学术成果 Academic Achievements My major academic achievement can be summarized as follows1. Develop the adjoint mixing plane method to extend the adjoint method (an efficient sensitivity analysis method) to turbomachinery blade shape optimization in a steady analysis with multiple blade rows(refs. 1 and 2. This work was part of my PhD research under the supervision of Prof. Li He).2. Apply the adjoint method for coupled blade aerodynamic and aeroelastic design optimisation(ref. 3. This work was part of my PhD research under the supervision of Prof. Li He). 3. Develop an improved mixing plane method for analyzing steady flow within multi-blade-row turbomachines(ref. 4).4. Develop numerical methods for stabilizing solution and accelerating convergence of time spectral equations(refs. 7 and 8).5. Develop a rotor-stator coupling method for solving time spectral equations in a multi-row domain(ref. 5).6.
