Multipoint and Multi-Objective Aerodynamic Shape Optimization
A gradient-based Newton–Krylov algorithm is presented for the aerodynamic shape optimization of singleand multi-element airfoil configurations. The flow is governed by the compressible Navier–Stokes equations in conjunction with a one-equation transport turbulence model. The preconditioned generalized minimal residual method is applied to solve the discrete-adjoint equation, which leads to a fa...
متن کاملMulti-Winglets: Multi-Objective Optimization of Aerodynamic Shapes
Various configurations of aircraft wing tip devices have been investigated by performing 3D aerodynamics analysis. The wing tip device in this study was derived from the wing tips of a soaring bird, featuring three smoothly blended elements. Each multi-winglet configuration was integrated into a complete wing-tail-body aircraft configuration. Geometry of each of the three elements in the multi-...
متن کاملMOEICA: Enhanced multi-objective optimization based on imperialist competitive algorithm
In this paper, a multi-objective enhanced imperialist competitive algorithm (MOEICA) is presented. The main structures of the original ICA are employed while some novel approaches are also developed. Other than the non-dominated sorting and crowding distance methods which are used as the main tools for comparing and ranking solutions, an auxiliary comparison approach called fuzzy possession is ...
متن کاملComponent-Based Vapor Compression Simulation Tool With Integrated Multi-Objective Optimization Routines
A component-based simulation tool for modeling the steady state performance and cost of vapor compression systems has been developed. Features of the simulation software include component inter-changeability, charge management, and built-in multi-objective optimization routines. The simulation tool is capable of optimizing for a variety of performance or economic variables by varying any compon...
متن کاملmulti-objective optimization of hydropwoer multi-objective optimization of hydropower reservoirs operation based on the pattern of PAB markets
In recent years, the structure of the electricity industry has undergone a change and since November 2003, when the electricity market of the country was launched, its monopoly structure has become a competitive structure. In this market, the forecast of electricity prices is not only necessary in pricing but also plays an important role in finding the optimal operation strategy by the power pl...
