中文摘要：

采用Fluent计算流体力学软件,通过修正动量方程考虑摇摆所造成的附加惯性力的影响,对摇摆竖直矩形窄流道内单相流动与换热过程进行了数值模拟。附加惯性力的影响通过用户自定义函数（UDF）在动量方程源项中实现。模拟结果显示,在摇摆作用稳定后,流量和温度都会在静止值附近正弦波动,且波动周期和摇摆周期一致;流量和温度波动的极值都出现在系统从最大摇摆角度向平衡位置运动的过程中;摇摆、流量和温度波动三者之间存在相位差;摇摆周期减小和最大摇摆角度增加都会使波动幅度增加。模拟得到的结论与已发表文献结论相吻合。若将系统关于摇摆轴心对称布置,则可降低摇摆造成的参数波动。

英文摘要：

Based on the Fluent,numerical simulation of single-phase flow and heat transfer in vertical and rectangular channel under the rolling effect of motion had been studied firstly with the modification of momentum equation,which is induced by the additional inertia forces.The additional inertia forces were added to the source term of momentum equation through User Defined Function（UDF）.The results show that,the flow rate and temperature flucuate around the stationary value with sinusoid,and the fluctuation period coincides with the rolling period.The extremum of flow rate and temperature appears between the maximum rolling angle and equilibrium position.Phase difference exists among the rolling,flow rate and temperature.The decrease of rolling period and increase of maximum rolling angle enlarge the amplitude of fluctuation,and the fluctuation can be reduced when the system distribution is symmetric around the rolling axis.The simulation conclusions agree well with the experimental results in the released literatures.
