Abstract in Portuguese
Apresenta um estudo sobre a economia de energia que se pode obter em transportadores pneumáticos de sólidos, através da implementação de um sistema de controle ativo do regime de escoamento. Analisa diferentes vazões de sólidos e ar em um circuito experimental com seção de testes de 45 milímetros de diâmetro interno, linha de transporte de 12 metros na horizontal e 9 metros na vertical, utilizado para transportar sementes de Setaria italica. Os resultados mostram que a técnica proposta permite reduzir em cerca de 50% o consumo médio de energia

Abstract in English
This work presents a study of possible energy savings in a pneumatic conveyíng system by the use of active control of the flow regime. Experimental tests were performed on a pneumatic circuit at the Thermal and Fluid Engineering Laboratory, having 45 mm ínner diameter pipe, 12 m horizontal line and 9 m vertical line transport, using Setaria itálica seeds. The resulís show that reductions in power consumption can reach 50% when compared with classical non controlled transport
