Estudio de flujos granulares de tipo geológico por medio del simulador multisensor GRANFLOW-SIM

Abstract: Estudio de flujos granulares de tipo geológico por medio del simulador multisensor GRANFLOW-SIM 265 ResumenLas avalanchas y los flujos de escombro producidos por eventos catastróficos como las erupciones volcánicas se pueden entender como enormes flujos granulares. Debido a la imposibilidad de predicción y de la peligrosidad de dichos eventos por las altas temperaturas y las masas en movimiento involucradas, su estudio se limita a la observación remota y a la medición de los depósitos generados. La observación… Show more

“…The laboratory experiments were carried out using a flume facility designed and built up at the Instituto de Geología (University of San Luis Potosi, Mexico; Bartali et al 2012) using an acrylic rough-bottom flume with transparent glass sidewalls that allows real-time observation of the moving granular avalanches. It is a modular apparatus, whose geometric characteristics can be readily modified to satisfy different experimental needs.…”

“…The apparatus is equipped with a modular system of multiple high signal/noise ratio (low noise) sensors working with an acquisition depth of 16 bit and a sampling rate up to 1000 samples per second (Fig. 1a; Bartali et al 2012).…”

“…All experiments were carried out using GRANFLOW-SIM (Fig. 1), a modular experimental flume designed and developed at the LAIMA (Image Analysis and Analogue Modelling Laboratory, for its Spanish acronym) at the Geology Institute of the Universidad Autónoma de San Luis Potosí, Mexico (Bartali et al, 2012(Bartali et al, , 2015. It consists of three main modules: i) a charge box, ii) a flume, and iii) an expansion box (Fig.…”

“…The use of these facilities represents a unique opportunity for observing and measuring processes that can be scaled to real events (Iverson et al, 1992, Dellino et al, 2007, 2010a, 2010bSulpizio et al, 2009;Bartali et al, 2012Bartali et al, , 2015Dioguardi et al, 2013). Another advantage of laboratory experiments is the ability to control boundary conditions that can influence flow variables.…”

“…The laboratory-scale devices of Roche et al (2010), Rowley et al (2014), Smith et al (2018) consist of straight horizontal flumes aimed to investigate the internal and depositional processes of CPCs in a confined configuration. On a larger scale, the 20 m long apparatus PELE (Lube et al 2015) and the 11 m long apparatus GRANFLOW-SIM (Bartali et al 2012, Sulpizio et al 2016) are straight inclined flumes with a constant slope angle, which are terminated by unconfined flat areas. Hence, none of these existing experimental apparatuses admits a non-straight channel morphology with bends or obstacles, neither flat channel banks to receive an overflow.…”
