Conference paper


In this work, silo discharge was viewed as a complex fluid flow, in order to perfect a new technique for the measurement of flow rate. Flow rate was investigated using a non intrusive method measuring the evolution of the free surface profile during the discharge flow. This method consisted of recording via a CCD sensor, the evolution of the free surface by laser planes, and then obtaining by processing the free surface position and shape over time.
