Comparative Simulation of the Dynamic Regimes of Resistive Heating Elements

The problem of modeling and simulation of the dynamic regimes of the electro-thermal plants in general, proves to be extremely complex. Such a simulation must take into consideration many parameters which can change depending on the plant temperature. Such evolutions (with different degrees of nonlinearity), can appear close to the heat sources, but also in areas that are using the heat. This paper aims to simulate the behavior differences between a spiral heating element in open air and a metallic resistive heating element, by simulating them simultaneously on already tested Matlab-Simulink models. These observations will finally allow some conclusions to be drawn, regarding the dynamic behavior of these heating elements. It will also allow assessments of the suitability of one or the other, depending on the specifics of the complex equipment to which it will belong.
