中文摘要：

针对沥青加温罐内的沥青介质受热不均匀和加速率较低的问题，以某大型沥青加工站的沥青加温罐为研究对象，对罐体内的沥青流体建立三维模型，使用FLUENT软件、RNG κ-ε湍流模型和多重参考系（MRF）法求解。对比分析了在不同搅拌装置布局下，加温罐内沥青流体的湍流强度与速度，得到了最优的搅拌装置布局方案，使沥青的成品质量有了明显提高。

Aimed at the problems of uneven heating and low rate heating in asphalt heating tank, the asphalt heating tank in a major asphalt processing station was taken as the study object, and a 3D model of asphalt fluid in the heating tank was established. RNG κ-ε turbulence model and Multiple Reference Frame optimum scheme for stirring speed signif method were device layout asphalt fluid in various layouts, icantly improved applied to the FLUENT software for solution. The was obtained by comparing the turbulence strength and and the production quality of asphalt was proved to he
