随着发动机性能的提升，涡轮进口温度已远超材料熔化温度，传统的内部冷却结构如针肋、表面凹陷和扰流肋等已经逐渐无法满足涡轮叶片冷却需求。本文提出一种基于反应-扩散系统的自组织几何生成方程，通过对方程参数的调整生成不同的换热结构，并通过CFD模拟对其流热性能进行评估。结果显示，通过该方程生成的结构相比传统针肋结构具有更高的三维自由度，并且通过结构的生长能更有效的控制流体分配，消除流动死区，从而有效地提升温度均匀性。

As engine performance continues to advance, turbine inlet temperatures have surpassed the melting point of conventional materials, rendering traditional internal cooling structures, such as pin fins, cavities, and turbulence ribs, insufficient for turbine blade cooling. This paper introduces a self-organized geometric generation equation based on a reaction-diffusion system. By adjusting the equation parameters, various heat exchange structures are generated, and their fluid-thermal performance is evaluated through CFD simulations. The results indicate that the structures generated by this equation exhibit a higher degree of three-dimensional freedom compared to traditional pin fin configurations. Moreover, the structural growth enables more effective fluid distribution control, eliminating flow dead zones and significantly enhancing temperature uniformity.
