Mechanisms of instability growth, interaction and breakdown induced by a backward-facing step in a swept-wing flow
Autor: Jenna L. Eppink
Publikováno v: Journal of Fluid Mechanics. 931
Time-resolved particle image velocimetry measurements were performed downstream of a swept backward-facing step. The measurements allow detailed analysis of the interactions between the unsteady instabilities and the stationary crossflow vortices. Di

Mechanisms of stationary cross-flow instability growth and breakdown induced by forward-facing steps
Autor: Jenna L. Eppink
Publikováno v: Journal of Fluid Mechanics. 897
An experimental study is performed to determine the mechanisms by which a forward-facing step impacts the growth and breakdown to turbulence of the stationary cross-flow instability. Particle image velocimetry measurements are obtained in the boundar

Influence of a Backward-Facing Step on Swept-Wing Boundary-Layer Transition
Autor: Jenna L. Eppink, Rudolph A. King, Meelan M. Choudhari, Richard W. Wlezien
Publikováno v: AIAA Journal. 57:267-278
Experimental measurements were performed on a swept flat-plate model with an airfoil leading edge and imposed chordwise pressure gradient to determine the effects of a backward-facing step on transition in a low-speed stationary crossflow-dominated b

Effects of Forward-Facing Step Shape on Stationary Crossflow Instability Growth and Breakdown
Autor: Jenna L. Eppink, Cody Casper
Publikováno v: AIAA Aviation 2019 Forum.
The effect of forward-facing step shape on stationary-crossflow growth was studied downstream of a two-dimensional step in a swept-wing flow. The step height was set at 81% of the local unperturbed boundary layer thickness at the step location, and t

Validation and Uncertainty Analysis of Stereo Time-Resolved PIV Measurements for Boundary-Layer Transition Research
Autor: Jenna L. Eppink
Publikováno v: AIAA Scitech 2019 Forum.
An uncertainty analysis was performed on the stereo time-resolved particle image velocimetry measurements that were obtained in the boundary-layer of a swept wing model. Several different approaches were undertaken to estimate the uncertainty of the
