Flowfield Downstream of a Compressor Cascade with Tip Leakage
… were the effects of tip gap height, and blade boundary layer trip variations. The results revealed the presence of two distinct vortical structures in the flow. The tip leakage vortex is formed due to the roll up the tip flow as it exits the tip gap region. A second vortex, counter-rotating …

Surface Structure and Its Effect on Reducing Drag
… model with an aircraft aluminum alloy skin with boundary layer trip strip served as a baseline for drag comparisons. The Fastskin FSI swimsuit fabric and those with similar rib patterns tended to reduce drag below that of the baseline and the trend was maintained with increasing Reynolds number. …

Optimal design of municipal and irrigation water distribution systems
… on the surface of the body with an artificial boundary layer trip.

An experimental study on the performance of existing and custom quiet propeller designs for unmanned aircraft systems
… modification to the propeller design such as a boundary layer trip on the leading edge top surface or serrations to the trailing edge has been shown to reduce the sound radiated by the propeller. In total, 37 quiet propeller designs were created and simulated using SolidWorks Flow Simulation. …

An experimental study of flow over a 6 to 1 prolate spheroid at incidence
… on the surface of the body with an artificial boundary layer trip. It was found that there exists a critical Reynolds number at which the flow characteristics of the afterbody changes. This critical Reynolds number was also confirmed by the force and moment tests. Above this Reynolds number, as …

Experimental wind tunnel study of airfoils with large flap deflections at low Reynolds numbers
Lift, drag, and moment measurements were taken at low Reynolds numbers for four airfoils with trailing edge plain flaps in an attempt to understand the effects of Reynolds number, percent thickness (t/c), percent chord of flap (flap-chord ratio), and flap deflection on airfoil performance. The four …
