Abstract

In the present study, a discrete forcing Immersed Boundary Method (IBM) is proposed for the numerical simulation of high-speed flow problems including heat exchange. This class of tools is relevant for several applications in engineering studies for aerospace applications, notably for atmospheric reentry. The flow field is governed by the compressible Navier–Stokes equations, which are resolved by using the open source library OpenFOAM. The numerical solver is modified to include source terms in the momentum equation and in the energy equation, which account for the presence of the immersed body. The method is validated on some benchmark test cases dealing with forced convection problems and moving immersed bodies. The results obtained are in very good agreement with data provided in the literature. The method is further assessed by investigating three-dimensional high Mach flows around a heated sphere with different wall temperature. Even for this more complex test case, the method provides an accurate representation of both thermal and velocity fields.

可压缩流动传热数值模拟的离散浸入边界法

本文提出了一种离散强迫浸入边界法（IBM），用于包括热交换在内的高速流动问题的数值模拟。这类工具与航空航天应用的工程研究中的几个应用有关，特别是在大气再入方面。流场由可压缩的Navier-Stokes方程控制，该方程通过使用开源库OpenFOAM进行求解。对数值求解方法进行了改进，在动量方程和能量方程中加入了考虑沉体存在的源项。通过强制对流问题和运动沉体的基准测试，验证了该方法的有效性。所得结果与文献中提供的数据非常吻合。通过研究不同壁温的加热球体周围的三维高马赫数流动，进一步验证了该方法。即使对于这个更复杂的测试用例，该方法也提供了热场和速度场的精确表示。

期刊介绍： The European Journal of Mechanics - B/Fluids publishes papers in all fields of fluid mechanics. Although investigations in well-established areas are within the scope of the journal, recent developments and innovative ideas are particularly welcome. Theoretical, computational and experimental papers are equally welcome. Mathematical methods, be they deterministic or stochastic, analytical or numerical, will be accepted provided they serve to clarify some identifiable problems in fluid mechanics, and provided the significance of results is explained. Similarly, experimental papers must add physical insight in to the understanding of fluid mechanics.
