摘要:

鑄造過程數值建模已經成為預測鑄造缺陷、優化鑄造工藝的一種關鍵有效工具。界面換熱系數是鑄造數值建模的重要邊界條件之一，難以通過直接測量獲取，常通過反算技術確定。反算技術具有非線性、計算量大和解不適定等特性，增加了反算求解的難度。綜述了鑄造數值建模過程中界面換熱系數反算技術的研究現狀和最新進展，歸納了界面換熱系數的主要反算求解方法，并詳細論述了基于反算法的界面換熱系數對于鑄造過程數值建模精度的影響。探討了現有反算技術的不足和局限性，并提出了界面換熱系數反算技術的未來研究方向和發展趨勢。

Abstract:

Numerical modeling in the casting process has become a key tool for predicting defects and optimizing processes. The interfacial heat transfer coefficient is one of the important boundary conditions in casting numerical modeling, which is difficult to be obtained by direct measurement and is often determined through inverse calulation technique. The inverse calulation technique have characteristics such as nonlinearity, large computational requirements and non-unique solutions, which increase the difficulty of inverse solution. This work reviews the current research status and latest developments of the interfacial heat transfer coefficient inverse calulation technique in casting numerical modeling, summarizes the main inverse solution methods of the interfacial heat transfer coefficient, and elaborates on the impact of the inverse algorithm-based interfacial heat transfer coefficient in numerical modeling of the casting process. The limitations and shortcomings of the existing inverse calulation technique are discussed, and future research directions and technological development trends are proposed.
