Dust emission modelling around a stockpile by using computational fluid dynamics and discrete element method

Derakhshani, S.M. (author), Schott, D.L. (author), Lodewijks, G. (author)

Dust emissions can have significant effects on the human health, environment and industry equipment. Understanding the dust generation process helps to select a suitable dust preventing approach and also is useful to evaluate the environmental impact of dust emission. To describe these processes, numerical methods such as Computational Fluid...

Single-phase elastic metamaterials for wave filtering

Azevedo Vasconcelos, A.C. (author), Schott, D.L. (author), Aragon, A.M. (author), Jovanova, J. (author)

This paper discusses an elastic metamaterial for filtering energy from certain frequencies of an incoming wave. The unit cell, which is composed by a single material, is built to obtain a local resonance band gap. Since Bloch-Floquet's periodic condition is enforced to the unit cell, the dynamic characteristics of the metamaterial is obtained...

Minimization of wear in a transfer chute by geometric optimization of convex pattern surface: A DEM study

Yan, Y. (author), Vreeburg, Wouter (author), Chen, Guangming (author), Schott, D.L. (author)

Using bionic surface on the material equipment interface of bulk handling equipment is a promising solution for wear reduction. A bionic surface is a flat surface outfitted with a pattern of convexes that disrupt the natural sliding flow of bulk material. Previous numerical work has shown a significant reduction of wear of bionic surfaces...

Biomass pellet breakage: A numerical comparison between contact models

Gilvari, H. (author), de Jong, W. (author), Schott, D.L. (author)

The breakage behaviour of biomass pellets with a diameter of 6 mm under uniaxial compression test was studied experimentally and numerically using the discrete element method (DEM). Two types of the available bonding contact models in EDEM software were used to compare the macroscopic properties including the maximum stress at failure, strain at...

The Effect of Pellet Length on Mechanical Durability and Breakage Behaviour of Torrefied Biomass

Gilvari, H. (author), de Jong, W. (author), Schott, D.L. (author)

The transportation, handling, and storage of biomass pellets are challenging due to pellet breakage and fines generation. The amount of fines generated during transportation and handling of biomass pellets is mostly measured in the laboratory using mechanical durability testers such as tumbling can method according to ISO 17831-1. This standard...

Oscillating disc technology for rock excavation

Grashof, Bernd (author), Alvarez Grima, M. (author), Schott, D.L. (author), Helmons, R.L.J. (author)

Rock cutting is a challenging process. Heavy equipment, large cutting forces, high wear rates and large amounts of required energy are common challenges when cutting rock. Traditionally, rock cutting is based on a linear motion of the cutting tool. However, a significant improvement on the cutting performance is expected when using non-linear...

Demand forecast models for online supermarkets

Evers, J.M. (author), Tavasszy, Lorant (author), van Duin, Ron (author), Schott, D.L. (author), Gorte, Frank (author)

Food waste and incomplete orders at online supermarkets mainly occur due to inaccurate demand forecasting which leads to incorrect ordering of products. The objective of this study is to develop an accurate demand forecast model at product-level based on historical customer order data, give recommendations on implementation and describe impact...

Calibration of DEM Parameters for Multi-Component Segregation

Hadi, A.H. (author), Pang, Y. (author), Schott, D.L. (author)

Segregation or de-mixing is the phenomenon occurring in moving granular materials in which particles with similar properties, e.g., size, density and shape, accumulate. This de-mixing reduces the homogeneity of the mixture which is generally considered undesirable and should be minimised. Despite many experimental and numerical attempts to...
