An Experimental Correlation for Friction Factor in Horizontal Pipe with Trapezoidal Section Inner Longitudinal Slots for Conveying of Solids

In order to increase the efficiency of the conveyance of the granular solids, a new experimental set-up is designed. The test rig has longitudinal trapezoidal slots in its conveying pipes. Through experimentation, a correlation for friction factor in terms of solid mass flow rate, fluid flow rate and Froude number is presented. It is shown that the mixture friction factor for pipes with inn...

Numerical Simulation of Granular Column Collapses with Pressure-Dependent Viscoplastic Model using the Smoothed Particle Hydrodynamic Method

This paper presents a numerical analysis of granular column collapse phenomenon using a two-dimensional smoothed particle hydrodynamics model and a local constitutive law proposed by Jop et al. This constitutive law, which is based on the viscoplastic behaviour of dense granular material flows, is characterized by an apparent viscosity depending both on the local strain rate and the local press...

Reducing the Forces Caused by Earthquake on Retaining Walls Using Granulated Rubber-Soil Mixture

In recent years, various studies have been undertaken on how to use waste materials in civil engineering projects. Among waste materials, waste rubber has been highlighted to be used for different purposes such as reinforcing of soil and making of reinforced slopes. To investigate the properties of granulated rubber-soil mixture and its application in making of slopes behind retaining walls, so...

Cluster growth in two- and three-dimensional granular gases.

Dissipation in granular media leads to interesting phenomena such as cluster formation and crystallization in nonequilibrium dynamical states. The freely cooling system is examined concerning the energy decay and the cluster evolution in time, both in two and three dimensions. We also suggest an interpretation of the three-dimensional cluster growth in terms of percolation theory, but this poin...
