    Automatic CFD analysis method for shape optimization
    (Universidad EAFIT, 2007) Giraldo Arias, Santiago; García Ruíz, Manuel Julio
    This project presents an Automatic Computational Fluid Dynamics (CFD) analysis method for shape optimization of an aerodynamic profile -- It begins with an overview of basic concepts on shape optimization, geometry parameterization and objective functions -- It continues with an introduction to the current status of CFD simulation software and types of solvers -- Then expands to optimization based on CFD analysis -- Following, a CFD-based method to optimize aerodynamic profiles under certain restrictions and scenarios is proposed -- Finally, the code implemented to automatically modify a profile bound by a set of control points based on CFD analysis is described -- The project was developed entirely at the EAFIT University’s Applied Mechanics Laboratory in Medellin, Colombia and is part of a collaboration effort in companionship with the University of Aberta in Canada and Los Andes University in Bogota, Colombia

    Topology and Shape optimization for CFD-Computational Fluid Dynamics
    (Universidad EAFIT, 2014) Betancur Valencia, Esteban; García Ruíz, Manuel Julio
    On this work a CFD optimization problem is treated from two different points of view -- In one hand, topology optimization using a homogenization method based on the Brinkmann penalization is presented, implemented using the finite elements method and optimized with a mesh adaptation step -- Secondly, a shape optimization method based on Hadamard boundary variation using differentiation with respect to the domain is developed, imple- mented and tested -- Finally, a coupling of both methods taking advantage of their own attributes is proposed and tested -- The expected results are obtained
