Optimization of a double sided centrifugal pump
Centrifugal pumps are widely used in industrial applications. Compared to single-entry centrifugal pumps, double-sided pumps allow transportation of greater flow rates due to smaller proneness to cavitation, and offer counter-balancing of axial hydraulic forces due to double-entry design. In turbomachines, usually multiple objectives have to be optimized.
Innovative Computer Aided Solidification Technology
ERGOLINES and ESTECO teamed up to elaborate this new technology for 'assisted solidification' of steel to improve further the quality of the final product. The goal is to optimize the stirrer parameters and reduce internal and surface defects, increase product homogeneity and minimize energy consumption.
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.
Prediction of flammability limits for ethanol-air blends by the Kriging regression model and response surfaces
Flammability limits must be identified in order to assess and control handling risks of particular processes according to combustion product composition and environmental conditions. The present paper aims to present a model that can predict flammability limits for ethanol-air blends with at different moisture concentrations by Kriging interpolation techniques.
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.
White Paper | Aerodynamic Design Best Practices Using PowerFlow and modeFRONTIER optimization
The example in this paper is an aerodynamic guidance study of a generic SUV-type vehicle. The goal was to understand the impact of rear end design changes to provide guidance for achieving minimized drag, while also considering rear lift and side force fluctuations. The project was conducted on ExaCLOUD, which provided secure, web-based access to the complete Exa simulation software suite and modeFRONTIER.
ESTECO webinar recording | Exploiting Design of Experiments (DOE) techniques for multibody and structural vehicle analysis with modeFRONTIER, Adams and MSC Nastran
On August 29th, 2017 ESTECO hosted expert engineers from MSC Software who demonstrated the advantages of the integration of their software in modeFRONTIER workflow to identify better solutions using Design of Experiment for multibody and structural vehicle analysis.
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.
Vehicle steering pull - from product development to manufacturing
The objective of this paper is to propose a novel method to evaluate the impact of dimensional variations on vehicle steering pull. The proposed method combines Monte Carlo simulation to validate the dimensional tolerances, a multibody software to simulate initial data and modeFRONTIER to create a polynomial response surface and simulate the Vehicle Residual Aligning Torque (VRAT) distribution curve, final directional vehicle trend, and factors influence on VRAT.
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.
