  1. In the thesis the low drag - low noise optimization of the vehicle main form design is realized, main accomplishments are as follows. researched the knowledge of drag and flow noise, the parameters of the boundary layer are calculated by the hess - smith method and boundary layer momentum integral method. the calculation of the length of transition zone and change in boundary layer displacement thickness between laminar and turbulent states in the transition is improved, then the drag coefficient and self - noise from the transition zone are calculated as the objective functions of the optimization

    主要研究內容和成果如下:對航行繞流流場進行分析,深入研究了阻力和流噪聲產生機,建立了阻力系數和自噪聲的評計算模型;採用面分佈源匯法和邊界層動量積分法對繞流流場的流體動力參數進行計算,改進了轉捩區長度和邊界層位移厚度的計算,應用於航行頭部駐點自噪聲的計算;最後設計了阻力系數和自噪聲數計算程序模塊。
