreement between both numerical strategies. Applications: With this method, it is possible to estimate with high precision this important parameter in microwave heating processes.
