      다국어 초록 (Multilingual Abstract)

      A rotating machine, such as a gas turbine, Leakage is important in efficiency. Despite proper design of seal, wear and rub-grooved shapes occur on rotor or stator during operation. Clearance is important parameter in leakage of labyrinth seal but the worn shape increases clearance and leakage. This study is about the leakage characteristic of groove shape in width and depth directions. Numerical analysis of 3D geometry is conducted using ANSYS Fluent 15.0, and the results are shown using the discharge coefficient. when grooves occur at the smaller clearance, leakage increases considerably as compared with other cases. The minimum clearance can be expressed by the initial clearance and length of width and depth. As a result, Leakage characteristic depend on where the minimum clearance is located.
