EFFECT OF JET DIAMETER ON HEAT TRANSFER IN A TWO-PASS CHANNEL

Abstract

Several methods are employed in the cooling of gas turbines. One such cooling method used in various locations of gas turbines utilizes air jets. In this study, a separator with jet holes was placed between two cooling channels within a gas turbine wing and the change in heat transfer values was examined. The experiments were conducted using three different jet diameters for four different Reynolds numbers in the channel. Liquid crystal and thermochromic liquid crystal techniques have been used in this study. The aim of this experiment is to contribute to research on the effect of a separator placed within a channel on the cooling performance and to the find the most convenient cooling performance.
