Including stochastic behaviour of granular materials in design of bulk handling equipment

Granular materials are all around and have many secrets that still need to be unravelled. This thesis shows how the stochastic behaviour of granular materials can be identified and efficiently included in design of bulk handling equipment. To achieve this, metamodels play a key r ...
Background: Risk-based breast cancer (BC) screening raises new questions regarding information provision and risk communication. This study aimed to: 1) investigate women’s beliefs and knowledge (i.e., mental models) regarding BC risk and (risk-based) BC screening in view of impl ...
In design optimization of bulk handling equipment (BHE) we generally focus on the mean performance of the equipment. However, granular materials behave stochastic due to irregularities in particle shape and size which leads to stochastic performance of the equipment. To include t ...
In calibration of model parameters for discrete element method (DEM) based models the focus lies on matching the mean key performance indicator (KPI) values from laboratory experiments to those from simulation results. However, due to the stochastic nature of granular processes e ...
Developments in discrete element modelling (DEM) enable detailed modelling of granular flows in bulk handling equipment (BHE) but due to the computational expense of DEM, wide use in analysing equipment performance is not yet feasible. Metamodels are a viable option to effectivel ...
The work presented in this paper demonstrates the use of metamodels to capture the relations between the discharge flow and the design parameters of a silo. Based on simulation data for a discharging silo a metamodel is developed that relates the size of the discharge opening and ...
