The repositioning and detachment of particulate structures deposited onto a single elastic polyurethane fibre which is subjected to axial stretching at low surrounding gas flow velocities has been investigated experimentally by Poggemann et al. [1]. The present study aims to model the physical phenomena observed during the first part of aforesaid experiment using the Discrete Element Method (DEM), wherein the particle-loaded fibre is stretched without considering a surrounding gas flow. Set-up conditions for the numerical simulation have been adopted from the prescribed experiment. The fibre material and the particulate matter deposited onto the fibre have been modelled using the bonded discrete element model [2] and the JKR [3] cohesion model, respectively. The simulative investigation of the second part of the study by Poggemann et al. [1], involving fluid particle interaction will be conducted at a later stage by means of unresolved CFD-DEM simulations. The aim of the present study is to understand the process of crack initiation within the particulate matter deposited on the fibre surface and particle repositioning due to extensional forces imposed at the fibre ends. Following the referenced experimental study, the particulate matter was considered to consist of glass particles having a mean diameter of d50,3 = 7.73µm. The employed modelling approach captures the elastic behaviour of the fibre, the interaction between the fibre surface and the particulate matter and also between the particles forming the particulate structure. This simulation tool can aid in predicting the required conditions (appropriate shear force, stretching velocity and frequency in case of time-periodic stretching) for the regeneration of elastic filter, thereby improving its design.
