    • Boundary-layers integral analysis - Airfoil icing  (Trabalho apresentado em evento)

      Stefanini, Luciano Martinez; De Mattos Silvares, Otávio; Da Silva, Guilherme Araújo Lima; De Jesus Zerbini, Euryale Jorge Godoy (American Institute of Aeronautics and Astronautics Inc., 2008)
      Various classic icing codes have been developed and used by the aircraft manufacturers to predict the ice shapes evolution in non-protected airfoil surfaces. These codes apply boundary layer integral analysis, based on ...

    • Boundary-layers integral analysis - Heated airfoils in icing conditions  (Trabalho apresentado em evento)

      Da Silva, Guilherme Araújo Lima; De Mattos Silvares, Otávio; De Jesus Zerbini, Euryale Jorge Godoy (American Institute of Aeronautics and Astronautics Inc., 2008)
      Under icing conditions, it is necessary to heat and control the temperature of the airfoil surface at leading edge region to prevent ice formation. The thermal anti-ice system balances mainly the evaporative cooling effects, ...

    • Heat transfer on iced cylinders  (Trabalho apresentado em evento)

      Stefanini, Luciano Martinez; Silvares, Otávio de Mattos; da Silva, Guilherme Araujo Lima; de jesus Zerbini, Euryale Jorge Godoy (AIAA International, 2010)
      The convective heat transfer is the main mechanism to remove the solidification enthalpy during glaze ice accretion. Most of the airfoil icing prediction codes use a heat transfer calculation procedure based on the classical ...

    • Multiphysics modeling of wire-to-plate electrohydrodynamic drying with air crossflow  (Artigo de Periódico)

      Oishi, Tamires K.; Pouzada, Eduardo V. S.; Gut, Jorge A. W.; Raghavan, Vijaya (Springer Science and Business Media Deutschland GmbH, 2024)
      Electrohydrodynamic (EHD) convective drying is a non-thermal energy-efficient technology to preserve heat-sensitive materials by dehydration. A high-voltage electrode is used to induce corona wind that increases convective ...

    • Numerical and experimental modeling of thermal errors in a five-axis CNC machining center  (Artigo de Periódico)

      dos Santos, Marcelo O.; Batalha, Gilmar F.; Bordinassi, Ed C.; Miori, Gelson F. (Springer London, 2018)
      This work aims at the establishment of methodology to model and analyze the thermal errors of a five-axis CNC machining center, from an estimated temperature field, to finally model an artificial neural network (ANN) ...

    • Optimization loop based on adjoint sensitivity analysis for flows through porous media with adsorption  (Artigo de Periódico)

      Chieregatti, Bruno G.; Brasil Lima, João S.; Hayashi, Marcelo T.; Volpe, Ernani V. (John Wiley and Sons Ltd, 2022)
      In the past few years, the development of inverse design and optimization methods has opened up new possibilities. The adjoint method is of great significance in that context, since it permits high fidelity to flow-physics ...

    • Simulation of an airfoil electro-thermal anti-ice system operating in running wet regime  (Trabalho apresentado em evento)

      Da Silva, Guilherme Araújo Lima; De Mattos Silvares, Otávio; Zerbini, Euryale Jorge G. J. (2005)
      An airfoil electro-thermal anti-ice system operating in a running wet regime was mathematically modeled and simulated. The results were compared to experimental data and results from other numerical codes. For the regions ...
