Neste trabalho, são apresentados Métodos de Diferenças Finitas de Direções Alternadas (ADI) aplicados ao problema de escoamento de substâncias miscíveis em meios porosos com fontes singulares. Uma técnica de remoção de singularidades é apresentada como opção para a recuperação das taxas de convergência quadráticas típicas de problemas regulares. Resultados numéricos são apresentados comprovando as taxas de convergência preditas para a aproximação da pressão e ilustrando a aplicação da metodologia proposta na simulação do transporte de poluentes.References
