摘要

为了更精确地求解滑移流区稀薄气体外掠圆柱体流动与传热问题

基于有限容积法的ANSYS FLUENT平台提出了一种滑移边界修正的数值模型

该模型考虑了完整的一阶速度滑移和温度跳跃

其中一阶速度滑移包括了轴向温度引起的热蠕动影响和壁面曲率影响。将模型计算值与实验数据进行了充分对比

结果表明:当气体流动处于连续流区时

滑移边界修正模型与无滑移边界直接模拟计算误差很小; 当气体流态处于滑移流区时

采用滑移边界修正模型可实现对该流态气体流动与传热的精确预示(相对误差在±2.5%); 稀薄效应对低压气体外掠圆柱体的流动特性影响显著

随着克努森数增加

最大无量纲滑移速度呈线性增加

而最大表面摩擦系数呈线性降低。本文方法可广泛应用于工程之中

以探索低压气体的换热机理

为研究稀薄气体滑移流区流动与传热问题提供了一种有效的数值计算方法。

Abstract

To more accurately solve the problem of rarefied gas flow and heat transfer over a cylinder in slip flow regime

based on the ANSYS FLUENT platform of finite volume method

a modified numerical model of slip boundary is proposed. The first-order velocity slip and temperature jump are considered in this model

and the first-order velocity slip includes the effects of the thermal creep caused by axial temperature and the curvature of wall surface. Compared with experimental data

the errors of the values calculated by modified model of slip boundary and by direct simulation without slip boundary are very small when the rarefied gas flow is in the continuous flow regime. The precise prediction of flow and heat transfer characteristics can be achieved by using the present model

and the relative error is ±2.5% when the rarefied gas flow is in the slip flow regime. Rarefying effect has significant influence on the flow characteristics of low pressure gas over a cylinder. With the increase of Knudsen number

the maximum dimensionless slip velocity increases linearly

while the maximum surface friction coefficient decreases linearly. This method can be widely used in engineering to explore the heat transfer mechanism of low pressure gases

and may become an effective numerical method for the study on the flow and heat transfer of rarefied gases in slip flow regime.
