Mapping the Turn: An Eulerian Binormal-Axis Diagnostic for Recirculating 3D Flows
John Marshall Cooper, Wen Wu
Three-dimensional (3D) recirculating flows are often interpreted qualitatively from selected streamline visualizations. In separated flows, such recirculating motion is central to…

Separation of a Laminar Boundary Layer Subjected to Pressure Gradients with Spanwise Variations
John Marshall Cooper, Benjamin S. Savino, Benjamin Kellum Cooper +1
The characteristics of three-dimensional laminar separation bubbles (LSBs), compared with their quasi-two-dimensional counterparts, are studied using direct numerical simulation. A…

Pressure-Induced Separation of a Laminar Boundary Layer over a Partially-Slip Wall
Benjamin Kellum Cooper, Benjamin S. Savino, John Marshall Cooper +2
The characteristics of pressure-induced laminar separation bubbles (LSBs) over a partially-slip wall, compared with that over a canonical no-slip wall, are studied using direct num…
