Acesso em:.https://repositorio.ufpa.br/handle/2011/5065The transport velocity is one of the most important parameters in the pneumatic transport of solids. The success of the particulates materials conveying depends on the prediction or the determination of the minimum velocity of transport. The velocity above of that necessary to the steady transport of solid particles leads to a great energy consumption due to an increased pressure drop of the system, solids degradation and abrasion of solids and of the tube. On the other hand, a velocity below of this boundary-value certainly will result on the deposition of solid particles for bottom of the tube and its consequently blockage. In this work, a technique to measure the minimum pickup velocity of solid particles in horizontal pneumatic conveying has been developed. It is based on visual observation of the particles behavior when occurring the capture, on measures of the velocity of operation of the gas and the mass of captured particles. The qualitative analysis of some parameters is made still that influence in the pickup velocity of particles, allowing a bigger understanding of the involved phenomena.porAcesso AbertoTransporte pneumáticoVelocidade de capturaDiâmetro de partículaPneumatic transportCapture speedParticle diameterDissertaçãoCNPQ::ENGENHARIAS::ENGENHARIA MECANICA::FENOMENOS DE TRANSPORTE::MECANICA DOS FLUIDOS
