Toward Gradient-Based Optimization of Full Gas Turbines

Optimization the Efficiency of Gas Turbines for Air Pollution Reduction

Increasing concerns about energy and emissions from fuel consumption in gas turbines has attracted many researchers to protect the environment and reduce pollutants in the world. The main objective of this paper is to investigate the increasing efficiency of three-stroke gas turbine operation based on the technical analysis of the operation of three-axis gas turbine cycles with non-design condi...

Multidiscipinary Optimization For Gas Turbines Design

State-of-the-art aeronautic Low Pressure gas Turbines (LPTs) are already characterized by high quality standards, thus they offer very narrow margins of improvement. Typical design process starts with a Concept Design (CD) phase, defined using mean-line 1D and other loworder tools, and evolves through a Preliminary Design (PD) phase, which allows the geometric definition in details. In this fra...

Performance Optimization of Gas Turbines Utilizing Four-Port Wave Rotors

Many studies have demonstrated the benefits of wave rotor application in gas turbine engines. The general performance trends have been generated; however, there is a question of where the most appropriate design space is. The aim of this investigation is to answer this question by showing the generalized performance trends of several four-port wave rotortopping configurations in a multi-dimensi...

Gradient-based Ant Colony Optimization for Continuous Spaces

A novel version of Ant Colony Optimization (ACO) algorithms for solving continuous space problems is presented in this paper. The basic structure and concepts of the originally reported ACO are preserved and adaptation of the algorithm to the case of continuous space is implemented within the general framework. The stigmergic communication is simulated through considering certain direction vect...
