Performance of different optimization concepts for reactive flow systems based on combined CFD and response surface methods

Optimization of reactive flow systems, e.g. coal and biomass combustion, gasification or partial oxidation, is usually a multi-parameter problem, while geometry configurations (e.g. reactor dimensions, burner dimensions) and operating conditions (e.g. fuel mass flow, reactor temperature, cooling capability) mainly determine the process efficiency and profitability. 

Multivariate Optimization and 1-D Simulation of a High Performance Single Cylinder Engine for The ESTECO Academy Design Competition

Organized in partnership with Aprilia Racing and Gamma Technologies, the ESTECO Academy Design Competition 2016 was open to teams of undergraduate and graduate engineering students. The challenge was to improve the design of a 4 stroke single cylinder engine through multidisciplinary optimization (using modeFRONTIER) and 1-D simulation of the engine system with GT-Suite.

Situated Design Optimization of Haptic Devices

 It is a complex task to develop and optimize a high-performing haptic device, mainly because of the multi-domain and multi-criteria performance requirements for such devices.​ The general goal for the research presented in this paper is to further develop the previously proposed model-based framework and methodology into a situated and computationally efficient design framework for multiobjective optimization of haptic devices.

Design of ducted propeller nozzles through a RANSE-based optimization approach

Marine propellers design requirements are always more pressing and the application of unusual propulsive configurations, like ducted propellers with decelerating nozzles, may represent a valuable alternative to fulfill stringent design constraints. This study proposes an optimization approach for the design of the accelerating

Design and analysis of a new generation of CLT propellers

The researchers of University of Genoa, in collaboration with SISTEMAR SA, proposed a study to design and analyze a tip loaded propellers to improve full-scale propeller efficiency (lower fuel consumptions and lower emission levels to comply with environmental pollution regulations). The modified tip loaded propeller (a mix between a tip rake and a contracted and tip loaded propeller) is designed via an optimization strategy using a Boundary Elements Method (BEM), a custom parametric description of the unconventional blade geometry and an optimization algorithm within the modeFRONTIER environment.

A support approach for the conceptual design of energy-efficient cooker hoods

The design of a cooker hood concerns different aspects, such as the aesthetic design, thermal and structural analysis of components, fluid dynamics performance and energy consumption.​The scope of the proposed research is to evaluate the performance of a kitchen hood during the conceptual design in terms of energy efficiency to classify the product using the European energy label. An optimization analysis is proposed to enhance the design of products with reduced energy consumption.
