摘要 在对各种交错网格离散格式的奇偶不耦合数值误差进行了详细的傅里叶分析和比较后 ,采用一种紧致的交错网格有限体积法将纳维 -斯托克斯方程和k ε湍流模型方程紧密的耦合在一起求解 ,发展了一套三维定常流程序 .通过对NASARotor 67设计和非设计工况内部流场的数值模拟结果与实验的比较、分析 ,初步验证了程序的准确性和可靠性 . A compact staggered mesh limited control volume scheme was used in a three-dimensional steady computational fluid dynamics code to solve the Navier-Stokes equations and k-Ε turbulence model equations more tightly, after Fourier analysis for odd-even decoupled mode in several staggered mesh discretization. NASA Rotor 67 flow field was calculated and flow structures in terms of relative Mach numbers were presented. The excellent agreement between simulations and experiments not only under design condition, but also nondesign condition demonstrates the code's predictive capability. The cause of the discrepancies was discussed. The code has the advantage of calculation efficiency as compared with some other software.
