This paper investigates the use of a new imaging system to measure the velocity and the mass flow distribution of fertiliser granules spread by a centrifugal device. The new acquisition system consists of a digital camera placed above the disc so that its view axis corresponds to the disc axle. This provides useful geometrical properties to develop a simple(More)
This article reports a new approach to measure the velocity and the mass flow distribution of granules in the vicinity of a spinning disc in order to improve fertiliser spreading in agriculture. In this approach, the acquisition system consists of a digital camera placed above the disc so that its view axis corresponds to the disc axle. This provides useful(More)
This paper describes the development of a device capable of measuring the dynamic friction coefficient of particles accelerated in a tube spinning in a horizontal plane. The dynamic friction coefficient is not the classical Coulomb friction coefficient, but a lumped parameter influenced by the Coulomb friction coefficient between particle and tube,(More)
