The extent of the influence of a radiation baffle on the temperature field and gradient in the ceramic shell mould and CMSX-4 single crystal casting manufactured using the Bridgman method was determined. The numerical simulation was conducted to predict the temperature distribution in the casting with and without the use of a radiation baffle. The geometric model assembly, as well as a three-dimensional study of the area surrounding the ceramic shell mould (also called “ambient), was developed, and the proper boundary conditions were selected. The authors verified experimentally the boundary conditions and predicted temperature distribution in the casting for the developed model and the three-dimensional area surrounding the ceramic shell mould. The value of temperature gradient in the mushy zone of the casting was calculated on the basis of the predicted casting temperature.
