Abstract:Based on validating results by heat balance test for aluminum melting furnace, a reasonable mathematical model which considering the feature of the aluminum melting process was established. The numerical simulation of coupling field between combustion space and aluminum bath in a round aluminum melting furnace was carried out using CFD software FLUENT. The influence of the swirl number on melting process of the aluminum melting furnace was analyzed. According to optimizing criterion which is put forward in this work, the optimal melting performance is obtained when the swirl number is larger than 0.6.
Key words: aluminum melting furnace; swirl number; melting process; numerical simulation
