摘要
针对高功率径向线阵列天线在无压差工况下的泄漏模型,采用"当量面积"法对密封结构等效处理,利用基于有限体积法的仿真软件对泄漏过程进行数值模拟,并通过气密性实验验证。研究表明数值模拟和实验趋势一致,证明数值模拟的正确性,且具有速度更快、更节约成本及能获得内部气体参数分布等特点。
For the leakage model of high-power radial line array antenna in no pressure difference conditions,＂equivalent arca＂ method is used to equal the seal structure.Numerical simulations are carried out on the leakage process by using software which is based on the finite volume method,and the results are verified by the tightness experiment.Researches show that the numerical simulations are consistent with the experimental trends,proving the correctness of the numerical simulation.The numerical simulation is faster,more cost-effective and can obtain internal gas parameter distribution.
