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.
