摘      要：Adjoint-based optimization method is a hotspot in ***,this paper presents principles of adjoint method from Lagrange multiplier ***,combining a continuous route with thin layer RANS equations,we formulate adjoint equations and anti-physical boundary *** to the multi-stage environment in turbomachinery,an adjoint interrow mixing method is *** techniques of solving flow equations and adjoint equations are almost the same,and once they are converged respectively,the gradients of an objective function to design variables can be calculated using complex method ***,integrating a shape perturbation parameterization and a simple steepest descent method,a frame of adjoint-based aerodynamic shape optimization for multi-stage turbomachinery is *** last,an inverse design of an annular cascade is employed to validate the above approach,and adjoint field of an Aachen 1.5 stage turbine demonstrates the conservation and areflexia of the adjoint interrow mixing *** a direct redesign of a 1+1 counter-rotating turbine aiming to increase efficiency and apply constraints to mass flow rate and pressure ratio is taken.
