Analysis of two- and three-dimensional flow separation
… (1904) showed that streamlines in a steady flow past a two-dimensional streamlined body separate from the boundary where the skin friction (or wall shear) vanishes and admits a negative gradient. Although commonly thought otherwise, these separation conditions are purely kinematic: They can …

Three Dimensional Flow Within Conduits of Arbitrary Geometrical Configurations
… scheme has been developed along with a three dimensional transformation procedure for arbitrary non-orthogonal coordinate systems, for the purpose of the predictions of the three dimensional turbulent flows within ducts of arbitrary geometrical configurations.

Three dimensional flow analysis by the vortex-lattice method
… (VLM) has been developed for the analysis of three-dimensional lifting bodies undergoing arbitrary motions. So far, the present method has been applied to thin surfaces in translational motion. Several cases were tested, such as rectangular, delta, sweptback and trapezoidal planforms. Emphasis …

A simple criterion for three-dimensional flow separation in axial compressors
Most modem blade designs in axial-flow compressors diffuse the flow efficiently over 20% to 80% of blade span and it is the endwall regions that set the limits in compressor performance. This thesis addresses the estimation, control and mitigation of three-dimensional separation near the hub corner …

Three-dimensional flow-induced dynamics of the endothelial surface glycocalyx layer
… in the vasculature. This thesis studies the flow-induced dynamics of the endothelial glycocalyx layer and reports the first direct measurement of the in vitro mechanical properties as well as the thickness of the glycocalyx through a novel optical imaging approach. Here, we have developed an …

Estimation of axial compressor body forces using three-dimensional flow computations
… curvature calculation and an unsteady, three-dimensional flow simulation. A two-dimensional body force representation is defined as a benchmark to evaluate the departures of the computed forces from two-dimensional behavior. The most important contribution to this departure (for both the …

Numerical, field and laboratory studies of three-dimensional flow structures at river channel confluences
… investigates controls on and the nature of three-dimensional flow structures at river channel confluences. Previous work has shown that junction angle is an important control on the flow patterns at channel junctions since it affects the degree of curvature of flow from each tributary and …

High Resolution Measurements of the Mean Three-dimensional Flow Field in a Natural River
The flow velocity in a river is three-dimensional (3D), turbulent, and varies in time and space. Capturing this variability in field measurements to support studies of river processes has proven particularly challenging. While originally developed to measure discharge, boat-mounted acoustic Doppler …

Development of a Sensor for Inflight Detection of Three-Dimensional Flow Separation on a Wing
… need exists for a sensor capable of detecting flow-field separation on an airplane wing during routine flight operations. A sensor of this type could lead to both improved flight safety and increased performance. It would also contribute to future separation control technologies. A new idea is …

A measurement system for turbulence properties in a three- dimensional flow using a data logger
… of mean velocities and turbulent stresses in a three dimensional flow field with a predominant flow direction. The experimental data can be taken with an automated traverse under the control of a digital data acquisition system which has been modified for this particular application.

The Impact of Three Dimensional Flow Anisotropy and Transients on Turbulence Ingestion Noise in Open Rotors
The effect of flow anisotropy and three dimensional separation on the turbulent structure and radiated turbulence ingestion noise of a rotor in two experimental configurations is studied. The first consists of a non-axisymmetric boundary layer wake ingested by a rotor mounted at the aft of a body …
