| Abstract: | The heat transfer characteristics of turbine casing was systematically studied by the numerical simulation and basic test, and the analysis method of heat transfer for the high pressure turbine casing was built. The main technology of casing heat transfer was summarized, CDF flow and heat transfer of casing key parts was analyzed, and the distribution law of casing surface heat-transfer was obtained. The analysis method of casing surface heat-transfer was corrected by test, and then the heat transfer engineering method of turbine casing was built by casing transient temperature analysis. |
