Recent developments in numerical simulations in the aerodynamics field are focused on reducing the computational cost of the solvers, targeting their use at the initial design steps. Under the right assumptions, potential solvers can be exploited to accomplish a valid solution of the flow field for streamlined bodies in subsonic and close to transonic flows. A fully embedded approach to solve the full-potential equation is presented, where both the geometry and the wake are defined implicitly with a level set function. Embedded methods allow simplifying the mesh generation process, as only a background mesh is required to perform the analysis. The presented method gives an automatic and fast option to solve subsonic flows, which is especially desirable in optimization workflows.

一种求解有限元全势方程的嵌入式方法

空气动力学领域数值模拟的最新发展侧重于降低求解器的计算成本,目标是在初始设计步骤中使用它们。在正确的假设下,可以利用潜在的求解器来为亚音速和接近跨音速流动的流线体完成流场的有效求解。提出了一种解决全势方程的完全嵌入式方法,其中几何和尾流均使用水平集函数隐式定义。嵌入式方法允许简化网格生成过程,因为执行分析只需要背景网格。所提出的方法提供了一种自动且快速的选项来解决亚音速流动,这在优化工作流程中尤其理想。
