Acesso em:.https://repositorio.ufpa.br/handle/2011/13701The present work aims to investigate the application of the Richardson Extrapolation (ER) method as an alternative to reduce the simulation time of a specific CFD problem, which is related to a convective and diffusive problem. The geometry under study was built in the Blender software. The initial and boundary conditions were set using the BlenderFDS program, the calculation was done with a CFD code called Fire Dynamics Simulator (FDS), the results were extracted with smokeview software. In addition, Richardson extrapolation code was developed in the Fortran programming language. Flow field properties such as specific mass, pressure, temperature and velocity were calculated for three mesh sizes with and without the RE method. The extrapolated results show promise for maintaining accuracy at a lower computational cost.Acesso AbertoAttribution-NonCommercial-NoDerivs 3.0 Brazilhttp://creativecommons.org/licenses/by-nc-nd/3.0/br/Extrapolação de Richardson - Redução de tempo - ComputaçãoPrograma Blender FDSTransferência de calorFluidodinâmica computacionalRichardson Extrapolation - Time Reduction - ComputationHeat transferComputational Fluid DynamicsAplicação da extrapolação de Richardson na otimização de problemas em fluidodinâmica computacionalApplication of Richardson extrapolation in the optimizing of computacional fluidodynamicsDissertaçãoCNPQ::ENGENHARIAS::ENGENHARIA DE PRODUCAOPROCESSOS INDUSTRIAISENGENHARIA DE PROCESSOS
