“…The simulations showed a slight deviation (maximum 0.17 %), which may be due to the inaccuracy of measurement by temperature sensors, also the mathematical-physical model based on which the simulations were performed did not have to enter exact material characteristics and physical quantities corresponding to the state as in the experiment. For example, according to (Krajčík et al 2021), the problem in connection with the airflow in the hotbox of the climate chamber (see Fig. 3) was solved, which has a significant effect on the heat transfer coefficient on the interior side.…”

“…During the validation of the numerical model, the total heat transfer coefficient on the inner surface was adjusted based on the results of experimental measurements. In subsequent heat transfer calculations by Krajčík et al (2021), the total heat transfer coefficient on the inner side surface was 8 W/(m 2 . K) for radiant wall heating and 7 W/(m 2 .…”

“…Em geral, é notado que a velocidade de estabilização das temperaturas das faces internas reduziu quando a temperatura da serpentina de cobre aumentou. Este resultado concorda com pesquisas experimentais sobre resposta térmica de superfícies internas verticais com tubos de calor (Krajčík et al, 2021;Li, 2020). As Figuras 16 e 17 mostram a distribuição da temperatura da SF, assim como as taxas de resfriamento da superfície, para CT, empregando-se a Equação 1.…”
