Due to the requirement for enhanced cooling technologies on modern gas turbine engines, advanced research and development has had to take place in field of thermal engineering. Among the gas turbine cooling technologies, impingement jet cooling is one of the most effective in terms of cooling effectiveness, manufacturability and cost. The chapters contained in this book describe research on state-of-the-art and advanced cooling technologies that have been developed, or that are being researched, with a variety of approaches from theoretical, experimental, and CFD studies. The authors of the chapters have been selected from some of the most active researchers and scientists on the subject. This is the first to book published on the topics of gas turbines and heat transfer to focus on impingement cooling alone.

The overall objective of the program is to enhance the effectiveness of turbine cooling by exploiting the presence and structures of vortices. Program A is concerned with jet impingement cooling and addresses the effects of bulk fluid rotation on jets, their vortical structures and cooling. A low-speed rotating water tunnel has been constructed for flow-visualization study of impinging jets in rotation: in addition, a rotating air rig was also constructed. The results show that the Contour of the impinging jet is crucial in determining the jet trajectory and both the favorable and adverse effects of rotation have been identified in the context of impingement cooling. Program B is concerned with convective and film-cooling. It focuses upon the so-called tornado effect, or the corewise transport of heat through the legs of hairpin vortices, which could lead to enhanced cooling in turbulent flows. An explicit confirmation of the effect have been established by ain water and unsteady heat transfer measurements in air. (AN).
