| 摘 要： | 基于粘性非结构混合网格,采用格心格式的有限体积法,应用Spalart-Allmaras湍流模型进行绕三维舵面流动的N-S方程数值模拟。操纵面铰链力矩的计算结果与风洞试验结果的对比分析表明,计算方法对粘性流动具有良好的适应性。对舵面铰链力矩随迎角、马赫数、雷诺数变化的规律也进行了分析研究。

| Abstract: | Based on viscous unstructured hybrid grids and using the cell centered finite volume code,the flow around a three-dimensional control surface is simulated by solving the N-S equations and using the Spalart-Allmaras turbulence model.The results of hinge moment of control surfaces by calculating and by wind tunnel tests are compared and analyzed.The results show good adaptability of theory and method applied in this paper for simulating the viscous flow.Moreover,the rule of hinge moment of control surfaces varying with angle of attack,Mach number and Reynolds number is researched. |
