High flow nasal oxygen in resource constrained, non-intensive care high care wards for COVID-19 acute hypoxaemic respiratory failure: comparing outcomes of first versus third waves by Audley, Gordon George

“…Background: High flow nasal oxygen (HFNO) is an accepted treatment for severe COVID-19 related acute hypoxaemic respiratory failure (AHRF) especially where limited access to intensive care unit (ICU) resources exists, and approximately halves the need for invasive mechanical ventilation. …”

Computational analysis of viscoelastic fluid dynamics with applications to heat exchangers by Mavi, Anele

“…In addition, the effects of pressure, momentum, extra stresses, temperature, viscosity and relaxation time on the fluid temperature are investigated; both in the counter flow and parallel flow configurations. Graphical computational results are presented and discussed quantitatively and qualitatively with respect to several parameters involved in the problem.…”

On the Evaluation of Common Design Metrics for the Optimization of Non-Axisymmetric Endwall Contours for a 1-stage Turbine Rotor by Bergh, Jonathan

“…While both designs produced using the compound design objective functions were predicted to improve both the conditions for the target blade row, as well as the flow quality at the exit of the blade row, flow separations at the exit of the contoured regions for both designs resulted in only partial validation of each design when tested experimentally. …”
