Abstract This article deals with the development of an implicit and conservative method for conjugate heat transfer at solid-fluid interfaces. The technique is applicable for both conformal and non-conformal meshes. The method, which is implemented within a fully coupled in-house code, is symmetric in its treatment of the solid and fluid regions and is shown to be very robust for highly complex configurations. To demonstrate the performance of the method, two compressible turbulent conjugate heat transfer test cases, the Mark II and C3X with film cooling, which are benchmarks for simulating the hydrodynamic and thermal fields around and inside turbine blades, are used. Numerical results generated are in good agreement with available experimental measurements.

一种全隐式共轭传热方法

摘要 本文讨论了固-流界面共轭传热的隐式和保守方法的发展。该技术适用于共形和非共形网格。该方法在完全耦合的内部代码中实施,在处理固体和流体区域时是对称的,并且对于高度复杂的配置显示出非常稳健。为了证明该方法的性能,使用了两个可压缩湍流共轭传热测试案例 Mark II 和 C3X 薄膜冷却,它们是模拟涡轮叶片周围和内部的流体动力和热场的基准。产生的数值结果与可用的实验测量非常一致。
