使用名为 ARCFLO3 的新 Navier-Stokes 代码模拟分段缩颈式电弧加热器中的流场。通过将计算结果与 NASA 艾姆斯研究中心 20 和 60 MW arcjet 设施中获得的现有实验数据进行比较，评估 ARCFLO3 中采用的辐射和湍流模型的有效性。将电弧电压、加热器效率、质量平均热函、腔室压力、壁面热通量以及电弧射流中心线区域的总热函的计算数据与实测数据进行比较
The flowfields in segmented constrictor-type arc heaters are simulated using a new Navier-Stokes code named ARCFLO3. The validity of the radiation and turbulence modeling employed in ARCFLO3 is assessed by comparing the calculated results with the existing experimental data obtained in the 20 and 60 MW arcjet facilities at NASA Ames Research Center. Comparison is made between the calculated and the measured data for arc voltage, heater efficiency, mass-averaged enthalpy, chamber pressure, heat flux at wall, and total enthalpy in the centerline region of an arcjet flow
