Modelling the dynamics of temperature field morphology of a heat pipe with a case defect

As part of a computer experiment with the use of the finite element method, a method was developed for analyzing the morphology of the non-stationary temperature field of a heat pipe which has a localized structure defect in its case. It is shown that within the model of a steady start of HP (τ = 0 ÷ 120 s.) and maximum temperatures of PHFS T_PHFS = 350 ÷ 400 K, the presence of a defect causes the variability of the shape of isotherms over time and the nature of the temperature distribution along the HP axis. In this case, the distance from the center of the HP to the front of the isothermal line uniquely determines changes in the morphology of the temperature field.
