Abstract
This paper is a continuation of a previous research in which was presented a method to determine heat transfer coefficient values corresponding to crimped connections. Because the differences between numerical values of temperature obtained with a mathematical model for hΣ and experiments were high, authors considered that the model could be improved. Therefore, in the presented paper are shown the results obtained for heat transfer coefficient and temperature corresponding to crimped connections using an improved model. It was started from some values determinated previously and there were obtained new values of hΣ which can give the possibility to attain the temperature values closed to experiments. The numerical model was developed considered a coupled problem – Magnetic- Steady State Heat Transfer. Using iteration there were determined new values for heat transfer coefficient which gave the possibility to find the Joule heat, heat flux and temperature distribution in the studied crimped connection. Thus, the numerical model can be used to determine the temperature values for several types of crimped connections with small errors.
