|Experimental and numerical research on heat transfer in the tip gap region of |

|a gas turbine blade, Jan 2011 - present. (sponsored by Solar Turbines |

|Incorporated) |

|Actions |

| |

|Mentor undergraduate student using SolidWorks (CAD software) to fabricate |

|squealer tip blade with a 3D printing technology, and to conduct the |

|mechanical safety inspection; |

|Guide Master degree candidate using infrared (IR) camera to record blade tip |

|heat transfer data, and to analysis the test results; |

|Instrument Thin Film Platinum gages to measure near tip region heat transfer |

|data. |

|Perform conjugate heat transfer simulation with CFD codes to analysis a |

|thermal protection scheme in the turbine blade tip gap region. (ANSYS-Fluent |

|was employed) |

| |

|Outputs |

|The heat transfer characteristics on the turbine blade tip and the near tip |

|region were mapped with the IR measurement data. The physics of the tip gap |

|flow, and its effect on heat transfer were explored. Different tip gap |

|dimensions were compared at multiple main flow Mach numbers, and suggestions |

|were proposed to protect the turbine blade tip from thermal damage. |

|The sponsor (Solar Turbine Inc.) was satisfied with the progress reports, and |

|decided to continuously support further research on tip gap flow with our lab.|

| |

|The results were summarized in the form of a conference paper, and were |

|submitted to the international conference of TURBOEXPO2013. |

| |

|Experimental and CFD investigation on film-cooling performance on gas turbine |

|blade and nozzle guide vane, Jan 2009 - Dec 2010. (sponsored by Solar Turbines|

|Incorporated) |

|Actions |

| |

|Design and set up film cooling test system in turbine cascade wind tunnel; |

|conduct the heat transfer measurement; Processed the data reduction. (Labview |

|codes were written for the DAQ process; Matlab codes were written for data |

|reduction) |

|Performed CFD study to investigate the detail physics on the shock/film |

|cooling interaction. (ANSYS-CFX was employed) |

|Performed Hot-wire probe measurement to determine the freestream turbulence |

|intensity in the linear cascade test section. |

| |

|Outputs |

|The heat transfer coefficient and film cooling effectiveness of a fan-shaped |

|hole injected gas turbine blade was recorded for the first time under a unique|

|flow condition. A novel phenomenon of shock/film cooling interaction was |

|observed in the experiment, and the physics were explored in the numerical |

|study. The suggestions were proposed to optimize the film cooling performance |

|on a gas turbine blade. |

|The sponsor (Solar Turbine Inc.) was satisfied with the final report, and |

|assigned new research projects to our lab. |

|A part of the research was summarized as a journal paper, which was accepted |

|by the ASME Journal of Turbomachinery. Two other journal papers were submitted|

|to the AIAA Journal of Propulsion. The experimental results were presented at |

|the conference of TURBOEXPO in Jun 2011, and AIAA conference in Jan 2012. |

|Determination of the pressure loss caused by the secondary flow in the linear |

|cascade model of a high turning blade with divergent endwall, Sep 2008 - May |

|2009. (sponsored by Siemens) |

|Actions |

| |

|estimation/safety check was done both manually and using SolidWorks for |

|special test conditions) |

|Conducted the five-hole pressure probe measurement and data reduction for the |

|total pressure loss determination. (3D interpolation method was coded in |

|Matlab to reduce the pressure data) |

|test section to perform multiple location measurement. |

| |

|Outputs |

|The pressure loss caused by the secondary flow at the exit of a gas turbine |

|blade cascade was determined into a 2-D contour map. The result was used to |

|optimize the geometry of the endwall contour in a gas turbine blade cascade. |

|The sponsor (Siemens) was satisfied with the progress report, and decided to |

|continuously support further research. |

|The results were presented at the conference of ASME 2010 3rd Joint |

|US-European Fluids Engineering Summer Meeting. |
