The research on Numerical Simulation of China’s foundry industry began in the late 1970s. However, it has developed rapidly together, and has been closely combined with production practice, forming the characteristics of China in this research field. Since 1978, China has organized outstanding scientific researchers from major universities and research institutions to carry out a number of scientific and technological research projects, and developed a series of computer simulation software through unremitting efforts. Wang Junqing of Shenyang Foundry Research Institute used simple, SMAC and sola. VOF to simulate the filling process during her doctoral degree at the University of science and technology of Denmark.
The research on computer simulation of mold filling process in China started late. The numerical simulation of mold filling process needs to determine the free surface condition of flow field and temperature field at any time. The flow field and temperature field are changing and affect each other, so its computer simulation is a very complex numerical simulation problem.
In the 1980s, China began to study the numerical simulation of casting filling process. In the early 1980s, Taiwan scholar Huang Wenxing first applied hydrodynamics to casting filling simulation, which opened up a new field of filling process research.
In 1994, Shenyang Foundry Research Institute combined simple algorithm with SMAC method to simulate the flow field in the mold filling process of sleeve and plate die castings, and carried out the comparison and verification of hydraulic simulation.
In 1995, Chen Liliang of Huazhong University of technology put forward a set of three-dimensional mathematical model of gasification mold filling, and developed the corresponding numerical simulation software of filling process. At present, the software with independent intellectual property rights developed in China includes Huazhu CAE of Huazhong University of science and technology, R-star of Tsinghua University and CASTsoft of Zhongbei University. These software can meet the requirements of temperature field, flow field analysis and coupling calculation of flow and heat transfer during mold filling and solidification of various common materials under different casting methods.
