摘    要:基于喷流混合噪声半经验预测方法 TA理论模型,设计了喷流混合噪声半经验预测模型程序。其中流场计算通过商用软件ANSYS,如ICEM和FLUENT实现,声场计算通过Fortran90代码编译完成,仿真计算得到的喷流噪声远场声压级与Tam等人的实验数据吻合较好。同时提出了一种简化计算方法,在保证计算结果准确性的前提下,明显提高了计算速度。

关 键 词:喷流噪声  半经验  TA模型

Abstract:This paper discusses the design process of computational codes of jet noise semi-empirical prediction method based on TA model. In this work, the flow field is simulated by ANSYS Software, such as ICEM and FLUENT. The sound pressure level is calculated by Fortran90 codes. The results of the computation codes agree well with the experiment data of Tam. We also refer to a simplification method to cut down the CPU time and satisfy the accuracy as well.
Keywords:jet noise  semi-empirical  TA model
