摘要
在TRIP软件定常模块的基础上,采用双时间法和动网格技术开发了非定常模块。通过NA-CA0012翼型小攻角俯仰振荡和深失速两个算例的计算,对比分析了不同网格规模、湍流模型、时间步长等的模拟结果,并与试验数据做了比较,结果表明计算结果与试验数据基本一致,验证了TRIP2.0软件的非定常模块的正确性和精度。
Based on the steady flow module of the TRIP software, the unsteady flow module is developed, using a dual time algorithm and a dynamic grid technique. According to the calculation of NACA0012 airfoil small angle pitching motion and deep stall, and the analysis of the computation results of different mesh size, module and time etc. , the experiment results shown that the computation results are basically accordant to the experiment date and shown the correctness and precision of TRIP 2.0 software unsteady module.
