摘　　要：以玉米的常规存储形式为研究对象,利用计算流体动力学软件Fluent,建立玉米烘干过程的有限元分析模型,通过该分析找到温度变化规律,为设计高效的烘干设备提供指导依据。分析结果表明:1)、在热风风速为0.8m/s、热风温度为343K时,玉米籽粒表面温度分布最均匀,并且玉米籽粒最高温度不会超过333K。2)、玉米表面温度分布均匀性会随着入风口数量的增加而增加,玉米与风速的角度改变不会对玉米表面温度分布均匀性造成影响。Taking the conventional storage form of corn as an object, using calculating hydrodynamic software Fluent, this paper establishes a finite element analysis model of corn drying process. Through the analysis, it finds out the temperature change rule, which provides guiding basis for the design of efficient drying equipment. The analysis results show that the temperature distribution of corn kernels is even and the highest temperature is below 333K when the speed of hot winds is 0. 8m/s and the temperature is 343K;The distribution uniformity of corn surface temperature increases with the quality of fluid inlet and the change of the angle between corn and velocity will not impact the temperature distribution of corn.
