摘要

我们简要介绍了最常用的湍流模型及其验证结果。我们使用各种商业软件程序模拟了钝化球形锥体周围的高速流动。不同软件系统中的问题设置尽可能相互接近。锥体表面热通量密度的数值与实验数据进行了比较。我们证明了计算中存在的湍流对表面热通量密度值的影响。

Calculation of the Sphere–Cone Heat Transfer in a High-Speed Flow with Commercial Software

We present a brief overview of the most popular turbulence models and the validation results available for them. A high-speed flow around a blunted spherical cone is simulated using various commercial software programs. The problem setups in different software systems are as close to each other as possible. The numerical values of the heat flux density on the cone surface are compared with the experimental data. We demonstrate the influence of the turbulence present in the calculation on the value of the surface heat flux density.

期刊介绍： Fluid Dynamics is an international peer reviewed journal that publishes theoretical, computational, and experimental research on aeromechanics, hydrodynamics, plasma dynamics, underground hydrodynamics, and biomechanics of continuous media. Special attention is given to new trends developing at the leading edge of science, such as theory and application of multi-phase flows, chemically reactive flows, liquid and gas flows in electromagnetic fields, new hydrodynamical methods of increasing oil output, new approaches to the description of turbulent flows, etc.
