In this study, the heat transfer and friction characteristics of four different rib geometries-45°
angled, V-shaped, W-shaped and M-shaped ribs in a two-pass stationary channel have …

Herein, 50 articles published over the past 20 years on using large eddy simulation (LES) for
the internal cooling passage of a gas turbine, especially the mid-chord ribbed channel, are …

Numerical and experimental studies are conducted on heat transfer and pressure loss in a
three-pass serpentine channel with trailing bleed holes. The guide vanes' effects in the …

This two-part paper addresses the design of a U-bend for serpentine internal cooling
channels optimized for minimal pressure loss. The total pressure loss for the flow in a U …

Described in this paper is a numerical investigation on the concept for improving thermal
performance of internal cooling by placing the convergent and divergent slit ribs. Five …

This paper shows experimental results obtained from a T100 microturbine connected with
different volume sizes. The activity was carried out with the test rig developed at the …

Varying aspect ratio (AR) channels are found in modern gas turbine airfoils for internal
cooling purposes. Corresponding experimental data are needed in understanding and …

This two-part paper addresses the design of a U-bend for serpentine internal cooling
channels optimized for minimal pressure loss. The total pressure loss for the flow in a U …

This paper presents an investigation on the cooling performance in a ribbed channel with
the pulsating inlet flow. The flow structures and heat transfer characteristics are simulated by …

Detailed experimental and numerical investigations are conducted on the heat transfer,
pressure loss and flow structure characteristics of a serpentine channel with multiple short …
