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 …

Gas turbines are widely used for aircraft propulsion, land-base power generation, and other
industrial applications like trains, marines, automobiles, etc. To satisfy the fast development …

Ribs are often employed in internal cooling passages of turbine blades to augment heat
transfer with cooling air flowing through the internal ribbed passages. The present work …

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 …

The present work concentrates on perforated 90° ribs to improve the thermal performances
in a rectangular cooling channel with an aspect ratio of 4: 1. Three different types of …

Due to the complex flow, designers need data that will aid them in the development of
efficient cooling designs. They need detailed hot gas path heat transfer distributions. Heat …
