摘要
基于Fluent等软件平台和standard k-e湍流模型,介绍了地面雷达数值风洞技术的实现方法,同时对模型建立、网格划分等关键技术进行了详细介绍,通过实例进行了计算并将计算结果与试验结果进行了对比分析和验证,结果表明,采用数值风洞的理论和方法,实现地面雷达风洞试验的数值化是可行的,误差是可以接受的,最后对雷达系统数值风洞技术的未来发展作了展望。
In this paper, it was introduced the method to apply numerical wind tunnel to ground based radar, based on Fluent software platform and standard k-e turbulence model. Several key technologies were introduced in detail, including model building and mesh plotting. For practical examples, the simulation result of numerical wind tunnel was compared and validated with experiment result. It was indicated that the numerical wind tunnel technique can predict the wind resistant coefficient correctly, its simulation error was kept in acceptable range, and numeralization of the wind tunnel test for ground based radar system is feasible. At last, it was prospected the future of numerical wind tunnel for ground based radar.
