Confined granular flow in silos with inserts - Full-scale experiments
Wójcik, M.; Tejchman, J.; Enstad, Gisle (Journal article; Peer reviewed, 2012)The paper describes results of experimental investigations of confined granular flow in a silo with different inserts. Over 100 experiments were carried out with dry cohesionless sand in a large metal silo with and without ... -
Development of normal pressure and frictional traction along the walls of a steep conical hopper during filling
Ding, Songxiong; Rotter, J.M.; Ooi, J.Y.; Enstad, Gisle (Journal article; Peer reviewed, 2011)A novel progressive filling approach was adopted in a numerical effort to represent the pilling process of particulate solids. It was implemented in a finite element analysis to investigate the development of loads along ... -
Effect of operating conditions and particle properties on performance of vertical air-lift
Chladek, Jana; Enstad, Gisle; Melaaen, Morten Christian (Journal article; Peer reviewed, 2011)The effect of the fluidization air flow rate and the transport air velocity on the solids mass flow rate and the pressure drop along the transport pipe was investigated in a vertical air-lift. The use of two different ... -
Experimental investigation of load exerted on a double-cone insert and effect of the insert on pressure along walls of a large-scale axisymmetrical silo
Ding, Songxiong; Dyrøy, A.; Karlsen, M.; Enstad, Gisle; Jecmenica, Mladen (Journal article; Peer reviewed, 2011-03-03)Applications of flow aid devices (commonly referred as inserts) improve the silo discharging mode. Considerable efforts have been made in finding best configurations between the inserts and silos to achieve the optimal ...
