Axial compressor stall.
… the prediction of the in-stall performance of axial flow compressors. A new, on-line, phase-lock sampling technique has been developed, which, for the first time, allows the quasi-continuous recording of instantaneous velocity, pressure and flow direction measurements from within the stall …

Axial compressor stability enhancement
… cut into the casing above the rotor blades, and axial slots cut into the casing adjacent to the rotor blade leading edges. The performance of a single casing groove is measured at different axial locations over the blade tips. For the first time, it is shown that there are two locations where …

ANALYSIS OF FRAME-CORE WALL BUILDINGS CONSIDERING EFFECTS OF AXIAL FORCE AND AXIAL DEFORMATION
The effects of axial force and axial deformation in columns on dynamic characteristics of frame-core wall tall buildings are considered in the present study. The governing equations of motion for the structure are formulated through a continuum approach idealizing the whole structure as a …

Axial Capacity of Drilled Shafts
Less scatter is demonstrated for shafts in clay versus those in sand. More scatter is apparent for shafts constructed using slurry. Little scatter is shown for cased shafts. No trend is shown for slump, date of construction, or type of drilling tool. No significant effect is found for the rate of …

Modular Multi-Stage Axial Compressor Design
… components, such as multi-stage axial compressors. It is the objective of this approach to utilize a "core" module in all the compressors, thus maximizing commonality and minimizing all relevant development, design, manufacture, procurement, and service costs; these reductions in …

Tip-clearance effects in axial compressors
The flow in the tip-clearance gap of a compressor has a profound effect on its performance, but understanding of the actual flow phenomena involved is limited. The current work aims to improve the situation through a comprehensive set of tests on a compressor with different clearance sizes and …

Unsteady Aerodynamics of Compact Axial Compressors
Compact axial compressors are of interest to the domestic appliance industry. The associated low Reynolds number leads to high losses compared to large-scale compressors due to a transitional flow field with large regions of separation. This thesis investigates how Reynolds number variations affect …

Performance limits of axial turbomachine stages
… assesses the limits of stage efficiency for axial compressor and turbine stages. A stage model is developed, consisting of a specified geometry and a surface velocity distribution with turbulent boundary layers. The assumptions and parameterization of the stage geometry allow for calculation …

Optimization of Conformal Joints in Axial Tension
<p>Electromagnetic forming uses high current to form conductive material. It has been a possible manufacturing technique for joining materials since the 1960s. In the past decade the process has seen a resurgence due to the desire for lightweight manufacturing. The process provides a means to join …
