abstract = "The most popular jet noise prediction method is based on Reynolds Averaged Navier-Stokers (RANS) calculation in engineering, which is mostly devoted to industrial application in a reasonable CUP time. MGBK model and Tam's model (usually called TA model) are two most popular jet mixing
noise prediction methods. However, the two prediction methods describe the sound source and propagation from entirely different aspects. Morris suggests that, assuming that consistent assumptions are made, the two different models would yield identical noise prediction result. Considering
the contribution of noise is only due to the self-noise in vertical to jet axis direction in MGBK method, and Tam's model is supposed to predict the small-scale turbulence noise, which is dominant in the same direction, this paper compares the prediction results with the two methods in the
vertical to the jet axis direction. Comparison and analysis are made, involving differences of the results with various parameters in two models. The advantages and disadvantages of each prediction model are also included in the paper. Moreover, the suggestion would be made to approve the
prediction method of jet mixing noise, through the analysis of the different results and their causes.",
