Hydrodynamic resistance and sorting of deformable particles in microfluidic circuits
… that enabled completely new functionalities. Hydrodynamic resistance, the extra resistance induced by a particle as it flows through a microfluidic channel, has been recently proposed as a viable property for particle characterization. Particle-induced hydrodynamic resistance can be linked to …

Self-sorting of deformable particles in a microfluidic circuit
… for sorting of deformable particles based on the hydrodynamic resistance induced in a microchannel. Hydrodynamic resistance can be related to physical properties, including size and deformability of the particle, and can also be influenced by particle-wall interactions, hence allowing sorting …

A Hydrodynamic Analysis and Conceptual Design Study for an External Storage Enclosure System for Unmanned Underwater Vehicles.
… capabilities. This research investigates the hydrodynamic resistance and powering requirements needed to support a conceptually designed rigid multi-bodied UUV built around DARPA’s SUBOFF hull from, the goal being to develop new and innovative low-cost methods of modifying commercially …

Flow-Transport Modeling and Quantification
… river. Correlations were performed relating the hydrodynamics of the river to the bed form types and geometries. The research work showed the inability of hydrostatic numerical modeling systems to accurately predict flow separation at the bed form crest but indicated that these models could …

Nanoporous elements in microfluidics for multi-scale separation of bioparticles
… interception and the reduction of near-surface hydrodynamic resistance. We verified that the improvement of interception efficiency also results in an increase in capture efficiency when comparing nanoporous VACNT post arrays with solid PDMS post arrays of the same geometry, using both bacteria …

Active and passive separation control for drag reduction of a maneuvering hull form
… and air vehicles in particular is limited by resistance due to cross-flow separation. Hull forms with lower hydrodynamic resistance in maneuvers are able to follow trajectories with tighter turns and at higher speeds. Despite the progress that has been made in the control of two dimensional …

A clinical role for fluid dynamics modelling of arteriovenous fistulae
… with high transWSS. The calculation of hydrodynamic resistance was found to be a useful identifier for the presence of disease, as well as the subsequent removal following these procedures, as significant reductions in resistance were seen following successful procedures, whilst other …

Microfluidic engineering of water purification
… mass transport while keeping the effect on the hydrodynamic resistance small. Next, we built an empirical model to estimate an electrical energy consumption of ICP desalination and utilized it to obtain the water cost and optimal operating parameters for high salinity applications. We performed …

Geometry and Hydrodynamics of Swimming with a Bundle of Bacterial Flagella
… We use two well-established theories for the hydrodynamics of slender filaments, namely resistive-force theory (RFT) for the analytical calculations and slender-body theory (SBT) for the numerical simulations. The first part of the thesis, comprising three chapters, deals with the geometric …
