This paper aims at presenting an approach to structuring interactions within product, through a graph, for simulation purposes. This approach has been developed for specific needs on Simulation Lifecycle Management (SLM) dedicated to aircraft engine development. The paper also illustrates the implementation of this approach on a case study which concerns a compressor design.

The development of the airport segment faces environmental externalities especially related to the increase in emissions of Greenhouse Gases (GHGs) from combustion of fossil fuels by the aircraft engine, by the machinery for the maintenance of the planes and also by the vehicles used for passengers connections (private cars, taxicabs or public transportation system). In this scope, the current work presents the case study of the expansion of the Viracopos International Airport at Campinas – São Paulo, Brazil. To evaluate that, the methodology of the Intergovernmental Panel on Climate Change (IPCC) was implemented to estimate the emissions of GHGs by aircraft for the years 2008 (before expansion), 2012 (current picture) and 2016 (future scenario) observing the changes in demand for passengers and cargo transportation. To evaluate the emissions from the vehicles it was used the AIMSUN microsimulation software to estimate emissions in the years 2012 and to simulate sensitivity scenarios for the year 2016. It was found that the inventory of CO2 emissions for both types of transports considered for Viracopos airport showed similar orders of magnitude, what can be inferred about the equivalent contribution of these two modes on emissions of GHGs for the study area. These results may serve as a basis for establishing emission management plans of air pollutants by the competent organizations and to propose more targeted and effective measures to reduce the GHG emissions by these sources.

Computational Implementation

Studies of fluid-structure interactions associated with flexible structures such as flapping wings require the capture and quantification of large motions of bodies that may be opaque. As a case study, motion capture of a free flying insect is considered by using three synchronized high-speed cameras. A solid finite element (FE) representation is used as a reference body and successive snapshots in time of the displacement fields are reconstructed via an optimization procedure. One of the original aspects of this work is the formulation of an objective function and the use of shadow matching and strain-energy regularization. With this objective function, the authors penalize the shape differences between silhouettes of the captured images and the FE representation of the deformed body. A similar method with a three-dimensional voxel cloud (VC) reconstruction is also illustrated. Challenges faced in implementing the VC method are discussed and the current computational implementation will also be covered.
