Estimation of thermal properties of a solid sample during a microwave heating process

Çok Merkezli Girdap Arama Algoritması

“…(García, Amaya, & Correa, 2018) [23] bir mikrodalga ısıtma işlemi sırasında termal difüzyon ve iletkenliği tahmin etmek amacıyla Tepe Sinyal-Gürültü Oranını amaç fonksiyonu olarak kullandılar ve Spiral Optimizasyon Algoritması (SOA), GAA algoritması ve Ağırlık Cazibe Yöntemi (WAM) algoritmalarını bu problemin çözümünde kullandılar. Üç algoritma da beklenen çözüme yakınsama sağlamış olmak birlikte GAA algoritmasının çok daha hızlı bir şekilde sonuca ulaştığını belirttiler.…”

Thermal diffusivity from Fourier’s inverse problem supervised by an optimization model: Theoretical analysis and experimental validation

“…In recent studies, the problem of predicting thermal diffusion parameters was performed for diverse applications and by using different techniques. For example, in [25] simulated thermal images were used to predict thermal diffusion parameters during microwave heating procedure, in [26] coupling controlled environmental forcing and a transient plane source method were employed for building insulation material applications, and the Ångstrom method was used in [27] to measure the heat diffusivity for the vapor chambers and in [28] to numerically obtain the temperature distribution for the polymers.…”

“…Besides the above mentioned experimental techniques, there are also many mathematical strategies that have been implemented for modeling the response of measurement devices. Several mathematical schemes are based on inverse problem procedure [8,25,[29][30][31][32][33] and consist of two fundamental steps. Firstly, the specific solution that arises from a priori and suitable initial and boundary conditions is analytically or numerically determined.…”
