Optimization methodologies applied to the design of a gas turbine cooling system

The multi-objective optimization techniques were applied to a three-dimensional CFD model for the design of the cooling system of a gas turbine blade tip.A parametric CFD model of a high pressure rotor blade was developed in order to study the cooling efficiency in the tip area.

Multi Objective optimization of a car vehicle coupling modeFRONTIER and MDI-ADAMS

When designing the suspension system for a car, a compromise has to be found between several contrasting objectives. On the one hand, one wants to set the suspensions so that they allow an efficient and safe handling of the vehicle; on the other hand, comfort cannot be sacrificed too much.

Development of an integrated methodology for the holistic design and optimization of high speed roro - passenger vessels

Quite often during the preliminary ship design stage, the designer in search of the “optimal vessel” for a specified operation scenario is faced with a series of important decisions with crucial impact on the vessel’s performance. It is the nature of the designer’s work that requires many of these decisions to be made during the early stages, based usually on limited, vague or undependable information.

Optimisation techniques applied to the design of gas turbine blades cooling systems

This study is part of an AVIO project concerning the development of High Pressure Turbine blades with advanced cooling systems. Due to the high gas temperatures entering the turbine of the most recent aero-engines (in general up to 2000 K at the turbine inlet), a very efficient cooling system is required in order to maintain the metal temperatures below the allowable limits.

Design optimization of insulation usage and space conditioning load using energy simulation and genetic algorithm

Architectural design is a process to find the best solution to satisfy various design criteria. To achieve sustainable design, performance simulations are often used to verify these criteria and modify the design. The conventional trial-and-error approach of is too time-consuming. 

Automated Calibration of a Diesel Oxidation Catalyst

Due to the future worldwide emission regulations, the design of new engines is a growing challenge for all car manufacturers. Due to the complexity of modern power-trains, especially the basic development is strongly attended by means of simulation. In this study the software application modeFRONTIER was used to develop a "over all student chart".

Wing Optimization of regional aircrafts of Alenia Aermacchi by means of ModeFrontier

The scope of this work is the optimization of two different wings for the Green Regional Aircraft (GRA), with the aim to support preliminary design office during the definition of the most promising configuration. The main objectives of this work are: lowering fuel consumption and lowering the wing weight.

Multi-Objective optimization of front and rear crossbeams and crash-boxes for low speed bumper barrier tests

The presented methodology has the objective of optimizing a small vehicle archetype in the rear and front crossbeams and crash boxes. The FE model of the front and rear bumper system has been optimized using DOE and response surface methodologies.

CFD Analysis and Multi-Objective Optimization of a Diesel Engine for Automotive Applications

The goal of the study was to develop a light-duty common-rail engine with low emissions. The process consisted in an experimental analysis (including performance and acoustic tests and characterization of the fuel injection system), model configuration and validation and multi-objective optimization.

Environment-friendly aircraft stretches its wings with modeFRONTIER

In an ambitious collaborative venture, Alenia Aermacchi is heading the Green Regional Aircraft (GRA) design team of the The Clean Sky Joint Technology Initiative, committed to developing environmentally friendly aircraft. Domestic air travel of the future will meet demands for: weight reduction, aerodynamic efficiency, high level operative performance, compliance with emission standards, and respect of noise limits.
