  Modeling rarefaction effects for the Navier-Stokes equations using artificial intelligence on the database generated via Direct Monte Carlo Simulation, Descrição: The main goal of this project is to use machine learning and artificial intelligence (AI) to identify terms that adjust the Navier-Stokes equations for modeling rarefied gasses. Achieving this objective will enable accurate computation of rarefied flows using Eulerian methods, i.e., based on continuum mechanics. The significant advantage of these methods is their reduced computational cost compared to Lagrangian methods, such as Direct Simulation Monte Carlo (DSMC), which is commonly used to obtain reliable data on rarefied gasses. The development of these models will enable accurate and less computationally demanding modeling of rarefaction effects, a topic of great interest to strategic areas such as the development of nano- and micro-technologies, atmospheric reentry vehicles, vacuum manufacturing processes, and modeling complex problems such as flows in porous media and chemical reactions, among others. , Situação: Em andamento; Natureza: Pesquisa. , Integrantes: Rodrigo Cassineli Palharini - Integrante / Leonardo Santos de Brito Alves - Coordenador / Israel Sebastiao Borges - Integrante / Malú Grave - Integrante / Jean Ribeiro - Integrante., Financiador(es): Conselho Nacional de Desenvolvimento Científico e Tecnológico - Auxílio financeiro.

  Fomento a la Vinculación Internacional para Instituciones de Investigación Regionales (Project No. FOVI210025): Strengthening Aerospace Engineering in Chile: a Collaboration Between USM, UChile, FACH, and INPE, Descrição: The National Satellite System (SNSat) will lead Chile to a world-renowned position in the development of aerospace technologies. With SNSat, Chile has the opportunity to enter a small group of countries that produce satellites and the development of such technologies could boost the national industry and the scientific production by universities and research centers. The development of these technologies in Chilean soil can reduce the country's dependence on accessing costly data to monitor natural resources such as forests, water reservoirs, mining, and control the borders and monitor the sea against invading boats. In addition, the global aerospace sector is expected to grow from $298.0 billion in 2020 to $430.9 billion in 2025 at a rate of 7.7%. An established national aerospace industry could generate a new income source, derived from the production of high-tech aerospace products and services. In order to achieve these goals, it is of fundamental importance to train engineers and scientists during the development phase of the SNSat and retain this knowledge in Chile. The training can be done in collaboration with institutions and companies willing to share their expertise gained over several years of investments and the development of aerospace technologies.. , Situação: Concluído; Natureza: Pesquisa. , Integrantes: Rodrigo Cassineli Palharini - Coordenador / Antonio Fernando Bertachini de Almeida Prado - Integrante / Maria de Fátima Mattiello Francisco - Integrante / Marcos Diaz - Integrante., Financiador(es): Agencia Nacional de Investigación y Desarrollo - Auxílio financeiro.

  FONDECYT de Iniciación en Investigación (Project No. 11190068): Aerothermodynamic Analysis of Inflatable Aerodynamic Decelerators for CubeSats Reentry and Recovery, Descrição: The design and development of a platform capable of surviving the atmospheric entry is challenging problem. Special care has to be taken so that the entry vehicle can decelerate sufficiently and dissipate the large heat load experienced from traveling through the atmosphere. With the advance of manufacturing processes and the development of flexible high-temperature materials, a new trend has emerged: the use of Inflatable Aerodynamic Decelerators (IAD). IAD technology is of great interest because such devices inflate to their full size in space and are not directly constrained by the launch vehicle payload shroud diameter like rigid aeroshells, nor inflation conditions like parachutes. The objective of this project is to investigate the impact of rarefied hypersonic reacting and non-reacting gas flows over three different configurations of inflatable aerodynamic decelerators using the DSMC method. The correct understanding of the aerodynamic forces and heating fluxes have a direct impact on the development of IAD systems for CubeSats reentry and recovery. The primary goal of this project is to investigate the influence of chemical reactions on the flowfield structure, aerodynamic properties, shock wave structure, as well as the wake region formed downstream of the vehicle. Numerical simulations will be performed for IAD at different reentry points.. , Situação: Concluído; Natureza: Pesquisa. , Alunos envolvidos: Doutorado: (1) . , Integrantes: Rodrigo Cassineli Palharini - Coordenador / Raffaele Savino - Integrante., Financiador(es): National Fund for Scientific and Technological Development - Auxílio financeiro.

  Projeto FAPESP (Processo No. 2014/25438-1): Numerical Investigation of Hypersonic Vehicles under Thermochemical Non-Equilibrium Conditions, Descrição: During the reentry of a reusable space vehicle in the upper atmosphere, a shock wave forms in front of the spacecraft and leads to a very high translational, rotational, and vibrational temperatures in the flowfield. A large amount of nitrogen and oxygen molecules are dissociated under these conditions and considerable reduction on the shock wave temperature and standoff distance is observed. In this way, the purpose of this investigation is to shed light on the role of thermochemical nonequilibrium in rarefied hypersonic flows around the SARA (acronym for Satelite Recuperável Atmosférico) capsule, which has been under development by Instituto de Aeronáutica e Espaço, at Departamento de Ciencia e Tecnologia Aeroespacial (DCTA). , Situação: Concluído; Natureza: Pesquisa. , Integrantes: Rodrigo Cassineli Palharini - Integrante / Craig White - Integrante / João Luiz F.

  Newton Research Collaboration Programme (Processo No. NRCP1415/2/6): Aerothermodynamic Characterisation of a Microgravity Experiment Platform's Re-entry Module, Descrição: A small ballistic re-entry vehicle named SARA (Satélite de Reentrada Atmosférica) is under design by the DCTA/IAE with the aim of performing experiments in microgravity environment for a time period of up to 10 days. Once the experiments are complete, it is necessary to guarantee the safe return of the capsule so that the results can be obtained and analysed on the ground. Aerothermodynamic calculations are necessary to accurately design and fabricate a lightweight heat shield for the SARA capsule so that it can survive the harsh re-entry environment. During the reentry chemical reactions may occur playing a vital role on the capsule's aerothermodynamic predictions. The main goal of this join project (Institute of Aeronautic and Space/University of Glasgow) is the implementation of ionization reactions using a quantum-kinetic chemistry model approach as a natural extension to the 5 species air chemistry model previously implemented in the dsmcFoam code by Dr. Palharini and Dr. White. The extended set of chemical reactions will be used to characterize the aerothermodynamic loads experienced by the SARA capsule during the stages of re-entry where the surrounding atmosphere is rarefied.. , Situação: Concluído; Natureza: Pesquisa. , Integrantes: Rodrigo Cassineli Palharini - Integrante / Craig White - Coordenador.

  European Space Agency (ESA) project : Demise of spacecraft and satellite debris during atmospheric reentry, Descrição: In the last decade several methodologies have been developed in order to study the demise of spacecraft and satellite debris during atmospheric reentry. In order to avoid ground risks, re-entry space debris are analysed based on computational, experimental, and analytical methods and the estimation of the quality/uncertainties of such tools are of extreme importance. Being too conservative in the risk assessment demand an economic burden to the aerospace industry and a too low risk increase the real threat to the population. The first objective of this project is to determine and improve the overall quality of these tools by inter comparison of the results generated by Universities and Research Institutes under this ESA project.

  Projeto FAPESP (Processo No. 2007/57673-6): Numerical investigation of aerothermodynamic in a reentry vehicle with surface discontinuities-like cavity, Descrição: In the design and development of hypersonic vehicles, knowledge of the factors affecting the thermal and mechanical loads acting on the vehicles are extremely important. Generally, engineers assumes that the vehicle has a smooth surface. However, discontinuities like cavities, gaps and steps are often present on the surface of such vehicles due manufacturing tolerances, sensor installation, spacing between the thermal protection system (TPS) plates or even to the difference of expansion rates of different materials that compose the TPS. In this scenario, this research project aims to investigate the impact of surface discontinuities on the flowfield structure and aerodynamic properties acting on hypersonic vehicles. Such discontinuities was investigated assuming a hypersonic flow over a flat plate with cavities with length-to-depth ratio (L/D) of 1, 2 3 and 4. , Situação: Concluído; Natureza: Pesquisa. , Alunos envolvidos: Mestrado acadêmico: (1) . , Integrantes: Rodrigo Cassineli Palharini - Integrante / Wilson F.
