Finite Element Modeling of Heat Transfer Modes in Local Gap Formation During Solidification of Cast Components CILAMCE-2023

Resumo

In the casting process, there is the casting and the mold. Due to the temperature difference between
these two parts and the fact that materials present physical deformations due to this temperature variation, there is
the phenomenon of the appearance of gaps between the components. This work then aims to analyze the influence
of how the development of these gaps occurs during solidification, on the resulting local cooling curves of the
casting. Using a finite element software, different simulations were performed that show different approaches to
the evolution of the process, considering different plots and behaviors of the heat transfer phenomena - conduction,
radiation, convection. Through the study and correct definition of the model parameters, the outputs generated by
the program were observed and evaluated in graphic and tabular form, confirming the possibility of analyzing the
piece locally, with satisfactory results regarding the general aspect of the heat exchange phenomena and gap
formation involved in the process.
