Abstract

This paper presents CFD heat transfer investigations in the leading edge cooling channel of the blade with different rib turbulator configurations. Analysis of heat transfer factor distribution along the cross section perimeter of the channel was carried out. The effect of rib configurations on the blade leading edge thermal state was also obtained.
