TL;DR: In this article, the authors measured the local aerodynamic and heat transfer performance in a rib-roughened square duct as a function of the rib pitch to height ratio, and showed that simple correlations derived from the law of wall similarity and from the Reynolds analogy could not be applied for the present rib height-to-channel hydraulic diameter ratio (e/D h = 0.1).

TL;DR: In this paper, the authors studied the tip leakage flow characteristics for flat and squealer turbine tip geometries in the von Karman Institute Isentropic Light Piston Compression Tube facility, CT-2, at different Reynolds and Mach number conditions.

TL;DR: In this paper, an experiment with a highly loaded transonic turbine nozzle guide vane mounted in a linear cascade arrangement is presented, where a simulation of Mach and Reynolds numbers as well as of the gas to wall temperature ratio compared to the values currently observed in modern aero engines is performed in a short duration Isentropic Light Piston Compression Tube facility.

TL;DR: In this article, a quasi-3D unsteady Navier-Stokes computation using a k-? turbulence model and a modified version of the Abu-Ghannam and Shaw correlation for the onset of transition is presented.

TL;DR: In this paper, the progress in fast response measurement techniques for high speed turbomachines and application with emphasis on fast response pressure and temperature probes and blade surface sensors including pressure, heat transfer and shear stress determination.
