Project Description and Objectives:
Single-crystal blades with perfect high-temperature mechanical properties are one of the most important parts in gas turbines. Due to the complex geometry of the blade, defects are prone to be formed in the castings. In order to avoid these defects, we should develop a deeper understanding of the directional solidification of the single-crystal blade. In this project, we will utilize the numerical model to simulate the directional solidification of a single crystal blade in the Bridgman furnace. The characteristics of the heat transfer and solidification sequence will be discussed based on the simulation results. Optimization of the process design (including but not limited to furnace and shell mold) and the selection of operating parameters will be proposed according to the analysis, and then estimated using further simulations. The obtained results will extend the understanding of the radiative heat transfer patterns in the furnace, and improve the furnace design and the parameter control in the fabrication of single-crystal blades.
