Abstract: A key subject of interest for technologies that involve flows of fluids at the supercritical thermodynamic state is the development of prediction methods that capture the fluid dynamics and convection heat transfer at this ...

Abstract: This paper describes numerical simulations of the instability mechanisms in a separation bubble subjected to a threedimensional freestream pressure distribution. Two direct numerical simulations are performed of a separation ...

Abstract: This study presents experimental results on the effects of riblets on the coherent structures of turbulence within a turbulent spot. The riblet spacings of the study correspond to 0.5 and 1.5 times the natural spacing of ...

Abstract: Modeling of deterioration of heat transfer (DHT) observed in fluid flows at supercritical pressure remains a challenge due to incomplete understanding of the underlying physics. Given the challenges involved in the ...
