摘要	The optimal design of the regenerative cooling system to improve the comprehensive heat transfer performance has been a long-term interest for researchers. It is essential to develop practical solution to optimize the cooling structure. The novel method of cooling structure optimization based on the calculus of variations has been developed. The average temperature, temperature inhomogeneity and coolant flow pressure loss were chosen as objective functions. The cooling channels can be established depends on geometric boundary conditions and thermal boundary condition of the structure, then the three-dimensional simulation of fluid/solid coupling field was calculated to get the temperature distribution of the cooling structure, the loss pressure, etc. Compared with the regualr optimization, the results show that the optimization of cooling structure based on the calculus of variations improves the cooling efficiency: the average temperature decreases, the temperature inhomogeneity drops, although the loss of pressure rises. © 2019, American Institute of Aeronautics and Astronautics Inc, AIAA.
