Optimization of piston for diesel engine using Kriging model

Diesel engine combustion chamber which reduces exhaust emission has been designed using CFD analysis and optimization techniques. In order to save computational time for design, the Kriging model, one of the response surface models, is adopted here. For the robust exploration, both the estimated function value of the model and its uncertainty...

Multi-objective design exploration using efficient global optimization

Multi-Objective Design Exploration (MODE) and its application are presented. MODE reveals the structure of the design space from the trade-off information and visualizes it as a panorama for Decision Maker. As an optimizer for MODE, Efficient Global Optimization (EGO) based on the Kriging model has been extended to Multi-EGO to solve multi...

Multidisciplinary design optimization of wing shape with nacelle and pylon

A Multidisciplinary Design Optimization (MDO) system for a wing with nacelle and pylon is developed. The present MDO system is based on the integration of Computational Fluid Dynamics (CFD) codes and NASTRAN based an aeroelastic-structural interface code. The Kriging model is employed to save the computational time of objective function...
