Assimilation of wall-pressure measurements in high-speed flow over a cone
David A. Buchta, Stuart J. Laurence, Tamer A. Zaki
A nonlinear ensemble-variational (EnVar) data assimilation is performed in order to estimate the unknown flow field over a slender cone at Mach-6, from isolated wall-pressure measu…

Concave-wall turbulent boundary layers without and with free-stream turbulence
Jiho You, David A. Buchta, Tamer A. Zaki
Direct numerical simulations are performed to contrast turbulent boundary layers over a concave wall without and with free-stream turbulence. Adverse pressure gradient near the ons…

Observation-infused simulations of high-speed boundary layer transition
David A. Buchta, Tamer A. Zaki
High-speed boundary-layer transition is extremely sensitive to the free-stream disturbances which are often uncertain. This uncertainty compromises predictions of models and simula…
