| 摘 要： | 格子-Boltzmann数值模拟方法(LBM),在最近十几年来得到迅速发展。本文发展了LBM的流动与传热模型,并对二维平板通道中的流动与传热进行了模拟,采用密度分布函数得到速度场,用单独的内能分布函数得到温度场,并与传统FVM方法所得到的多个特征量结果进行了比较,模拟结果与FVM解均吻合很好。鉴于LBM边界条件处理简单和易于实施等特点,该方法可望成为求解流动与传热的一种有效数值模拟手段。

| Abstract: | The recent development of the lattice Boltzmann method (LBM) has provided a new simulation tool for computational fluid dynamics and numerical heat transfer. Forced convective flow and heat transfer between two parallel plates are studied using LBM in this paper. The velocity field is simulated using density distribution function while an internal energy distribution function is introduced to simulate the temperature field. The results agree well with data using traditional finite volume method (FVM) and analytical solution. The present work indicates that LBM may be developed as a promising method for predicting fluid flow and heat transfer because of its many inherent advantages. |
