Tandem blade technology has been developed for years due to its capacity to bear higher aerodynamics than conventional configurations. Even so, there is still the tough problem of how to design tandem blades effectively and further improve blade performance. This paper tries to further understand the flow characteristics of tandem blades in order to present a new method of designing them under subsonic inflow conditions. Firstly, efforts were made to reveal the aerodynamic interaction between the forward blade (FB) and the aft blade (AB). Secondly, considering this aerodynamic interaction, the design principles and the camber line modification method were put forward, with which typical controlled diffusion airfoil (CD airfoil) isentropic Mach number distributions can be achieved for both FB and AB. Lastly, the optimizations were conducted on a 2D tandem blade and a transonic compressor with a tandem blade, respectively. The computation fluid dynamic (CFD) results show that the optimized tandem blade achieves a significant improvement for both 2D blade performance and transonic compressor characteristics at low speeds.

According to the limitations of conventional method of optimization design for the process parameters in the hydroforming process, a new simulation method has been proposed for the optimization of the process parameters, which is the integration of the neighborhood cultivation genetic algorithm (NCGA) and the dynamic explicit algorithm based on finite element method (FEM). The new method has been adopted for the optimization of the hydroforming loading path of an instrument panel beam and the process parameters are the internal pressure vs. time and the axial feeding displacement vs. time. It is concluded that the acquired loading path through the new method is more optimal than the one through the trial and error method. In addition, the new method can simultaneously generate multiple Pareto-optimum solutions in one computation and provide more freedom for the designer's decision making of the process parameters.
