Novel cost effective configurations of combined power plants for smalls scale cogeneration from biomass design of the particle heat exchanger
A general design procedure have been developed for the application of the Immersed Particle Heat Exchanger to a novel, small scale, externally fired combined cycle capable of generating electrical and thermal power from carbon-neutral biomass. The Immersed Particle Heat Exchanger serves as the high temperature heat exchanger needed to couple the Brayton cycle with an external combustor of biom
Planform Dependency of Optimum Supersonic Airfoil for Wing-Body-Nacelle Configuration Using Multi-Fidelity Design Optimization
In this paper, supersonic wing design problems for supersonic transport (SST) with integrated engine intake and nacelle was discussed to obtain design knowledge of a supersonic airfoil with respect to wing planform dependency for a realistic configuration. Optimum wing designs were analyzed considering the interference between the engine intake, the nacelle, and the wing for two different planforms using a multi-fidelity design method.
Optimization of High lift device system deployment for takeoff performance
This work presents a proposed framework intended to be used for the optimization of highlift devices, namely Flaps and Slats for the present study. This paper addresses a first phase of a work aimed at a complete tool of high lift devices using modeFRONTIER as the optimizer in the process. The study takes into account the experience of a company inserted in the aeronautical environment and of the databases constituted from old aircraft.
Development of a Multidisciplinary Design Optimization Framework Applied on UAV Design by Considering Models for Mission, Surveillance, and Stealth Performance
This paper presents a Multidisciplinary Design Optimization (MDO) framework that is intended to be employed in the early design stages of Unmanned Aerial Vehicles (UAVs). A development approach for modeling the sensor performance and the radar signature is proposed and it is shown that their integration in a framework which also takes into account the geometry, the aerodynamics, the stability, and the mission simulation is feasible.
Aircraft conceptual design of a business jet (category Large) using Multidisciplinary Design Optimization techniques
A Multidisciplinary Design Optimization approach considering closed-loop flight control laws was applied to a conceptual design of a large-cabin business jet. The optimization algorithm used in this work is the Multi-Objective Genetic Algorithm of second generation (MOGA-II algorithm) using modeFRONTIER. Two types of analysis were done: mono-objective, maximizing the internal rate of return, and multi-objective, maximizing the internal rate of return and minimizing Dubai – London City mission block time.
design optimization and testing of high-performance motors
This article has reported on an industrial R&D project aimed at identifying a cost-effective response to the more and more challenging high-speed motor requirements that presently come from the gas industry sector. To meet the very high efficiency, dynamic performance, and reliability standards required by cutting-edge turbomachinery drive applications, a special PM synchronous motor prototype has been developed.
Innovations in a floating production system for optimizing costs
An optimization process using modeFRONTIER is implemented with the aim of optimizing the design of a floating production system with the minimization of installation and operating cost in mind. The hull form was designed using a genetic algorithm, taking into account 7 parameters, and focusing on minimizing steel weight.
Study of the impact of structural parameters on the dynamic response of an electronic fuel injector
The study concentrates on the effects of structural parameters of an electronic fuel injector on its dynamic response. The injector was developed for a marine medium-speed diesel engine. The dynamic response from the start of the control signal to the end of the needle valve closing was investigated. Firstly, a complete and detailed model of the electronic fuel injector was built and integrated into an optimization model, where a MOGA was applied.
How to optimize an external gear pump in highly constrained conditions
The objective of this project was to take a standard series gear pump with a displacement of about 20 cc/rev and to minimize its noise emission, while at the same time maintaining the same level of performance. The optimizer modeFRONTIER and simulator HygeSim are used to find the optimal configurations of the pump model.
