Este trabalho apresenta um novo esquema upwind de alta resolução construído com base no conceito das curvas de Bézier que satisfaz diversos critérios de estabilidade no contexto da solução numérica de problemas de transporte dominado por convecção na dinâmica dos fluidos computacional. O esquema foi testado resolvendo os problemas da advecção linear e o problema de Burgers viscoso. Os resultados dessas simulações sugerem que o esquema proposto é uma alternativa atraente para problemas dominados por convecção quando comparado com outros esquemas da literatura.
