Risk Mitigation for Unmanned Air Vehicles Mission Planning

The present work (developed into the co-funded project “TAKE-OFF - Test and Knowledge-based Environment for Operations, Flight and Facility”, whose frame is the “Cluster Tecnologici Regionali - SmartPuglia 2020, Regione Puglia”) introduces a path planning methodology where the risk related to UAV operation is reduced by estimating the probability of hitting a person on the ground, assuming a map of the population density in the area interested by the flight is available. 

Effective toolchain for the model based development of an EUVI exhaust aftertreatment system

BASF, as a leading global catalyst supplier, was approached by a commercial truck manufacturer to improve cost and performance of the current EUVI production exhaust after treatment system.

ESTECO webinar recording | Shroud Design Exploration using PowerFLOW integrated with modeFRONTIER

ESTECO and EXA hosted a joint webinar on December 14th 2017, presenting the successful integration of PowerFLOW simulation technology in the modeFRONTIER workflow to provide Ditch Witch® with valuable insight to guide the shroud design on one of its Vacuum Excavators.

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. 

Sensitivity analysis of the dynamic response of an electronic fuel injector regarding fuel properties and operating conditions

Electronic fuel injectors play an indispensable role in High Pressure Common Rail (HPCR) fuel injection systems and interest numerous researchers to improve their performance. This paper investigates the sensitivity of three fuel properties (the fuel density, bulk modulus and absolute viscosity) to the valve opening/closing delay and the valve opening/closing time.​

Sensitivity analysis of urban morphology factors regarding solar energy potential of buildings in a Brazilian tropical context

Planning the urban morphology of the built environment is a key issue in shifting to a climate adapted urban environment. This paper addresses an important threefold energy challenge of tropical cities: the major potential of harnessing solar energy as renewable resource for local electricity production and the energy-saving paradox of reducing the undesirable solar heat gains in buildings while providing satisfactory levels of daylight. It aims at measuring the effect size of urban form factors regarding these energy goals.

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.

Optimization on Fuel Injection Parameter of Heavy-Duty Diesel Engine Based on Multi-Objective Genetic Algorithms

By using the GT-power software to establish the computing model of diesel engines and employing the modeFRONTIER multiobjective genetic algorithm (MOGA), this study carried out optimal research on performance indicators of diesel engines such as BSFC, NOX, soot, HC and CO, achieved the optimal solution to combination of injection parameters, and analyzed the relationship between optimal objective and fitness.​

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. 

Knowledge-Based Integrated Aircraft

A multidisciplinary optimization framework connecting the geometric model, aerodynamic model and structural model is performed on a wing shape with predefined loads on the wing. For global optimization, MOGA is used and for local optimization Simplex algorithm is used as the design variables are continuos.
