为研究环形燃烧室中边界层、黏性、湍流模拟方法对旋转爆轰流场结构的影响
采用开源计算流体动力学软件OpenFOAM
以氢气为燃料、空气为氧化剂
基于大涡模拟(Large Eddy Simulation
LES)方法、RANS方法、Euler方法
分别结合滑移和无滑移边界
对三维旋转爆轰发动机模型进行数值模拟
分析对比不同计算方法下旋转爆轰流场结构。着重讨论以LES方法得到的流场结构。研究结果表明:当采用滑移边界时内、中、外截面的流场温度无太大差异
当采用无滑移边界时内外壁面温度高于中间截面
边界层会影响近壁区域气体的流动速度
导致内外壁面爆轰波高度低于中间截面
还会影响燃烧产物的流动状态轴向截面上爆轰波波头产生变形;不同湍流计算方法得到的旋转爆轰流场结构存在相似性
黏性是影响旋转爆轰流场结构的主要原因。研究结果对于揭示边界层和黏性对旋转爆轰的影响机制具有一定的科学意义。
In order to study the characteristics of rotating detonation flow field in annular combustor and the effects of boundary layer
viscosity and turbulence simulation methods on the flow field structure
the open source computational fluid dynamics software OpenFOAM is used to simulate the three-dimensional model of rotating detonation engine (RDE) with hydrogen as fuel and air as oxidant. The characteristics of rotating detonation flow field obtained by Euler equation
large eddy simulation (LES) method and Reynolds-averaged Navier-Stokes (RANS) method are compared and analyzed. The flow field structure from LES simulation is emphatically discussed. The results show that the temperatures of flow fields in the inner
middle and outer sections exhibit no appreciable difference when the slip boundary is applied. However
when the no-slip boundary is utilized
the temperatures of the inner and outer walls are higher than that of the middle section
and the boundary layer will affect the flow velocity of gas in a region close to the wall. As a result
the height of detonation wave on the inner and outer walls is lower than that in the middle section. The boundary layer also affects the flow state of the combustion products
leading to the deformation of wave front on the axial section. The rotating detonation flow field structures obtained by different turbulence simulation methods are similar
indicating that the viscosity is the main factor affecting the rotating detonation flow field structure. The findings are highly significant in terms of elucidating the mechanism by which the viscosity and the boundary layer affect the rotating detonation process.

The effects of the coefficients of viscosity, diffusion, and thermal conductivity are included. The basic equations are set up for a gas in which the irreversible unimolecular reaction A→B takes place with the release of energy. The topological nature of the solutions is discussed and some detailed numerical solutions are given. The numerical calculations (obtained by a point-by-point integration of the detonation equations) indicate a strong probability that there is a highest ambient pressure above which a steady-state detonation cannot take place, and indicate a possibility that there is an ambient pressure below which a detonation cannot occur. In the examples considered, there is strong coupling between the reaction zone and the shock zone so that the solutions never come close to the von Neumann ``spike.'' If the Mach number is greater than unity, the solutions have an entirely different nature and exist for only a single ambient pressure rather than for a range of pressures. However, from hydrodynamical considerations, a detonation wave initiated from either a point or a fixed wall can become equivalent to the steady-state solutions only if the Mach number is greater than or equal to unity.

Our intention is to make it as easy as possible to develop reliable and efficient computational continuum-mechanics codes: this is achieved by making the top-level syntax of the code as close as possible to conventional mathematical notation for tensors and partial differential equations. Object-orientation techniques enable the creation of data types that closely mimic those of continuum mechanics, and the operator overloading possible in C++ allows normal mathematical symbols to be used for the basic operations. As an example, the implementation of various types of turbulence modeling in a FOAM computational-fluid-dynamics code is discussed, and calculations performed on a standard test case, that of flow around a square prism, are presented. To demonstrate the flexibility of the FOAM library, codes for solving structures and magnetohydrodynamics are also presented with appropriate test case results given. © 1998 American Institute of Physics.
