摘要

对某重型燃气轮机的第一级透平静叶前缘气膜冷却特性进行了数值模拟研究

计算采用CFX5商业程序

主要研究了叶片前缘

尤其是滞止线附近的气膜冷却效果、传热及冷气喷射对气动性能的影响.通过对原始设计的计算结果进行分析

给出了针对静叶前缘气膜冷却结构的两种改进设计

得到的计算结果与原始设计相比

获得了更好的冷气覆盖效果.

Abstract

The numerical investigations on the leading-edge film cooling of an inlet guide vane were performed and described in this paper.The program CFX was employed to obtain the numerical solution.The original design was simulated to obtain flow and heat transfer characteristics of the leading edge film cooling.The film cooling characteristics and interactions between jets and mainstream around the leading edge

especially near the stagnation line

were analyzed in detail.To provide better coolant coverage around the leading edge

the cooling configuration was modified based upon the analysis and understanding of the 3-D prediction for the original design.The modified designs were compared with the original design

providing better coolant coverage around the leading edge.
