英文摘要：

The technique of the variation in the grid node coordinates combining with Jacobian Matrices are introduced to the establishment of the turbulent continuous adjoint method with the constant eddy viscosity assumption.This method reduces the derivation difficulty for the complex adjoint system of the RANS equations,which simplifies the formulas and saves the cost.Meanwhile,the constant eddy viscosity assumption and the Spalart-Allmaras turbulence model are employed to achieve the numerical validation for inverse design of 2D blade pressure distribution,and the gradients,optimization process and results are compared with the fully turbulent adjoint system.And with the objective of the entropy generation,a subsonic blade is tested with the numerical optimization and experiment of wind tunnel to demonstrate the reliability of the optimal results.
