چکیده
A novel parametric control method for the compressor blade, full-blade surface method, is proposed in this paper. Compared with traditional has good smoothness and construction convenience while maintaining low-dimensional characteristics, compared semi-blade a larger degree of geometric deformation freedom can account changes both suction pressure surface. only four more parameters each so it does not significantly increase optimization time. The effectiveness been verified aerodynamic field compressors by an case Stage35 (a single-stage transonic axial compressor) under multi-operating conditions. brought following results: adiabatic efficiency optimized blade at design speed 1.4% higher than that original one surge margin 2.9% higher, off-design speed, improved 0.6% 1.3%.

like any other learning activity, translation is a problem solving activity which involves executing parallel cognitive processes. the ability to think about these higher processes, plan, organize, monitor and evaluate the most influential executive cognitive processes is what flavell (1975) called “metacognition” which encompasses raising awareness of mental processes as well as using effectiv...
A Multifidelity Gradient-Free Optimization Method and Application to Aerodynamic Design
The use of expensive simulations in engineering design optimization often rules out conventional techniques for design optimization for a variety of reasons, such as lack of smoothness, unavailability of gradient information, presence of multiple local optima, and most importantly, limits on available computing resources and time. Often, the designer also has access to lower-fidelity simulation...
