Structure design of aluminum alloy solution furnace based on fluid-solid coupling numerical simulation

摘要

Solution furnace is one of the main equipment in the heat treatment process of aluminum alloy. The distribution of flow field and temperature field in solution furnace directly affect the heat treatment quality of alloy parts. In order to comprehensively consider the influence of flow channel structure, fan system and thermal insulation layer on the flow field and temperature field in the furnace during the design process of the solid solution furnace, the method of computational fluid dynamics is applied to carry out the fluid-solid coupling numerical simulation in the CFD software for the virtual design of the equipment. The accuracy of the model was verified by experiments, and the temperature uniformity in the solution furnace reached ± 5k
