Rapid sand casting of cylinder head

ProCAST software is used as sand mold casting simulation software to solve the interface heat transfer coefficient, but there are still some deviations in the setting of many physical parameters, which also has a certain impact on the simulation results. For example, the permeability of sand box and the...
