The capabilities and limitations of the quadratic constitutive relation in computing streamwise corner flows are investigated using publicly-available data from direct numerical simulations of a square duct flow. The increased accuracy of RANS comput

Experiments on supersonic flows are typically conducted in wind tunnels with rectangular cross-sections, which use two-dimensional nozzles of two different types. A “full” setup consists of two contoured nozzle surfaces symmetric about the tunnel

Streamwise-coherent structures were observed in schlieren images of a Mach 2.5 flow in an empty supersonic wind tunnel with a rectangular cross section. These features are studied using Reynolds-averaged Navier–Stokes computations in combination wi

The quadratic constitutive relation was proposed as an extension of minimal complexity to linear eddy-viscosity models in order to improve mean flow predictions by better estimating turbulent stress distributions. However, the successes of this modif

Wind tunnel experiments are conducted to investigate the effect of the corner regions of a Mach 2.5 channel flow on the response of the floor boundary layer to an oblique shock. To study this, two different nozzle setups are used, which produce disti

Validation studies are becoming increasingly relevant when investigating complex flow problems in high-speed aerodynamics. These investigations require calibration of numerical models with accurate data from the physical wind tunnel being studied. Th

In supersonic flows, the separation in streamwise corners is a significant and widely encountered problem which can not be reliably predicted with the numerical methods commonly used in industry. The few previous studies on this topic have suggested
