A new column collapse apparatus for the characterisation of the flowability of granular materials
(2020-02)
Article
Open AccessThe packaging industry is lacking a standard methodology to characterise the granular flow of a wide range of powders and grains in actual handling conditions. We present a new fully-instrumented granular column collapse ... -
Digital image-based measurement of degree of saturation on moving soil
(Canadian Science Publishing, 2025-02)
Article
Open AccessThis paper presents a novel methodology that combines Particle Image Velocimetry - Numerical Particles (PIV-NP) and Short-Wave Infrared Spectral Imaging for the non-invasive measurement of displacements and degree of ... -
Experimental visualization study of the velocity flow in the bass-reflex port of a loudspeaker
(Universitat Politècnica de Catalunya, 2015-01-20)
Bachelor thesis
Restricted access - author's decisionA bass-reflex port is an open pipe that connect the volume of the loudspeaker with the surrounding environment. Its role is to accentuate the low frequency range of sound. For some geometries a vortex shedding can be ... -
Flow characterization study of straight minichannel devices using microPIV
(Universitat Politècnica de Catalunya, 2016-04)
Bachelor thesis
Restricted access - author's decisionIn the last decades there has been a growing interest to develop mi-croscale devices that can manipulate and transport relatively small volumes of fluids. These devices have applications in many areas of engineering, including ... -
Formation of tip-vortices on triangular prismatic-shaped cliffs. Part 1: A wind tunnel study
(2012)
Article
Restricted access - publisher's policySpeed-up over topography has long been recognized as significant for structural design and wind energy applications. Here wind flow over cliffs that have a sawtooth plan are studied for speed-up effects under different ... -
