A Numerical Study on Compressible Flows over Thick Airfoils for Tilted Wind Turbines

While the assumption of incompressible flow has been the prevailing standard for numerical simulations of wind turbine aerodynamics, the limit of this assumption is approached as the industry progresses towards increasingly higher operational tip speeds. This thesis explores the implications of compressibility and transonic flow phenomena,...

Lime Treatment: Evaluation for Use in Dike Applications in the Netherlands

This study aimed to assess the suitability of lime treatment for use in dikes in the Netherlands. The effect of this technique on the behavior of a Dutch clay was addressed by comparing the detailed response of lime-treated and natural samples at different lime contents (1.25% and 2.25%) and curing periods. A series of laboratory tests...

On sub-surface stress caused by contact roughness in compressible elastic solids

Contact between elastic bodies with self-affine rough surfaces is mostly studied with a focus on determining surface fields, despite body fields are of great importance to establish, for instance, when and where elasticity breaks down. This work aims at analyzing the effect of contact roughness on the body fields of compressible frictionless...

Reservoir compaction in shallow gas reservoirs: The impact of production-induced reservoir compaction on the recovery of gas from shallow reservoirs

Compaction occurs in many consolidated hydrocarbon reservoirs and is responsible for both improvement and loss of recovery. This study assesses the effects of rock compaction and the consequences on the production and recovery in unconsolidated shallow gas reservoir a topic of which little is known. The compaction behaviour in unconsolidated to...
