Abstract: In this paper, a transient method for measuring heat transfer coefficients in internal cooling systems using infrared thermography is applied. The experiments are performed with a twopass internal cooling channel connected ...

Abstract: Impinging jets have become an indispensable measure for cooling applications in gas turbine technology. The present study seeks to explore the flow field dynamics inside an eniginerelevant cooling passage of trapezoidal ...

Abstract: The experimental and numerical heat transfer results in a trapezoidal duct with two staggered rows of inclined impingement jets are presented. The influence of changes in the jet bore geometry on the wall heat transfer is ...

Abstract: An investigation was conducted to assess the thermal performance of Wshaped, 2Wshaped and 4Wshaped ribs in a rectangular channel. The aspect ratios (W/H) were 2:1, 4:1, and 8:1. The ribs were located on one channel wall. ...
