:Through establishing control parameters from outside to inside, the parametric design of air-cooled turbine blade based on airfoil has been implemented. On the basis of quickly updating structural features and generating solid model, a complex cooling system is created. Different flow-through units are modeled into a complex network topology with series and parallel connection. By applying one-dimensional flow theory, a program is composed to get the pipe network physical quantities along the flow path, including flow rate, heat transfer, pressure loss, temperature and other parameters. These parameters of inside units set as the inner boundary conditions, transmitted to the external flow field calculation program HIT-3D by interpolation to achieve thermal coupling analysis of full flow field. Referring studies in the literature to verify the effectiveness of pipeline network program and coupling algorithm. After that, on the basis of modified design calculation, and with the help of iSIGHT-FD, an optimization platform is established. Through MIGA optimization mechanism, the target of enhancing cooling efficiency is reached, and the heat load has been effectively reduced. Research work has a certain significance for rapid deploying the cooling structure design.
