Analytical prediction of the unsteady lift on a rotor induced by downstream flow obstructions
… the upstream potential disturbance of downstream flow obstructions. The method is applied to a particular geometry which consists of a rotor, a downstream stator, and downstream struts which support the engine casing. Using the Douglas-Neumann singularity superposition computer program to model …

Flow and Heat Transfer in Tubes with Obstacles
… and pressure loss in heated tubes equipped with flow obstacles by experimentally investigating the axial and circumferential distributions of convective heat transfer in a heated tube, complemented by pressure loss and velocity measurements in an adiabatic pipe flow. The heat transfer experiments …

Sensitivity analysis and computational shape optimization for incompressible flows
… of a cost functional defined for a fluid flowing through a channeL Parameters control the shape of an obstruction in the flow, and the strength of the inflow. The problem is discretized using finite elements. Optimization algorithms are considered which use either finite differences or …

A regional study of landslide hazards and related features in the Upper Indus River Basin, northern Pakistan
… dam sites because these features often create flow obstructions. To test this hypothesis, 251 knickpoints were identified and marked along the channel profile of the Indus River, then compared with the mapped and known landslide dam sites. The comparison revealed that the channel's longitudinal …

River-Floodplain Connectivity and Sediment Transport Potential: Applications to Sediment Dynamics on Floodplains and Juvenile Freshwater Mussel Settling in Rivers
… floodplain in Virginia, incorporating hydrologic flowpaths as an explicit measure of river-floodplain connectivity can improve predictions of floodplain sediment deposition. Three regression models were developed incorporating flow pathways and the best model was applied to hydrodynamic model …

Channel Morphology and Riparian Vegetation Influences on Fluvial Aquatic Habitat
… the distribution of two-dimensional (2D) flow complexity metrics at the meso-habitat scale as explanatory variables for brook trout habitat preferences and as potential metrics to evaluate habitat restoration design. Spatial hydraulic complexity metrics, including area-weighted circulation …
