Oblique ribs are widely applied to the internal cooling of turbine blades to promote the heat
transfer between blade wall and coolant. In this study, the effect of several new types of …

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 …

Repeated ribs are often employed in the midsection of internal cooling passages of turbine
blades to augment the heat transfer by air flowing through the internal ribbed passages …

In this research, three W-shaped ribs are taken to analyze their influence on the heat transfer
rate in the internal cooling of a gas turbine blade at constant e/D h (0.037) and heat flux. The …

The thermal efficiency of gas turbine engines depends heavily on the cooling performance
of the internal channels of turbine blades. In the present study, the effects of bidirectionally …

Ribs are often used in the mid-section of internal turbine blades to augment heat transfer
from the blade wall to a coolant, but most research works are concerned only with …

Rib turbulators are widely applied in internal cooling channels of gas turbine blades to
improve cooling performance. In this study, heat transfer and friction factor were investigated …

A wavy rib with the simple structure is proposed for the internal cooling channel in turbine
blade, in order to enhance heat transfer and reduce pressure loss. The heat transfer …

Purpose The fluid flow in a rotating channel is obviously different from that in a stationary
channel due to the existence of Coriolis force, which, in turn, enhances the heat transfer on …

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 …
