A Multi-Objective Factorial Design Methodology for Aerodynamic Off-Takes and Ducts

Fluid off-takes and complex delivery ducts are common in many engineering systems but designing them can be a challenging task. At the conceptual design phase system parameters open to consideration preliminary studies necessary instruct conceptualisation process an iterative development of ideas. This paper presents simple methodology parametrically design, explore optimise such at low cost. The method is then applied aerodynamic including off-take followed by duct. A selection nine input variables explored via fractional factorial approach that consists three individual seven-level cubic designs. Numerical predictions characterised based on multiple objectives. scaled representation these objectives allows for scalarisation technique employed form global criterion which indicates set trade-off geometries. leads nominal designs determination their robustness will eventually next iteration. results presented discussed space, variable space contours several flow quantities optimal
