Analysis of Air Flow and Heat Transfer Characteristics in Finger Seal Structure

CAO Jing,JI Hong-hu,JIN Feng,CAO Guang-zhou(College of Energy and Power Engineering,Nanjing University of Aeronautics and Astronautics Nanjing 210016,China)  
The characteristics of air flow and heat transfer in finger seal structure was studied.The calculation model was built by the seal group area as porous media and heat source as frictional heat.The calculation results show that the maximum temperature of the seal area occurs in the contacting surface between finger-boots and rotor.The maximum temperature increases with the increased interference while differential pressure and speed;the maximum temperature decreased,while differ pressure increase in the interference and pressure.The results can be used to guide finger seal geometry design,contact-pair material selection and interference fit.
