While design optimization has been widely used in the aerodynamic design in the last decades, its incapability to efficiently obtain applicable solutions has seriously limited its utilization potential. The proposal and utilization of so-called "man-in-loop" methodology (to use expert's experience to interfere the optimization process) in supercrit...

A compressor blade integrated with circumferential groove casing treatment (CGCT) is optimized in this study. A hybrid aerodynamic optimization algorithm that combines the differential evolution with a radial basis function response surface is used for the multi-objective optimization via the computational fluid dynamics analysis. The sweep and lea...

Pressure distribution is important information for engineers during an aerodynamic design process. Pressure Distribution Oriented (PDO) optimization design has been proposed to introduce pressure distribution manipulation into traditional performance dominated optimization.In previous PDO approaches, constraints or manual manipulation have been use...

This paper aims at optimizing a Turbine Based Combined Cycle (TBCC) nozzle for upgrading its aerodynamic performance in multiple flight conditions. An in-house RANS solver called NSAWET is employed for aerodynamic evaluation. The optimizer is a differential evolution algorithm combined with a response surface. Firstly, a two-dimensional model of th...
