Abstract: To predict three-dimensional temperature distribution of molten aluminum and its influencing factors inside an industrial aluminum holding furnace, a fluid-solid coupled method was presented. The fluid-solid coupled mathematics models of aluminum holding furnace in the premixed combustion processing were established based on mass conservation, moment conservation, momentum conservation, energy conservation and chemistry species conservation. Computational results agree well with the test data of the typical condition. The maximum combustion temperature is 1 850 K. The average temperature of the molten aluminum is 1 158 K, and the maximum temperature difference is about 240 K. The average temperature increases 0.3 ℃ while the temperature of combustion air increases 1 ℃. The optimal excess air ratio is 1.25-1.30.
