Numerical modelling of liquid infusion into fibrous media undergoing compaction

Numerical Modelling of Dynamic Compaction in Dry Sandy Soils for Determination of Effective Print Spacing

Dynamic compaction (DC) is a widely used soil improvement method in dry and/or saturated soils. The design of DC treatment is usually carried out based on the past experiences and empirical relations. In order to clarify the ambiguities in DC processes, numerical modeling of DC in dry granular soils has been considered using a dynamic finite element code. Using the developed model, two design c...

Numerical Simulations of Viscoelastic Flows in Fibrous Porous Media

Numerical Investigation of Flow in Fibrous Porous Media

Fibrous porous materials involve in many natural and engineering processes. In this study, the permeability of ordered fibrous media towards normal and parallel flows is studied numerically. Porous material is represented by a “unit cell” which is assumed to be repeated throughout the media and 1D fibers are modeled as a combination of Channel-like conduits. The numerical results are successful...

Numerical simulation of dynamic soil compaction with vibratory compaction equipment

Roller drums make use of various shapes and their dynamic compaction effect is achieved by different kinds of dynamic excitation systems. The bearing capacity of layered soil constructions can be measured during the soil compaction process. The finite element method has been applied for dynamic analyses using elastic models. For the realistic simulation of the dynamic compaction process it is n...

Numerical modelling and simulation of liquid-impelled loop reactor

A liquid-impelled reactor (LLR) system was modelled using macro-and micro-balance technique. The relative goodness of using macro-balance was evaluated by comparing its solutions with the results obtained using micro-balance modell. The micro-balance modell formulated was used to investigate the dynamic behaviour of the system and to crosscheck the effectiveness of macro-balance modell. A numer...
